Stegonotus caligocephalus sp. nov. Dark-headed Sabah Groundsnake (Figs. 3–6, Table 2) Holotype. FMNH 251054 (field number RFI 49331), an adult female from near the Gunung Emas [Gunung Alab] Telekom tower, Crocker Range National Park, Tambunan District, Sabah State, Malaysia, ca. 5.83°N, 116.34°E (Fig. 1), elevation ca. 1950 m, collected on 19 January 1993 by the American herpetologist Robert F. Inger (1920–2019), Curator of Amphibians and Reptiles at the Field Museum, Chicago, Illinois, USA, from 1954–1994 (Matsui 2019). Paratype. USNM 130244, an adult female, from “Bundu Tuhan, Mount Kina Balu, Ranau District, Sabah ” [Malaysia], ca. 6.05°N, 116.53°E, elevation 1370 m, collected on 1 August 1951 by the American mammalogist David H. Johnson (1912–1996), Curator of Mammals at the National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA, from 1941–1965 (Perry 2007). Referred specimen. ZMB 47866, a juvenile female from “Mt. Kinabalu” (no further locality data), elevation 1500 m, collected on 13 December 1988. Whereas the information in the collection’s ledger indicates that the specimen was collected by the German-South African herpetologist Thomas Ulber, this appears to be an error in both date and time. Ulber (in litt.) visited Mount Kinabalu in November 1989 but collected no snake specimens. Diagnosis. Stegonotus caligocephalus is a medium-sized (maximum SVL = 1071 mm) snake with a relatively short tail (SCR ♀ = 0.21), the shortest in the genus Stegonotus. It can be distinguished from all other known Stegonotus species by the following combination of characters: (1) rostral extending onto the dorsal part of the head intruding into the internasal area but not reaching the level of the nasals (character state: gull wing +; Fig. 4A, A’); (2) area of prefrontals three times that of the internasals, internasal suture one-fourth to one-third the length of the prefrontal suture (SSR 0.25–0.33, mean = 0.28); (3) frontal clearly pentagonal with well-formed corners and a slightly concave anterior suture; (4) AE lies at the same level as the anterior end of the frontal; (5) length of frontal three-fourths that of the parietal suture (FPR = 0.75); (6) PfS one-fourth to one-third the length of external head-scale length (HSR = 0.25–0.31). (7) PF Comparisons. In the following comparisons, characteristics of S. caligocephalus are listed in parentheses. The number of specimens used to determine ranges of continuous characters follows species names. Based on our previous analysis of Stegonotus (Kaiser et al. 2019) there does not appear to be any sexual dimorphism in the Bornean or Philippine species we compare in detail below. Given how few specimens of these populations are available in museum collections, combining scale count data for females and males in the absence of sexual dimorphism therefore increases our sample size and improves our analysis. Furthermore, given the geographic position of this Bornean population, most Stegonotus species can be considered extralimital to this comparison. It is highly unlikely that a New Guinean population disperses all the way across Wallacea into Borneo. After presenting an exhaustive comparative section in the description of S. ayamaru (Kaiser et al. 2019), we are confident in limiting our detailed, formal comparisons to Stegonotus from Borneo and the Philippines and eliminate other species based on different dorsal scale counts (S. admiraltiensis, S. diehli, S. dorsalis, S. florensis, S. guentheri, S. poechi, S. sutteri), significant differences in number of gastrosteges (S. admiraltiensis, S. aruensis, S. ayamaru, S. derooijae, S. diehli, S. guentheri, S. heterurus, S. keyensis, S. lividus, S. melanolabiatus, S. modestus, S. parvus, S. poechi), strongly diverging rostral morphology (S. aruensis, S. australis, S. batjanensis, S. cucullatus, S. dorsalis, S. iridis, S. parvus, S. poechi), the configuration of supralabials touching the eye (S. aruensis, S. ayamaru, S. batjanensis, S. derooijae, S. diehli, S. florensis, S. heterurus, S. lividus, S. melanolabiatus, S. modestus, S. parvus, S. poechi, S. sutteri), and differences in head and body color (S. batjanensis, S. florensis, S. iridis, S. modestus, S. reticulatus, S. sutteri). Where appropriate, gender is indicated throughout by subscripted male (³) and female (♀) symbols for ease of reference; when sexes are combined there is no subscript. Given that the three extant specimens of S. caligocephalus are all females, we separately provide data for females of the other species. A listing of those characters most relevant for interspecies comparisons is provided in Table 2. Stegonotus borneensis (n = 1³, 1♀) has a significantly (unpaired t -test, t = 6.97, P t = 4.98, P S. borneensis, the values for ventral and subcaudal count are 193 and 78, respectively. As a consequence, the SCR in S. borneensis is higher, at 0.28–0.29 (0.21–0.24). Additional differences include (1) SSR = 1/5 (1/4 or 1/3); (2) FPR = 4/5–7/8 (3/4); and (3) a uniform dark body coloration (head darker than body). The closest known locality for S. borneensis is in Sarawak State, Malaysia, a horizontal distance of ca. 560 km by air from the type locality of S. caligocephalus. Furthermore, whereas S. borneensis appears to be a lowland tropical forest species (highest known elevation ca. 56 m at the type locality; Kaiser et al. 2018a), S. caligocephalus occupies montane forest habitat at elevations well above 1000 m. The lowest elevation for which we have found a published sighting (Malkmus et al. 2002) is 1370 m, at the locality where the paratype was found. Stegonotus muelleri (n = 13 ♀, 19 ³) is from the south-central Philippine Islands and differs by scale counts of V = 217–241 (t = 5.24, P t = 7.74, P S. muelleri is on the island of Mindanao, ca. 1000 km by air from the type locality of S. caligocephalus . Description of the holotype (FMNH 251054)—metrics (in mm) and pholidosis. An adult female; length 1071 SVL + 188 TL = 1259 TTL, TL 21% of TTL; head broad, distinct from body; snout rounded in dorsal view, angled in lateral view, mouth subterminal. Rostral character state gull wing + (Fig. 4A, B). Internasals shorter than wide, with SSR = 0.25. Prefrontal width 2/3 of prefrontal length, prefrontal area about three times the area of the internasals; HSR = 0.31. Frontal pentagonal with well-formed corners and a slightly concave anterior suture; AE lies at the same level as the anterior edge of the frontal; FPR = 0.81 (Fig. 4A); PF Nasal two-thirds as tall as wide; naris half the length and the same width as the nasal; loreal about twice as long as wide; two preoculars with the lower half the area of the upper. Nine supralabials; SL4–5 touching the eye, SL5 40% larger than SL4; relative areas of supralabials 7 = 6> 8> 5> 9 = 4> 3> 2 = 1, SL 2 is rectangular whereas SL1 is triangular (Fig. 4B, B’). Eye length two-thirds of eye-naris distance; pupil oval; internarial distance 60% of interorbital distance. Ten infralabials; IL1–5 contacting anterior genials, with two-thirds of the medial border of IL 5 in contact with the anterior genial; three gulars separating the posterior genial from the anterior-most gastrostege; length of mental groove one-third of ventral head length (VHR = 0.38; Fig. 4 C’). Dorsals in 17-17-15 rows, 214 ventrals, cloacal plate entire, 56 paired subcaudals, SCR ♀ = 0.21. Description of the holotype (FMNH 251054)—coloration in preservative (27 years after collection). Dorsum Tawny Olive (Color 17) with some dark spots on lateral edge of a few rows of dorsal scales, head Grayish Olive (273) with scattered lighter areas in Olive Gray (265). The supralabials and infralabials are Pale Buff (1) with mottled areas of Drab-Gray (256) (Fig. 3A, 4A, B). The venter is Pale Horn (11) with dark areas on the anterior edge of the ventral scales and a dark “dot” on the lateral edge (Burnt Sienna, 38); the anterior one-third of the subcaudals are Burnt Sienna (38), creating a dark tail (Figs. 3B). Key data for the paratype—metrics (in mm) and pholidosis. An adult female (Fig. 5), 965 mm SVL + 191 mm TL = 1156 mm TTL, TL = 17% of TTL. V ♀ = 218, SC ♀ = 62, SCR ♀ = 0.22, D = 17-17-15, SL E = 4+5, SL = 9, IL = 10, IL G = 5. Coloration in life. Based on a color analysis of the images in Fig. 6, which have different lighting, we estimated the coloration in life as follows. The dorsal area of the head is Dark Grayish Brown (284) with some scattered Smoky White (261) spots. The color intensity fades laterally, and a lighter brown with elements of Cinnamon-Drab (50) and Beige (254) dominates the supralabial area. The dorsal coloration of the body is in tones of Mars Brown (25) and much lighter than the head, fading in the area where dorsal and ventral scales meet to a light shade of Light Russet Vinaceous (246). This faded color is also visible on the anterolateral margins of each ventral scale. Natural history. Whereas during several trips to the Mount Kinabalu area we have never encountered S. caligocephalus, we here provide information obtained from the literature and the field notes of colleagues. The species has only been encountered in forested areas of Crocker Range and Mount Kinabalu National Park above 1300 m, which consists mainly of montane oak-conifer rainforest (Inger & Tan 1996). Whereas there is a consensus that the species is generally nocturnal (Malkmus 1989, 1991, 1992, 1996; Manthey & Grossmann 1997; Max Dehling, pers. comm.; Tom Charlton, pers. comm.), there is some disagreement over the movement of this snake. However, Manthey & Grossmann (1997) consider this species to be an exclusively ground-dwelling form, Malkmus (1994) reported on some arboreal activity. In terms of feeding ecology, Malkmus (1994) reported on a predatory attempt on a gecko (Cyrtodactylus baluensis) in the only recorded feeding interaction. Similar species. The species could, in principle, be confused with three similarly colored species (Stuebing et al. 2014). Lycodon albofuscus 4 has keeled scales, is more slender, and its lowland habitat make it unlikely that this species occurs in sympatry with S. caligocephalus. On Borneo, older individuals of Lycodon subcinctus may have lost the characteristic light bands of younger snakes and may present an overall body coloration similar to S. caligocephalus. As is the case with L. albofuscus, the range of L. subcinctus may not extend into the higher elevations (above 1000 m) where S. caligocephalus is found. 2004; Wallach et al. 2014) but according to Das & Yaakob (2007), Das (2012), and the most recent available phylogenetic information (Figueroa et al. 2016; Wostl et al. 2017) the genus Lepturophis should be synonymized with Lycodon and this species is therefore treated as Lycodon albofuscus here. Important warning for field encounters. The snakes with which S. caligocephalus are most likely to be confused in the field are younger individuals of the venomous Sunda spitting cobra, Naja sumatrana, which actually appears to be more commonly encountered in the proximity of human habitations than S. caligocephalus. Both species are very similar in color and habits and it is difficult to tell them apart at a glance, especially in the dim cone of a flashlight by night. However, once engaged a spitting cobra will take up its characteristic threat posture with its head and body raised off the ground. In addition, spitting cobras are known to hiss dramatically when threatened. Needless to say, while the venom delivered by the bite of spitting cobras as well as the toxungen 5 delivered to the eyes are dangerous to humans, these snakes are quite harmless when left undisturbed. In general, great care must be taken when encountering any medium-sized dark snake in Borneo. Etymology. The species name caligocephalus is a compound word derived from the Latin caligo, with meanings including dark(ness), out of sight, fog, and the Greek kephalos (κεϕαλοζ) meaning head. We deliberately select a mixed-language name given that this name is designed to have mixed morphological and metaphorical meanings. The species name first of all references the darker head color in this species. Secondly, the dark, looming shape of Mount Kinabalu, Southeast Asia’s tallest mountain and the montane home of S. caligocephalus, is a dramatic, head-like massif, and we wish to remind people that mountain regions are wonderful places to explore and preserve nature.

Ablabes greineri Bleeker, 1860a:43 Taxonomic status. Junior synonym of S. modestus. Synonyms. None. Original name. Ablabes Greineri Bleeker 1860a:43. Pieter Bleeker (1819���1878; Fig. 3G) was a medical officer in the Dutch East Indies (now Indonesia) with a keen interest in natural history. He became particularly well known for his ichthyological collections and authored over 500 publications (Bleeker 1877). He named this species in honor of the physician C.G.C.F. Greiner, Health Officer 2 nd Class (Bleeker 1860a), who served alongside Bleeker as a physician in the Dutch military. The species description was presented in Dutch. The undated photograph of Bleeker (Fig. 3G; licensed under CC-BY-3.0) is from the Holthuis Collection, RMNH. Holotype. BMNH 1946.1.13.74, formerly BMNH 63.12.4.21 9 (Fig. 9; Table 1), an adult male. Type locality. ���Amboina��� [Ambon Island, Maluku Province, Indonesia]. Collection. His position with the Royal Netherlands East Indies army demanded that Bleeker���s main area of activity remained near Batavia (now Jakarta), the nexus of the Dutch power structure in what is now Indonesia (Heiningen 2010). However, his influential position allowed him to establish an excellent supplier network to obtain natural history specimens from throughout the Dutch realm in Southeast Asia. In late 1855, Bleeker accompanied the then-Governor-General of the Dutch East Indies, Albertus Duymaer van Twist (1809���1887) on a tour of northern Sulawesi and the central Moluccas, and this is the only time during his tenure in the region, outside of his regular posting on Java, when he could have personally collected specimens. The Governor-General���s posse stayed on Ambon for a week in early October 1855 (Bleeker 1856). Based on this information, the specimen was most likely collected between 2���9 October 1855. 9. Original BMNH accession numbers were composed of four numbers (e.g., 00.00.00.00) the first three of which indicated the year, month, and day of accession. Thus, the original number of the Ablabes greineri holotype (BMNH 63.12.4.21) indicates that the specimen was accessioned on 4 December 1863. In the 20 th Century, four-digit prefixes were used for the year (e.g., 1912.00.00.00). During the Second World War, the BMNH relocated type specimens preserved in alcohol to prevent their loss from air attacks. When specimens were returned to the collection after the war, they were re-accessioned into the collection with new accession numbers, such as in the case of snake specimens with a 1946 prefix (Long 1981). Key characteristics of the holotype. O (552) mm SVL + O (162) mm TL = O (714) mm TTL. V ♂ = O (206), SC ♂ = O (87), SCR ♂ = O (0.30), D = O (17-17-15), SL E = 3+4 (3+4), SL = 7 (7), IL = O (8), IL G = O (4). Bleeker (1860) commented that the body length was 4.5 times the length of the tail, which would indicate a ratio of SVL to TTL of 0.22. Using our length measurements to calculate this ratio, the result is essentially identical (0.23). Key characteristics of the species. See the account of S. modestus above. Comments. We believe that circumstantial evidence indeed points to Bleeker personally collecting this specimen during the 1855 sojourn, as opposed to receiving it subsequently through his supplier network. In an earlier publication (Bleeker 1856:63) listed among the 20 snakes species he identified for Ambon ��� Lycodon modestum Schl. ��� It appears that during his initial sorting of specimens, Bleeker considered this form conspecific with S. modestus but later changed his mind and erected a new species for the specimen from his own collection. Thus, the specimen was already in Bleeker���s possession in time for the 1856 publication, but the description under a new name occurred only four years later., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 19-20, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Bleeker, P.

The original description states that TL represents 22% of TTL in the holotype. This means that SVL represents 78%, and TL can be calculated as 221 mm. We applied the same calculation to the paratype. 20. This value was established right at the neck, and we confirmed this count. However, within one head length posteriorly, the number of dorsal scale rows reduces to 17. The author noted that this reduction occurred ���before level of twelfth ventral.��� The same generally applies to species of Stegonotus, with the possible exception of S. muelleri. Collection. All type specimens were collected by Stephen Richards (South Australian Museum, Adelaide, South Australia), Burhan Tjaturadi (Sanata Dharma University, Yogyakarta, Indonesia), and Keliopas Krey (University of Papua, Manokwari, Indonesian New Guinea) in June 2005.

Comment. In their description of S. iridis, Ruane et al. (2017) listed one specimen as possibly female. For the purposes of our discussion, we considered it unsexed and omitted it from parts of the analysis where sexual dimorphism could play a role (i.e., for values of V, SC, and SCR)., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 54-56, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575

Lycodon magnus Meyer, 1874:136 Taxonomic status. Junior synonym of S. cucullatus. The only certain type specimen was destroyed. Synonyms. None. Original name. Lycodon magnus Meyer, 1874:136. Adolf Bernhard Meyer (1840���1911; Fig. 3L) was a German naturalist and anthropologist, who conducted an expedition to the Malay Archipelago and Papuasia in the early 1870s (Meyer 1873a, b, 1875). Upon his return, he served as the director of the K��nigliches Naturhistorisches Museum (now Senckenberg Naturhistorische Sammlungen, Museum f��r Tierkunde) in Dresden, Germany from 1874���1906. Meyer���s portrait (Fig. 3L; public domain) is from ca. 1880. The species description was presented in German. We assume that the species epithet magnus [great] was selected to reflect the size of the specimens available for study. Syntypes. The assessment of type material for S. magnus is not straightforward. It is clear from the species description that Meyer used a single specimen to report scale characteristics, including counts. However, in the last sentence of the text, after detailing aspects of color and pattern in the species, he stated, ���[e]inige Exemplare theilweise geringelt��� [some specimens partly banded]. This statement shows that the specimen series available to Meyer included several specimens, and presumably more than two. The Dresden type catalog of Sch��z (1929), however, listed only a single specimen of L. magnus (MTKD 573), as does the collection���s specimen ledger. It is therefore reasonable to assume that some of the type material was exchanged to other museums. This specimen, along with most of the remaining alcoholic specimens and the city itself, were destroyed during the night of 13���14 February 1945 in the Allied bombing of Dresden. We were able to locate only one contemporary specimen (ZMB 8794; Fig. 15) whose catalog entry lists it as L. magnus with a notation that it is a type specimen (a notation reflected by a label affixed to the jar), and whose characteristics are close to those of MTKD 573 (Table 1). According to the catalog information, this specimen was also collected by Meyer. The collection locality for the ZMB specimen, however, is flagged with a question mark in the specimen ledger: it is Rubi, a locality 250 km distant at the southern extreme of Cenderawasih Bay (3.3897��S, 135.3179��E). No other specimen from Biak Island we have been able to examine conforms to the middorsal count of 19 reported by Meyer. At this point, we are unable to resolve the conundrum surrounding the type specimens of L. magnus. Nevertheless, in the interest of clarity and stability, we hereby designate MTKD 573, the specimen whose characteristics Meyer (1874) used to describe the scale counts of his new species, as the lectotype of L. magnus (Code, Article 74.7). If and when the need arises to designate a neotype of this species the characteristics of this specimen must therefore inform the selection of a neotype (ICZN 1999; Article 75). Type locality. ���Neu-Guinea, Mysore.��� The locality here identified by Meyer (1874) by the single name ���Mysore��� actually comprises a complex of two islands separated by only a narrow channel, as described by Meyer (1873b). However, Meyer (1873a, b) decided to use the single name ���Mysore��� in his collection records for these islands, and he used ���Mysore��� and ���Willem Schoutens Insel ��� in popular accounts of his journeys (Meyer 1873a, b). The island in the east is called Supiori (also Sipiori on historic Dutch maps or Kordo on historic German maps), and the port of Korido on Supiori was where Meyer made landfall (Meyer 1873a, b; Wichmann 1910). The second, western island, Biak (or Wiak), was at the time considered to be composed of two islands by some, Biak itself and the region around its northernmost tip (called Meossoir on historic Dutch maps, or Misory on historic German maps; Meyer 1873a, b, 1875). Even though Meyer (1887) listed ���Kordo��� as one of his collecting localities, this was done in reference to L. cucullatus, with which he had synonymized L. magnus. Meyer���s locality was later restricted under the name L. magnus by Sch��z (1929), who included the town name ���Kordo��� [Korido] and added information found in the MTKD specimen ledger. We therefore restrict the type locality of L. magnus to the area around Korido, Supiori Island, Papua Province, Indonesia (ca. 0.8178��S, 135.5643��E). Collection. According to Meyer (1875) and Wichmann (1910), Meyer arrived in Korido on 25 March 1873 and departed on 5 April. The specimens must therefore have been collected between those dates.

Stegonotus lividus (M��ller in Dum��ril et al., 1854:381) n. comb. Taxonomic status. Lycodon lividum has heretofore been considered as a synonym of S. modestus. With the restriction of that species to some of the islands in the central Moluccas, and given the absence of the neck band, smaller adult size, and the much lower SC count in L. lividum, we hereby remove this species from the synonymy of S. modestus. As a member of the genus Stegonotus, the species name needs to be emended to lividus. This population therefore takes the name Stegonotus lividus n. comb. Synonyms. None. Original name. Lycodon lividum S. M��ller in Dum��ril et al., 1854:381. The Latin term lividus, meaning ���bluish metal-colored��� or ���lead-colored,��� was likely selected to reflect the coloration of the syntypes. The species description was presented in French. Syntypes. RMNH. RENA 325 A (Fig. 6 A���E; Table 1) and 325B (Fig. 6 F���H), two specimens, both likely adult females. 7. In the language of Biak islanders the suffix ���ri is added as an emphasis in spoken communication. The spoken word dore-ri means ���bay.��� Considering the geographical perspective from Biak Island, this dore-ri was not just any bay, but specifically the largest bay on the nearby mainland, whose small islands (such as Mansinam) had been settled by people from Biak. Unfortunately, this means that the colonial terms Dorery Bay or H��vre Dorey translate to ���bay bay,��� a duplication similar to the Indonesian-Portuguese construct for the country name Timor-Leste, meaning ���east-east.��� In the interest of retaining a unique name for the bay on which the city of Manokwari lies, we believe that combining the traditional Biak name doreri with the English noun ���bay��� works best, the nonsensical duplication notwithstanding. Thus, this locality should prop- erly be known as Doreri Bay. 8. There appears to be some confusion over the year when this publication appeared. The information was published inPart 1 of Volume 2 of the French naval officer Louis Isidore Duperrey's (1786���1865) series describing the findings of some of the voyages he captained. The publication year 1830 is printed on the frontispiece. Chapter IX was authored by Lesson and, according to the meticulous research by Sherborn & Woodward (1901, 1906) the volume was released on 12 June 1830. Type locality. The species was discovered on ���l�����le de Pulo-Samao��� [Semau Island, East Nusa Tenggara Province, Indonesia]. Collectors. Exploration of Timor Island by the Dutch Commissie was not limited to the area around Kupang in the southwest but included several sojourns into the interior as well as to the nearby islands of Semau and Kambing. The collecting was done by M��ller and Pieter van Oort (1804���1834; Fig. 3F), under the direction and with the participation of Heinrich Macklot (1799���1832). Specimens in the RMNH collected at this time usually include the notation ��� MM,��� indicating specimens collected by M��ller and Macklot. Even though we have not been able to find specific dates for a visit to Semau by the Commissie team, elimination of dates during which collections were made elsewhere allow us to state that the visit to the islands must have occurred in mid-1829 (see dates provided by Steenis-Kruseman 1950). The image of Van Oort (Fig. 3F; public domain) is a self-portrait originally colored in red chalk from the collection of the Centraal Museum in Utrecht, The Netherlands. Key characteristics of the syntypes. RMNH. RENA 325 A: 420 (489) mm SVL + 140 (118) mm TL = 560 (607) mm TTL.

There are only two specimens of Stegonotus from Semau in museum collections, the two syntypes of S. lividus. As a consequence, it is not possible to adequately characterize the species. Values for V and SC appear to be near 200 and 70, respectively, with tail length around one quarter of the total length of the animal based on SCR values, and D = 17-17-15. Other consistent scale counts include SL = 7, SL E = 3+4, IL = 9, and IL G = 4. Comments. In their original description, Dum��ril et al. (1854) listed scale counts for a single specimen, and the listed numbers conform almost exactly to our counts for RMNH.RENA 325A. However, near the end of their description, the authors stated that ���Le Mus��e de Leyde possede les seuls individus qu���il y ait recueillis et que nous avons ��tudi��s.��� [The Rijksmuseum van Natuurlijke Historie has the only specimens that M��ller collected and which we have studied.] Use of the plural ���les seuls individus��� clearly indicates that more than one specimen was used to compile the species description, even if the numbers were provided only for one. In order to avoid any confusion over which specimen was used for the species description and to enhance the stability of the species, we hereby designate RMNH.RENA 325A as the lectotype of S. lividus, rendering RMNH.RENA 325B as a paralectotype (Code, Article 74.7). Stegonotus lividus was listed in the synonymy of S. modestus by McDowell (1972), but McDowell flagged this synonymy by adding a question mark in front of the species name���a question mark that our new data show to be justified. Iskandar & Colijn (2002) considered the possibility that S. lividus could be a synonym of S. florensis, but this was dispelled by de Lang (2011) based on a series of comparative characteristics. The latter considered S. lividus to potentially be a synonym of S. modestus and included that species, based on the S. lividus records, among his category of doubtful records for the Lesser Sunda Islands. De Lang (2011) also raised the issue that the locality information for the type specimens of S. lividus could have been ���mixed up somewhere in the past,��� given that the collector Salomon M��ller traveled to Ambon, where S. modestus occurs but did not specifically list these specimens in his account of his travels (M��ller 1857). However, none of the descriptions of S. lividus include mention of the characteristic neck band of S. modestus and additional morphological differences exist and allow differentiation of S. lividus and S. modestus., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 14-16, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Dumeril, A. - M. - C., Bibron, G. & Dumeril, A. - H. - A.

Stegonotus florensis (de Rooij, 1917:110) Taxonomic status. Valid. Synonyms. Stegonotus sutteri Forcart, 1953. Original name. Lycodon florensis de Rooij, 1917:110. Petronella Johanna “Nelly” de Rooij (1883–1964; Fig. 17I) was a Dutch zoologist and, from 1907–1922, the curator of the collection in the Zoological Museum at the University of Amsterdam. During this time, de Rooij compiled two important volumes, presenting the first comprehensive descriptions of the reptiles in the Indo-Australian Archipelago (de Rooij 1915, 1917). It is noteworthy that during her career de Rooij experienced heavy discrimination by policies then in place that discriminated against women (Beolens et al. 2011), first against her academic advance, which required her to complete her doctorate (earned in 1907) in Zürich, Switzerland, and later in her position as curator in Amsterdam, from which she elected to resign in 1922 at the age of only 39 due to discriminatory administrative reforms (Adler 2007). Unfortunately, this effectively ended de Rooij’s research career. De Rooij’s portrait (Fig. 17I) is from the archives of the RMNH. The species name reflects the type locality, Flores Island. The species description was presented in English. Holotype. ZMA 11080, an adult female (Fig. 26; Table 1). The specimen is now housed in the Naturalis Biodiversity Center, Leiden, The Netherlands. The specimen was figured by de Rooij (1917: Figs. 46, 47). Type locality. “ Flores (near Kotting)” [Koting, ca. 3 km S Maumere, Flores Island, East Nusa Tenggara Province, Indonesia, ca. 8.68°S, 122.19°E]. The catalog entry for the specimen in the ZMA collection reads “ Flores, Omgeving van Kotting, Maumeri-Rivier” [Flores, vicinity of Koting, Maumere River], and in the Koting area there are numerous small tributaries that drain into one larger riverbed that runs through the city of Maumere on the north coast of Flores. Collection. According to the catalog entry in the ZMA collection, the specimen was collected by G.A.J. van de Sande, a member of the Koninklijk Instituut voor de Taal-, Land- en Volkenkunde van Nederlandsch-Indië [Royal Institute for Linguistics, Geography, and Ethnology of the Dutch Indies], who died in 1909 (Anonymous 1911). Key characteristics of the holotype. 456 (447) mm SVL + 112 (109) mm TL = 568 (556) mm TTL. V ♀ = 218 (217), SC ♀ = 66 (65), SCR ♀ = 0.23 (0.23), D = O-21-O (21-21-19), SL E = 3+4+5 (3+4+5), SL = 9R 8L (9R 8L), IL = O (10), IL G = O (5). Other than S. heterurus and S. sutteri (see below), this species is the only other Stegonotus with unpaired subcaudal scales. Key characteristics of the species. We were only able to find and examine two specimens of this form from Flores Island (the terra typica) in collections accessible to us, the female holotype and a male specimen in the Western Australian Museum, Perth, Australia (WAM 104606) collected in 1991. The dearth of specimens in collections makes any assessment of the characteristics of S. florensis at the species level tenuous at best. Characteristics include V ♀ = 217, V ♂ = 230; SC ♀ = 65, SC ♂ = 82; SCR ♀ = 0.23, SCR ♂ = 0.26; D = 21-21-19; SL E = 3+4+5; SL = 8 or 9; IL = 9 or 10; IL G = 5. It appears that sexual dimorphism in the numbers of ventral and subcaudal scales might exist, with males possessing higher numbers of both and a relatively longer tail. However, given the low sample size this is speculative. Comments. Based on x-ray images, Forcart (1954) noted that L. florensis did not possess the characteristic separation dividing the maxillary teeth into two sets, with some enlarged teeth anterior to the gap. Instead, he considered the maxillary dentition of L. florensis to reflect the characteristics used by Duméril et al. (1854) to the genus Stegonotus. It should be noted that this specimens presents with an aberration in the set of supralabial scales on both sides of the head. Unrecognized by de Rooij (1917) and drawn incorrectly in her line drawing of the right lateral side of the head, SL5 appears to be divided into two parts. While this does not change the overall supralabial count, it influences whether SL5 contacts the eye or not. In the second specimen of S. florensis we examined, as well as in all specimens of the likely related S. sutteri (see below), SL5 is a single, large supralabial. De Lang (2011) stated that specimens of S. florensis he studied varied in SL E, with some specimens showing values of 3+4 and 4+ 5 in addition to the diagnostic 3+4+5. We cannot confirm or deny this, but none of the specimens of S. florensis (as well as of S. sutteri, see below) we examined had conditions of SL E other than 3+4+5. All other data listed by de Lang (2011) conform to our concept of the species S. florensis., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 46-47, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["de Rooij, N.

Coluber holochrous G��nther, 1863a:59 Taxonomic status. Junior synonym of S. modestus. The species holochrous is the type species of the genus Lielaphis (described as a subgenus of Colubri). Synonyms. None. Original name. Coluber holochrous G��nther, 1863a:59. Albert G��nther (1830���1914; Fig. 3K) was a German zoologist, whose influential position as Keeper of Zoology (head of the zoology department) at the British Museum of Natural History (now The Natural History Museum) led him to become one of the most productive reptile taxonomists of all time (Uetz 2010). In his species definition, of C. holochrous G��nther (1863a) specified that the body coloration was ���uniform brownish grey.��� We therefore assume that the species epithet (the Greek prefix holoplus the suffix chro[m]us = all one color) was chosen to reflect this uniform coloration. The species description was presented in English. The photographic portrait of G��nther (Fig. 3K; public domain) was taken in ca. 1900 and is housed in the collection of the BMNH. Holotype. BMNH 1946.1.11.40 (Fig. 12; Table 1), formerly BMNH 63.3.28.31, an adult male, illustrated by G��nther (1863a: Fig. 11). Type locality. ���North Ceram��� [northern Seram Island, Maluku Province, Indonesia]. Collection. In Boulenger���s (1893) Catalogue, the specimen is listed as the ��� Type of L [ielaphis] holochrous,��� and it is implied that it was collected by Pieter Bleeker (although the specific designation of ���C.��� for ���collector��� used elsewhere in Boulenger���s listing is not printed in this case). However, this could merely indicate that Bleeker had shipped the specimen to London. Bleeker (1856) reported that his party left Ambon for the Banda Islands on 11 October 1855 and made a stop of only a few hours at Amahai on the south coast of Seram. Therefore, Bleeker would have been unable to collect this specimen himself in northern Seram, and it was most likely sent to him by someone in his network of suppliers, including Rosenberg, who is known to have collected there. Key characteristics of the holotype. O (915) mm SVL + O (277) mm TL = 43 in [1092 mm] (1192) mm TTL. V ♂ = 206 (206), SC ♂ = 87 (87), SCR ♂ = 0.30 (0.30), D = O (17-17-15), SL E = 3+4 (3+4), SL = 7 (7), IL = 8 (8), IL G = 5 (4). We believe that G��nther must have counted the fifth infralabial scale as touching the anterior genial, even though that scale���s anteromedial corner does not touch the genial, but is positioned diagonally opposite. Since we do not believe that this character state has changed during preservation, we believe it to be G��nther���s error. Key characteristics of the species. See the account of S. modestus above. Comments. Following the description of this species, G��nther (1863a) discussed the division of Colubri 10 into subgenera, listing Coluber, Elaphis, Cynophis, Spilotes, and Coryphodon, and referencing his Catalogue of Colubrine Snakes (G��nther 1858). He noted that the species he described under the name holochrous did not fit into any of these subgenera and proposed the name Lielaphis as a sixth group, defined in the text, to accommodate C. holochrous as the type species and referring Spilotes samarensis to this new subgenus. His paper on new reptile records from Seram therefore not only featured the description of the species C. holochrous, it also originated the genus-level name Lielaphis., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 22-25, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Gunther, A.

Stegonotus keyensis (Doria, 1874:351) n. comb. Taxonomic status. Lycodon keyensis has heretofore been considered as a synonym of S. cucullatus. Based on lower ventral and subcaudal counts, a much shorter tail relative to overall body size as indicated by SCR values, and a distance of over 500 km from the type locality of S. cucullatus across the Bird���s Head Peninsula of West Papua and the Seram Sea, we hereby remove this species from the synonymy of S. cucullatus. The Kei Island populations of Stegonotus therefore take the name Stegonotus keyensis n. comb. Synonyms. None. Original name. Lycodon keyensis Doria, 1874:351. The species was described by Giacomo Doria (see above), who presented the description in Italian. It is named for the Kei Islands, its geographic origin. Holotype. MSNG 7521 (Fig. 19; Table 1), most likely an adult male (see below). Type locality. ���Isole Kei��� [the Kei Islands, Maluku Province, Indonesia]. Just as in the case of the Aru Islands, the locality ���Isole Kei��� is not specific enough to determine on which of the Kei Islands the specimen was collected. A description of Beccari���s visit to these islands, supported by Beccari���s own cited letters to Doria (Gigliolo 1874), shows that Beccari spent most of his time on Dullah and Kei Kecil, after having been shipwrecked on the voyage from Aru on Kei Besar (Anonymous 2018a). It is therefore not possible to restrict the type locality further. Collector. The specimen was collected by Odoardo Beccari (see above), who arrived in the Kei Islands on 6 July 1872 and departed from the main town of Tual on Dullah for Ambon on 4 September 1872. It was therefore collected between those dates. Key characteristics of the holotype. O (651) mm SVL + 170 (164) mm TL = 800 (815) mm TTL. V ♂ = 200 (200), SC ♂ = 73 (73), SCR ♂ = O (0.27), D = O-17-O (17-17-15), SL E = 4+5 (4+5), SL = 9 (9), IL = O (9L 10R), IL G = O (5). Based on the SC count of 73 and then non-overlapping sexual dimorphism in SC numbers (see below), we believe this specimen to be a male and treat it as such. Key characteristics of the species. We were able to examine seven specimens of S. keyensis that were collected on one of the Kei Islands. Of these, two females were collected on Dullah, two males on Kei Besar, one male on Taam, and two (1 ♀, 1 ♂), including the male holotype, were collected at unspecified localities. Characteristics include V ♀ = 188���200 (193 �� 6.1), V ♂ = 200���207 (204 �� 3.5); SC ♀ = 59���66 (63 �� 3.5), SC ♂ = 70���80 (74 �� 5.1); SCR ♀ = 0.25, SCR ♂ = 0.27; D = 17-17-15 (100%); SL E = 4+5 (n = 6, 86%) or 3+4 (n = 1, 14%); SL = 8 (n = 5, 71%) or 9 (n = 2, 29%); IL = 8 (n = 2, 29%), 9 (n = 3, 43%), or 10 (n = 2, 29%); IL G = 5. The species shows sexual dimorphism with respect to the numbers of both ventral and subcaudal scales. This difference does not result in obviously different SCR values, but this may be a statistical artifact of comparing ratios when sample sizes are small. Roux (1910) reported on two specimens (no numbers provided), one from Dullah and the other from Kei Besar. Both of these fit within the parameters for S. keyensis, as reported above. Comments. The set of infralabial scales on the right side of the holotype presents one unusual feature, a fragmentation of IL9 into two small, shallow scales, each of which we counted to arrive at our count of IL = 10 L. Boulenger (1893) synonymized the species with S. cucullatus, but Roux (1910) considered it more likely that the synonymy should be with S. modestus. We have found no evidence for the occurrence of either S. cucullatus or S. modestus in the Kei Islands. The existence of the species has so far only been confirmed for Dullah and Kei Besar using voucher specimens, but it is likely that it occurs on other nearby islands as well., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 35-36, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Doria, G.

The species epithet honors Nelly de Rooij (Fig. 17I), who described S. florensis (see above). The species description was presented in English. Type specimens. Holotype: MZB Ophi.3288 (Fig. 32 A���E; Ruane et al. 2017: Fig. 6), an adult male (Table 1). Paratypes: MZB Ophi.3293 (Fig. 32 F���H), listed as possibly female. SAMA R70467 (Fig. 32 I���K), listed as possibly female. Type localities. All type specimens were collected in Raja Ampat Regency, West Papua Province, Indonesia.

Paratypes: MZB Ophi.3293, same data as the holotype; SAMA R70467, Warinkabom, Batanta Island, elev. 50 m (ca. 0.8369��S, 130.72��E). Collection. All type specimens were collected by Stephen Richards, Burhan Tjaturadi, and Keliopas Krey between 5 and 28 June 2005. Key characteristics of the type specimens.

(2) Paratype, MZB Ophi.3293: 450 mm SVL + 168+ mm TL = 618+ mm TTL. V ? = 178, SC ? = O, SCR ? = O, D = O-17-O, SL E = O, SL = 7, IL = 9, IL G = O. (3) Paratype, SAMA R70467: 290 mm SVL + 108 mm TL = 398 mm TTL. V ? = 178, SC ? = 90, SCR ? = 0.34, D = O-17-O, SL E = O, SL = 7, IL = 8, IL G = O. Key characteristics of the species. According to their specimen list, Ruane et al. (2017: Appendix) included four specimens (three types, one without type status) of S. derooijae in their analysis. Those the authors considered as possibly female we considered as unsexed for the purposes of our analysis and lumped them into a questionable category for the potentially sexually dimorphic values of V, SC, and SCR, as indicated by a subscripted question mark (?). Of the examined series, one unsexed specimen was collected on Batanta, one male and one unsexed specimen on Salawati, and one unsexed specimen on Waigeo. Characteristics include V ? = 178���197 (184 �� 11.0), V ♂ = 181; SC ? = 90���91, SC ♂ = 94; SCR ? = 0.33, SCR ♂ = 0.34; D = O-17-O (100%); SL E most likely 3+4; SL = 7 (n = 3, 75%) or 9 (n = 1, 25%); IL = 8 (n = 2, 50%) or 9 (n = 2, 50%); IL G most likely 5. The range in ventral scales gives us pause, as it is large and with a very high standard deviation. In other species of Stegonotus, standard deviations for ventral scales range from 4���8 scales, and 11 appears to be very high, even if two sexes are lumped together in this data set. Comment.

Coronella rosenbergii Bleeker, 1860b:37 Taxonomic status. Junior synonym of S. modestus. Synonyms. None. Original name. Coronella Rosenbergii Bleeker 1860b:37. This species was named for the German naturalist Hermann von Rosenberg (1817���1888; Fig. 3H), who made an herpetological collection along the southern coast of Seram Island. Rosenberg was originally a cartographer and the Acting Civil Administrator of southern Seram (Bleeker 1860b; Steenis-Kruseman 1950) but his interest in ornithology connected him to Hermann Schlegel at the RMNH in Leiden. The species description was presented in Dutch. Rosenberg���s photograph (Fig. 3H; public domain) was taken by the photographer Conrad Spamer in 1882. Holotype. RMNH. RENA 4066 (Fig. 10; Table 1), an adult male. Type locality. ���Paulohi, Ceram, Molukschen Archipel��� [Seram Island, Maluku Province, Indonesia]. Bleeker (1860b) stated specifically that he considered this to be the first collection of reptiles from the southern coast of Seram. The locality name refers to a region in the south-central area of Seram inhabited by speakers of Paulohi, a rare Malayo-Polynesian language (Stresemann 1927; Wurm 2007). The most likely location for a collection in the mid-1800s is near the settlement of Amahai (ca. 3.3416��S, 128.9235��E), a port facing Ambon, the main population center of the region, which Bleeker visited on 11 October 1855 (Bleeker 1856). Collection. The specimen was collected in southern Seram by Rosenberg, for whom the species was named. Rosenberg was stationed on Seram from 26 April 1859 ��� 17 December 1861 (Rosenberg 1867; Steenis-Kruseman 1950) and, during that time, must have collected for Bleeker, whom he most likely met in Batavia before his deployment. Bleeker���s species description was dated April 1860, which leads us to believe that the specimen was most likely collected during the second half of 1859. Key characteristics of the holotype. O (582) mm SVL + O (178) mm TL = O (760) mm TTL. V ♂ = O (203), SC ♂ = O (80), SCR ♂ = O (0.28), D = O (17-17-15), SL E = O (3+4), SL = 7 (7), IL = O (9), IL G = O (4). Bleeker (1860b) remarked that the tail was roughly one quarter the length of the entire body, which fits well with our measurements (TL/TTL = 0.23). Key characteristics of the species. See the account of S. modestus above. Comments. Bleeker (1860b) specifically mentioned that the specimen had ���een flaauwe gele dwarsche nekband��� [a faint yellow cross neckband], which is a key characteristic of S. modestus. In his treatment of Papua New Guinean Stegonotus, McDowell (1972) included a footnote below his account for S. modestus, in which he stated that ���Bleeker based his description [of C. rosenbergii] on two specimens,��� one from the museum in Leiden (RMNH 4066) and one from London (BMNH 1946.1.13.88). McDowell further opined that Boulenger���s (1893:367) listing of the latter as ���Type of C. rosenbergii ��� constituted a lectotype designation. We carefully read Bleeker���s (1860b) species description and found no indication that Bleeker had two specimens in hand when he described the species. Furthermore, whereas Bleeker���s type locality is very specific, the one provided by Boulenger (1893) for BMNH 1946.1.13.88 is vague, listing merely ���Ceram.��� Lastly, the original collection number of the BMNH specimen is 63.12.4.9, indicating that the specimen reached London with a shipment from Bleeker in 1863, three years after the original description was published. Our interpretation of the Code leads us to conclude that Boulenger���s (1893) notation that BMNH 1946.1.13.88 (formerly 63.12.4.9) should be considered a syntype of C. rosenbergii is not supported by evidence in the original description or from the specimen itself. We therefore disagree with McDowell (1972) and hereby invalidate the purported lectotype designation (Code, Article 74.2). There is but a single type specimen of C. rosenbergii, and it is the holotype in Leiden., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 20-21, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Bleeker, P.

Stegonotus dorsalis Werner, 1924:32 Taxonomic status. Wallach et al. (2014) listed S. dorsalis in the synonymy of S. diehli without further comment. Werner (1924) himself stated at the beginning of his description that he considered this species ���n��chstverwandt��� [sister species] to S. diehli but provided a definitive series of differentiating characteristics. Based on the understanding of Stegonotus we have gained by examining nearly 1500 museum specimens, we consider the characteristics differentiating S. dorsalis from S. diehli, in addition to the uncertain taxonomy of the latter, sufficient to uphold a taxonomic distinction at the species level. None of the well-defined taxa in the genus Stegonotus (S. batjanensis, S. guentheri, S. heterurus, S. keyensis, S. modestus, S. muelleri) display ventral scales of sexes combined with a range of 29 scales (179 in the holotype of S. diehli to 208 in the holotype of S. dorsalis), which already provides strong evidence for species-level distinction. Furthermore, differences include (features of S. diehli provided in parentheses) SL = 8 (7), SL E = 4+5 (3+4), and IL G = 5 (4). We therefore remove S. dorsalis from the synonymy of S. diehli. Synonyms. None. Original name. Stegonotus dorsalis Werner, 1924:32. Franz Werner (1867���1939; Fig. 17J) was an Austrian herpetologist and entomologist, as well as lecturer and professor at the Institute for Zoology at the University of Vienna from 1891���1933. It is noteworthy that Werner was initially unable to use specimens at the NMW for his research, having been barred by Franz Steindachner (1834���1919), the then-curator. However, after Steindachner���s death, these restrictions appear to have been loosened, as attested by Werner���s description of S. dorsalis. The undated portrait of Werner (Fig. 17J; public domain) was taken by the Viennese portrait photographer Albin Kob�� (1884���1963) and hangs in the office of the herpetology curator at the NMW. Holotype. NMW 14861 (Fig. 27; Table 1), an adult male. Type locality. Neither jar label nor specimen catalog entry provide any information regarding the type locality. The historic jar label states ���Fundort?��� [locality?], indicating that no information about the type locality appeared to be available at the time the specimen was accessioned into the collection. However, based on the specimens included in Werner���s (1924) account of snakes in the Vienna museum it becomes clear that the only possible origin for specimens of Stegonotus housed there is New Guinea. Furthermore, the only zoological collection in New Guinea that would have found its way exclusively into the Vienna museum was made by the anthropologist and explorer Rudolf P��ch (1870���1921; Fig. 17K), later a professor of anthropology at Vienna University, who spent several months in New Guinea in 1904 (28 July���25 November; P��ch 1907, 1908), and whose name is associated with the (falsely identified) specimen of ��� Stegonotus modestus ��� that Werner (1924) included in his account. Further research we conducted in the archives of the Vienna collection led to the discovery of historic specimen inventory slips indicating New Guinea as the collection locality, as well as letters from P��ch to the then-curator, Franz Steindachner, in which the former recounts some of his travels. In one of these letters, P��ch wrote that specimens that had been sent without any specific locality information (i.e., those merely listing New Guinea) were all collected at ���Monumbo, K��stenstrich von Potsdamhafen, Deutsch-Neu-Guinea��� [Monumbo, in the coastal region around Potsdamhafen, German New Guinea, now Papua New Guinea]. A notation in the margin of the letter reveals that one package of specimens from this area was indeed inventoried. Alas, modern maps and gazetteers of Papua New Guinea show neither Monumbo nor Potsdamhafen. German maps of the early 1900s and, specifically, one created by P��ch himself in accordance with the Deutscher Kolonialatlas [German colonial atlas] (see P��ch 1908), reveal that the location of Potsdamhafen was in a small bay across from Manam Island, Madang Province, Papua New Guinea (ca. 4.2280��S, 144.9333��E). P��ch���s map and text also show that he used the term ���Monumbo��� for both a New Guinean tribe and the mountains bordering Potsdamhafen on the landward side. P��ch made several excursions into and through these mountains and included some biological aspects of his surveys in his travelogue (P��ch 1908). The image of P��ch (Fig. 17K; licensed under CC-BY-SA-4.0) is from the photographic collection of the archives at the University of Vienna, Austria. Collection. The label affixed to the jar lists only the comment ���Coll.?��� [collector?], indicating that no information was available. The most likely scenario for the collection of the holotype of Stegonotus dorsalis is that P��ch encountered the snake on one of his forays into the interior during the months of August���November 1904. With no opportunity to specify a locality on these expeditions, and with a focus on anthropological research, P��ch could have grouped his collected zoological specimens and provided the general locality of Monumbo for any specimens from the area inland of Potsdamhafen. The type locality of S. dorsalis (see below) is ca. 160 km NW of the type locality of S. diehli, across the mountains of the Adelbert Range. Key characteristics of the holotype. 805 (805) mm SVL + 245 (245) mm TL = 1050 (1050) mm TTL. V ♂ = 208 (208), SC ♂ = 88 (88), SCR ♂ = 0.30 (0.30), D = O-15-O (15-15-15), SL E = 4+5 (4+5), SL = 8 (8), IL = O (10), IL G = O (5). Key characteristics of the species. With only a single specimen available, any species-level characterization must remain very general. It appears that S. dorsalis has a relatively high ventral count (V = 208) compared to other species with 15 middorsal scale rows (S. diehli, S. guentheri), whose counts reach only the mid-190s. Other characteristics include SL E = 4+5, IL G = 5, and a relatively high IL count (10). Comment. This species was not mentioned in the works of McDowell (1972) and Ruane et al.

Stegonotus heterurus Boulenger, 1893:367 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus heterurus Boulenger, 1893:367. George Albert Boulenger (1858���1937; Fig. 17E) was a highly prolific Belgian-British naturalist associated for most of his professional life with the British Museum of Natural History. The species name heterurus is a word of Greek origin, combining ���heteros��� [different] and ���oura��� [tail] in reference to the fact that the subcaudal scales in this species are not paired, the character state in all species of Stegonotus known at the time of Boulenger���s description. The species description was presented in English. The image of Boulenger (Fig. 17E; reproduced under license no. 5449 from the National Portrait Gallery, London, United Kingdom) was taken in 1917 by the British portrait photographer Walter Stoneman (1876���1958). Syntypes. BMNH 1946.1.14.91 (formerly BMNH 83.3.17.13), 1946.1.14.95 (formerly BMNH 77.2.24.19), and 1946.1.15.10 (formerly BMNH 79.10.31.7), adult males (Fig. 22). Type localities. The localities provided by Boulenger (1893) and in the specimen register at the BMNH for the type series of S. heterurus are, unfortunately, rather vague. Two specimens (BMNH 1946.1.14.95, 1946.1.15.10) are from ���Duke of York Id.��� [Duke of York Island, East New Britain Province, Papua New Guinea], whereas BMNH 1946.1.14.91 is from ��� New Britain ��� [the largest island in the Bismarck Archipelago, comprising East New Britain Province and West New Britain Province, Papua New Guinea]. Of these, Duke of York is the largest island of the Duke of York Islands, a group of relatively small islands (total land area 58 km 2), with maximum dimensions of 10 km in a north���south direction and 9 km in an east���west direction, and with a maximum elevation of ca. 110 m. In contrast, New Britain is a large (36,520 km 2) and topographically and ecologically diverse island (with a mountainous topography, especially in the eastern part of the island, featuring a highest elevation of nearly 2500 m), and can hardly be considered a ���locality��� in the strict sense. Collection. Boulenger (1893) listed the Duke of York syntypes (BMNH 1946.1.14.95, 1946.1.15.10) as having been collected by ���Rev. G. Brown,��� who can be identified as the Methodist missionary George Brown (1835���1917; Fig. 17F), a close friend of the novelist Robert Louis Stevenson of Treasure Island fame (Anonymous 2018b). After an extended stint in Samoa, Brown spent a little over five years (1875���81) in the Bismarck Archipelago, arriving on Duke of York on 15 August 1875 at Port Hunter on the northern tip of the island (Anonymous 2018b). Port Hunter provided the base of operations for expanding the territory of the mission to New Ireland and New Britain. The specimens of S. heterurus must have been collected during this 5-year period, but we have not been able to pinpoint a specific locality or date. The photograph of Brown (Fig. 17F; public domain) is the frontispiece of his autobiography (Brown 1908). The third syntype (BMNH 1946.1.14.91) was listed as having been received from the ���Museum Godeffroy,��� the collection of the Huguenot trader Johann Cesar VI Godeffroy (1813���1885) in Hamburg, Germany. The collection was established in 1861, and for the next two decades a variety of collectors were employed to expand its holdings. Only one of the known collectors, Franz H��bner (1846���1877), is listed as having specifically collected on New Britain (Evenhuis 2007) during the years 1875���1877 (Weidner 1967). During the museum���s operation, its curator Johann Schmeltz (1839���1909) compiled a series of sales catalogs, and it is likely that the specimen appeared in one of these catalogs and was purchased by the British Museum of Natural History. Key characteristics of the type specimens. (1) BMNH 1946.1.14.91: O (364) mm SVL + O (108) mm TL = O (472) mm TTL. V ♂ = 188 (186), SC ♂ = 82 (83), SCR ♂ = 0.30 (0.31), D = O-17-O (17-17-15), SL E = 3+4 (3+4), SL = 7 (7), IL = O (8L 9R), IL G = 4 (4). (2) BMNH 1946.1.14.95: O (393) mm SVL + O (89) mm TL =O (482) mm TTL. V ♂ = 178 (179), SC ♂ = 81 (80), SCR ♂ = 0.31 (0.31), D = O-17-O (17-17-15), SL E = 3+4 (3+4), SL = 7 (7), IL = O (9), IL G = 4 (4). (3) 1946.1.15.10: 405 (477) mm SVL + 135 (135) mm TL = 540 (612) mm TTL. V ♂ = 182 (181), SC ♂ = 75 (76), SCR ♂ = 0.29 (0.30), D = O-17-O (17-17-15), SL E = 3+4 (3+4), SL = 9 (7), IL = O (O), IL G = 4 (4). It should be noted that the subcaudal counts in this species refer to subcaudal scales that span the entire width of the tail (i.e., unpaired subcaudals). Key characteristics of the species. We have been able to examine 19 specimens of S. heterurus. Of these, 11 (2 ♀♀, 6 ♂♂, 3 unsexed) were collected on New Britain, six on New Ireland (1 ♀, 5 ♂♂), and two on Duke of York (2 ♂♂). Characteristics include V ♀ = 183���193 (189 �� 5.1), V ♂ = 179���198 (188 �� 5.2); SC ♀ = 83���93 (89 �� 5.5), SC ♂ = 76���88 (82 �� 3.9); SCR ♀ = 0.32, SCR ♂ = 0.30; D = 17-17-15 (100%); SL E = 3+4 (100%); SL = 7 (100%); IL = 8 (83%) or 9 (17%); IL G = 4. Regarding the frequency of IL, it should be noted that the percentages are based on one specimen with IL = 9 on both sides of the head, three specimens with a mix of IL = 8 or 9, and 13 specimens with IL = 8 on both sides of the head. There does not appear to be any sexual dimorphism with respect to V and SC counts in S. heterurus, with values for SCR only minimally different. It is perhaps noteworthy that, unlike in any other species of Stegonotus, the females examined gave a higher maximum subcaudal count than males (93 in females, 88 in males), but this difference is within the standard deviation of the subcaudal count for either sex. The specimens of the original type series from Duke of York have the smallest values for relative tail length, and these are among the lowest for males in the entire genus. This is the only species in the genus other than S. florensis and S. sutteri that possesses entire subcaudal scales. Comments. In order to anchor the name S. heterurus to a single specimen and stabilize the species, we hereby designate BMNH 1946.1.14.95 (Fig. 22 A���E; Table 1) as the lectotype (Code, Article 74.7). It is the largest of the three syntypes, in an excellent state of preservation, and possesses the characteristics we consider diagnostic for the species. This means that the type locality for the species becomes restricted to Duke of York Island, and it renders BMNH 1946.1.14.91 and 1946.1.15.10 as paralectotypes. Given the very wide distribution of S. heterurus across New Britain and New Ireland, an archipelago generally known for its reptile diversity and endemism (e.g., Foufopoulos & Richards 2007; Richards 2011; Clegg & Jocque 2016), the presence of a single species of Stegonotus is perhaps surprising. This is especially noteworthy considering the recently unveiled endemism in the Raja Ampat Archipelago (Ruane et al. 2017) and the diversity we recognize for the Moluccas in this paper. Further research in these islands and the collection of new specimens would allow a molecular analysis to discern the genetic structure in this species and would, perhaps, uncover greater diversity., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 38-40, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Boulenger, G.

Stegonotus aruensis (Doria, 1874:352) n. comb. Taxonomic status. Lycodon aruensis has heretofore been considered as a synonym of S. modestus. Having restricted that species to some of the central Moluccan islands, and combined with the lack of a neck band and a much higher value of SCR in aruensis, we hereby remove this species from the synonymy of S. modestus. This population therefore takes the name Stegonotus aruensis n. comb. Synonyms. None. Original name. Lycodon aruensis Doria, 1874:352. Giacomo Doria (1840–1913; Fig. 17A) was an influential Italian naturalist and founder of a natural history collection in Genoa, Italy. The species is named for the Aru Islands, and the description was presented in Italian. Holotype. MSNG 30186 (Fig. 18; Table 1), most likely an adult male (see below). Type locality. “Wokan (Isole Aru)” [Wokam, Tanahbesar Island, Maluku Province, Indonesia]. There could be some confusion regarding the specifics of the type locality. A literal translation simply yields the place name Wokam and “Aru Islands.” It should be noted that Doria used the plural for island (isole) and not the singular (isola), referencing the reality that “Aru” is actually a complex of several islands, separated by narrow saltwater channels. Specifically, “Wokam” may refer to Tanahbesar, one of the four larger islands that make up the landmass of the Aru Islands, but also to a sparsely populated administrative area on the westernmost extreme of Tanahbesar. The voyage that resulted in the collection of this specimen originated on Ambon and the vessel arrived at the main port of the Aru Islands at Dobo (Doria 1874). The administrative area called Wokam lies just across a saltwater channel from Dobo in the western region of Tanahbesar, and the short distance from Dobo makes it a very likely place for a landfall. Doria (1874) further recounted that the collector Beccari’s travels in the Aru Islands were restricted to the islands’ western coast. This is borne out by a map drawn by Beccari and reproduced in Gigliolo (1873:857), where Locality 1 is labeled as “Wokan.” We therefore restrict the type locality of S. aruensis to the Wokam administrative unit in western Tanahbesar (ca. 5.6636°S, 134.2509°E). Collector. Doria (1874) reported on a collection of specimens made by Odoardo Beccari (1843–1920; Fig. 17B), who traveled extensively in the Malay Archipelago and into Papuasia in the 1860s and 1870s. On this particular trip, Beccari departed Ambon for Dobo in the Aru Islands on 8 February 1872, where he arrived on 22 February 1872 (Anonymous 2018a). On 6 July, Beccari departed Wokam for the Kei Islands (Anonymous 2018a). Thus, the specimen must have been collected between 8 February and 6 July 1872. The photographs of Doria (Fig. 17A) and Beccari (Fig. 17B) are from Doria & Gippoliti (2006) and are used by permission of Giuliano Doria (in litt., 8 August 2018). Key characteristics of the holotype. 560 (582) mm SVL + 240 (233) mm TL = 800 (815) mm TTL. V ♂ = 190 (190), SC ♂ = 100 (103), SCR ♂ = O (0.35), D = O-17-O (17-17-15), SL E = 3+4 (3+4), SL = 7 (7), IL = O (8), IL G = O (4). Based on the high value of SCR, we believe this specimen to be a male and treat it as such. Key characteristics of the species. Other than the holotype, we were able to locate only one additional specimen of S. aruensis (SMF 18055). As a consequence, our assessment of the species-level characteristics is very limited. It appears that S. aruensis, just like S. modestus, is sexually dimorphic with respect to tail length. The putatively male holotype has a high SCR value of 0.35, whereas the second specimen, putatively a female, has an SCR of only 0.29. Beyond that, among the diversity of Stegonotus this species falls into the category of having SL E = 3+4, D = 17-17-15, the lower counts for SL and IL (7 and 8, respectively), as well as IL G = 4. Additional specimens would be needed to ascertain the variability of these characters, or to define the species more broadly.

Stegonotus batjanensis (Günther, 1865) Taxonomic status. Valid. Synonyms. Leptophis batjanensis Bleeker, 1857:473 (nomen nudum) Original name. Coluber (Lielaphis) batjanensis Günther 1865:93. In his fourth list of snakes, Günther placed his new species into a genus he erected to accommodate Coluber holochrous and Spilotes samarensis (see their respective accounts above), two species that have long been in the synonymy of other taxa (with S. modestus and S. muelleri, respectively). Due to the logistical constraints of research at the time, it is doubtful that Günther actually personally examined the type specimens of S. modestus or S. muelleri, the respective taxa in whose synonymy the two putative Lielaphis species were placed. The species epithet references Batjan, an older name for Bacan Island based on Dutch pronunciation, and the description was presented in English. Holotype. BMNH 1946.1.11.36 (Fig. 13; Table 1), formerly BMNH 63.12.4.15, an adult male. The original description included line drawings of the head in dorsal, ventral, and lateral views (Günther 1865: Plate II, Fig. A). Type locality. “Batjan” [Bacan Island, North Maluku Province, Indonesia]. Collector. The specimen is listed as having been collected by Pieter Bleeker, but Bleeker never ventured out into the northern Moluccas (Bleeker 1877; Heiningen 2010). It was most likely sent to London from Batavia as part of Bleeker’s donations, which were assembled from a variety of suppliers. However, since Bleeker departed the Dutch East Indies in the year 1860, the specimen must have been collected before his departure, and likely after his trip through the central Moluccas in 1855, where his interest in the region was kindled (Bleeker 1856). Key characteristics of the holotype. The original description includes measurements of an SVL of 61 in and a tail length of 12 in. This converts to 1549 (1280) mm SVL + 305 (300) mm TL = 1854 (1580) mm TTL. V ♂ = 236 (235), SC ♂ = 78 11 (86), SCR ♂ = 0.27; D = O-17-O (17-17-15), SL E = 3+4+5 (3+4+5), SL = 8 (8), IL = 10, counted from the figure in the original description (10), IL G = O (5). Key characteristics of the species. We were able to examine 28 specimens of S. batjanensis that were collected on one of the four islands to which we are restricting the distribution of the species. Of these, one (the male holotype) was collected on Bacan, 16 (5 ♀♀, 7 ♂♂, four of unknown sex) on Halmahera, four on Morotai (1 ♀, 3 ♂♂), and five on Ternate (2 ♀♀, 2 ♂♂, one of unknown sex). Two additional specimens we examined are clearly members of this species but no locality is available. Characteristics include V ♀ = 203–216 (211 ± 4.5), V ♂ = 221–236 (229 ± 4.3); SC ♀ = 80–90 (84 ± 3.8), SC ♂ = 78–89 (85 ± 3.3); SCR ♀ = 0.28, SCR ♂ = 0.27; D = 17-17-15 (100%); SL E = 3+4+5 (100%); SL = 8 (n = 22, 96%) or rarely 7 (n = 1, 4%); IL = 9 (n = 18, 78%), 10 (n = 4, 17%), or rarely 8 (n = 1, 4%); IL G = 5 (100%). The species displays sexual dimorphism in the non-overlapping ventral 10. Günther (1863a:60) wrote, “If we divide the Colubri with equal or subequal teeth into the subgeneric divisions of Coluber, Elaphis, Cynophis, Spilotes, and Coryphodon, as indicated in my 'Catalogue of Colubrine Snakes,' p. 84, the present species [Coluber holochrous] does not enter any of these sections; and we may propose the name of Lielaphis for a sixth group, of which C. holochrous is the type, and to which also Spilotes samarensis, Peters, belongs.” However, in his Catalogue (Günther 1858:84) these “subgenera” are listed as genera (the term Colubri is not used) and in his third account of new snakes in the British Museum (Günther 1863b:349) he listed Elaphis as a genus. Whereas the subgeneric divisions in the paper on the Ceram herpetofauna are explicit, we believe the taxon levels are better stated to be the tribe Colubri and a division of the tribe into six genera. 11. Given the large difference between our own count and the value listed by Günther (1865), we believe it most likely that Günther inadvertently reversed his numbers and that his actual count would have been 87, including the now missing tail tip scale. count. De Lang (2013) listed dorsal counts of “19, 17, or 15-17-15” for the species, citing several literature sources 12. We found only the 17-17-15 count, although there are specimens that display dorsal count oddities, whereby a few dorsal rows have 16 or 18 rows before returning to the regular count of 17. Comments. Stegonotus batjanensis is a distinctively patterned northern Moluccan regional endemic, whose presence on Bacan, Halmahera, Kasiruta, Morotai, Obi, Ternate, and Tidore is confirmed by voucher specimens (de Lang 2013). We have not seen specimens from Kasiruta, Obi, or Tidore, and we are wondering whether these are the ones with dorsal scale counts that differ from the norm. There are two specimens of S. batjanensis in the collection of the Zoölogisch Museum Amsterdam (ZMA17660 A–B) whose locality is given as Ambon (see also de Lang 2013). This locality is incongruent with the expected northern Moluccan range for the species, placing it at least 300 km to the south of confirmed localities, and on the far side of Seram, from which this species is not known. These two specimens were given to the ZMA during the retrenchment of the Koninklijk Instituut voor de Tropen [Royal Tropical Institute] without a named collector based on the collection’s specimen ledger. We believe that the locality “ Ambon ” is in error, and that Ambon, the main center of economic activity in this area of Indonesia, was merely the shipping point of origin for specimens collected in the region. This is not a unique circumstance, as the example of the Timor python (Malayopython timoriensis) shows, which was not collected and does not occur on Timor, but was merely shipped from Kupang in West Timor (Barker & Barker 1996; O’Shea & Kaiser 2018). 12.

Stegonotus admiraltiensis Ruane et al., 2017:21 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus admiraltiensis Ruane et al., 2017:21. The species name references the Admiralty Islands of Manus Province, Papua New Guinea, where the species is thought to be endemic. The description was presented in English. Type specimens.

Paratypes: LSUMZ 93597, Peyon Village, Los Negros Island, elev. 10 m (ca. 2.0327��S, 147.43��E); LSUMZ 93599���600, northeast of Penchal Village, Rambutyo Island, elev. 100 m (ca. 2.3405��S, 147.79��E). Collection. All type specimens were collected by Christopher C. Austin (Louisiana Museum of Natural History, Baton Rouge, Louisiana, USA) between 29 August and 3 September 2001. Key characteristics of the type specimens. (1) Holotype, LSUMZ 93598: 658 mm SVL + 185 mm TL = 843 mm TTL. V ♂ = 208, SC ♂ = 98, SCR ♂ = 0.32, D = 17-19-15, SL E = 4+5, SL = 8, IL = 10, IL G = 6. (2) Paratype, LSUMZ 93597: 560 mm SVL + 174 mm TL = 734 mm TTL. V ? = 214, SC ? = 94, SCR ? = 0.31, D = O-17-O, SL E = x, SL = 8, IL = 10, IL G = O. (3) Paratype, LSUMZ 93599: 646 mm SVL + 190 mm TL = 836 mm TTL. V ? = 206, SC ? = 93, SCR ? = 0.31, D = O-17-O, SL E = O, SL = 8, IL = 9, IL G = O. (4) Paratype, LSUMZ 93600: 598 mm SVL + 110+ mm TL = 708+ mm TTL. V ? = 202, SC ? = O, SCR ? = O, D = O-19-O, SL E = O, SL = 8, IL = 10, IL G = O. Key characteristics of the species. According to their specimen list, Ruane et al. (2017: Appendix) included four specimens of S. admiraltiensis in their analysis. Of these, one male and two unsexed specimens were collected on Rambutyo, and one unsexed specimen on Los Negros. Given that most of the specimens were not sexed, it is not possible to draw conclusions regarding the distribution of characteristics by sex or about the presence of sexual dimorphism. The characteristics we list here are therefore somewhat limited in their overall description of the species. We consider S. admiraltiensis to be a species with a relatively high ventral scale count (V> 200) with a relatively high number of subcaudal scales (SC> 90; SCR> 0.30). The dorsal count of 17-19-15 is unique among the species of Stegonotus, and its occurrence in a species that also presents dorsal counts of O-17-O (most likely 17-17-15) is unusual. The SL E is most likely 4+5 for the species given that this character tends not to be rarely variable in Stegonotus species. The number of supralabials was eight for all specimens, and among infralabials three specimens had IL = 10, whereas one had SL = 9. Based on the ventral view of the holotype, the sixth infralabial scale barely touches the anterior genial, and we wonder whether this character can be consistently scored as IL G = 6 across all specimens. If so, then this is another unique characteristics of S. admiraltiensis among the species of Stegonotus. Comment. Ruane et al. (2017) compared S. admiraltiensis to S. modestus and S. parvus at length, but without the benefit of having examined the holotype of the former or using the original description of the latter (characteristics of S. admiraltiensis in parentheses): S. modestus has a light neck band (absent), a subcaudal count 90), SL E = 3+4 (4+5), and IL G = 4 (6). Stegonotus parvus has a ventral count 200), SL E = 3+4 (4+5), and IL G = 4 (6). Furthermore, Ruane et al. (2017) referenced two additional Manus specimens but did not include them in their analysis. We have examined an additional 38 specimens from the Admiralty Islands, which include 15-15-15 (n = 3), 17-17-15 (n = 30), and 17-19-17 (n = 5) dorsal counts, with SL E = 3+4 (n = 16) or 4+5 (n = 20), with subcaudal counts that differ from S. admiraltiensis as defined above. Two specimens have aberrant counts of SL E, with 3+4 on one side of the head and 4+5 on the other. It therefore appears to us as if S. admiraltiensis is not the only species of Stegonotus present in the Admiralty Islands and further research will be needed to ascertain the taxonomy of groundsnakes there.

Wilhelm Peters (1815���1883; Fig. 3I) was an influential German zoologist who, for a time, worked as an assistant to Johannes M��ller (for whom S. muelleri was named; see above) in the anatomical institute of the Friedrich-Wilhelms-Universit��t in Berlin. At the time he wrote this species description, Peters had succeeded Martin Hinrich Lichtenstein (1780���1857) as director of the Museum f��r Naturkunde in Berlin. The species was named for the island on which it was collected. The species description was presented in German. The undated portrait of Peters (Fig. 3I; public domain) is from the archives of the ZMB. Holotype. ZMB 4294 (Fig. 11; Table 1), an adult male (according to the original description). The specimen consists of only the skin with the complete head, and it was originally described in this state. Some data (including sex and length measurements) must therefore have been obtained from the specimen by someone other than Peters before it was skinned. Type locality. ���Cubo-Cubo, Insel Samar��� [Coboc��bo, northern Samar Island, The Philippines]. Collection. The specimen was collected by Fedor Jagor (1816���1900; Fig. 3J), a German ethnologist and collector, who for several decades supplied specimens from various parts of Southeast Asia to European museums. Jagor arrived in the town of Laoang on Samar Island by boat on 5 July 1859 and proceeded shortly thereafter (the exact timing is not discernable from Jagor���s own travelogue) into the island���s interior from Catarm��n, a settlement on the northern coast of Samar at the mouth of the Catarm��n River (Jagor 1873, 1875). This journey then continued up the Catarm��n River, along which the settlement of Coboc��bo was reached by rowing continuously for 24 h. Based on the circumstantial evidence provided in Jagor���s account, it is most likely that the specimen was collected during the first half of July 1859. Jagor���s portrait (Fig. 3J; public domain) was drawn in 1886 by the German painter Christian Wilhelm Allers (1857���1915) and published by Olinda (1900).

Herbertophis plumbeus Macleay, 1884:434 Taxonomic status. Junior synonym of S. australis. Type species of the genus Herbertophis Macleay, 1884:434. Synonyms. None. Original name. Herbertophis plumbeus Macleay, 1884:434. The genus name translates as ���Herbert snake,��� in reference to the Herbert River, Queensland, Australia. The species name comes from the Latin, with plumbeus meaning lead-like, presumably to denote the snake���s ���nitid 17 leaden-black colour above��� (Macleay 1884:434). The species description was presented in English. Holotype. AMS R31895 (Fig. 21; Table 1), an adult male. Type locality. ���Ripple Creek, Herbert River��� [Ripple Creek Plantation along the Herbert River, near Ingham, Queensland, Australia, ca. 18.58��S, 146.21��E]. Ripple Creek is a small tributary to the Herbert River, but it is unlikely that collection activity was specific to the creek only. Instead, the specimen could have been collected anywhere on the lands of the Ripple Creek Plantation (Connor 2017). The sugar cane plantation, now defunct, extended from the northern bank of the Herbert River, in the area where Ripple Creek enters the river, to the Seymour River (ca. 3 km to the north). Collection. At the beginning of his account, Macleay (1884) recounted that a few days before the writing of this paper commenced, ���Mr. Archibald Boyd of Ripple Creek, Herbert River��� brought him ���an earthenware jar��� with a series of unidentified vertebrates. We believe that the jar���s contents came from the collecting activities of the then-plantation overseer, John Archibald Boyd (1846���1926; Fig. 17D), who had become an expert collector of natural history specimens during nearly two decades spent in Fiji (Henry 2014; Greer et al. 2016). The photograph of Boyd (Fig. 17D; public domain) was taken in 1888 by the Australian photographer Algernon Hall (1828���1905), who made his name photographing towns and portraits in Victoria and Queensland.

The dorsal count of 17 was provided in the generic description, as a diagnostic feature of Herbertophis. Key characteristics of the species. See the account of S. australis above. Comment. Macleay (1884) placed his new genus Herbertophis into ���Gray���s family or group, Coronellidae��� (now part of Colubridae). 17. The term ���nitid��� comes from the Latin and means shiny or glistening. We assume that this term is used here to indicate that the snake���s color is not a matte black but a shiny black. It could also be used to imply the presence of iridescent sheen., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 37, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Macleay, W.

Lycodon darnleyensis Macleay, 1877:38 Taxonomic status. Junior synonym of S. australis. Synonyms. None. Original name. Lycodon Darnleyensis Macleay, 1877:38. William Macleay (1820���1891; Fig. 17C) was an Australian naturalist and politician, who personally financed the voyage of the sailing ship Chevert to New Guinea, the first Australian foreign exploration. He named this species for one of the islands in the Torres Strait Archipelago. The species description was presented in English. The undated photograph of Macleay (Fig. 17C; public domain) is from the archives of the AMS. Holotype. AMS R31894 (Fig. 20; Table 1), an adult female. Type locality. ���Islands of Torres Straits and Hall Sound, New Guinea ��� [Darnley Island, Torres Strait, Queensland, Australia, ca. 9.5870��S, 143.7710��E, by implication]. Even though Macleay (1877) did not specify a type locality, it is unequivocally provided by the species name. Darnley (or Erub, in the indigenous language) is a small (5.5 km 2) volcanogenic island, lying only ca. 80 km off the coast of Western Province, Papua New Guinea. Collector. The Chevert anchored at Darnley Island (called Darnly Island in the ship���s log) from 31 July���12 August 1875 (Davidson 2017). There were daily trips to the island by members of the research party, so it is not possible to pinpoint the collection date with greater accuracy.

See the account of S. australis above. Comments. The set of infralabial scales on the right side of the holotype presents one unusual feature, a fragmentation of IL9 into two small, shallow scales, each of which we counted to arrive at our count of IL = 10 L. Boulenger (1893) synonymized the species with S. cucullatus, he indicated some doubt regarding his decision by including a question mark before the species name., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 36-37, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Macleay, W.

Stegonotus guentheri Boulenger, 1895:31 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus Guentheri Boulenger, 1895:31. Boulenger (1895) named this species for Albert G��nther (see the account of Coluber holochrous above), his predecessor at the British Museum of Natural History. The species description was presented in English. Syntypes. BMNH 1946.1.11.37���38 (formerly 95.4.26.47���48), an adult male and an adult female, respectively, and 1946.1.11.39 (formerly BMNH 95.4.26.49), an adult female (Fig. 23). Type locality. ���Fergusson Island, D���Entrecasteaux Group, British New Guinea ��� [Milne Bay Province, Papua New Guinea; ca. 9.54��S, 150.67��E]. Collection. The collection from which Boulenger obtained these specimens was made by the English naturalist Albert Stewart Meek (1871���1943; Fig. 17G), who visited the D���Entrecasteaux Archipelago in 1894���95. In reports on Meek���s exploits in the region (Hartert 1895; Rothschild & Hartert 1896; Meek 1913; O���Shea & Kaiser 2018), the earliest date listed for discoveries on Fergusson is September 1894, the latest June 1895. Meek decamped from Fergusson after a 4-month stay (likely in January 1895) and traveled to Samarai Island, the British administrative center at the time, in order to reprovision and dispatch his specimens to London (Meek 1913). Given that the description of S. guentheri appeared in the July 1895 issue of the Annals and Magazine of Natural History, this leaves enough time for the collection to reach the BMNH. Later collections on Fergusson during 1895 would not have had sufficient transit time for shipping to the United Kingdom. The specimens therefore must have been collected during Meek���s initial 4-month stay on Fergusson, during the months of September���December 1894. The undated photograph of Meek (Fig. 17G; public domain) was also published by D���Abrera (2003). Key characteristics of the type specimens. (1) BMNH 1946.1.11.37: 920 (929) mm SVL + 230 (234) mm TL = 1150 (1163) mm TTL.

V ♀ = O (185), SC ♀ = 75 (78), SCR ♀ = O (0.30), D = O-15-O (15-15-13), SL E = O (4+5), SL = O (8), IL = O (9), IL G = O (5). Key characteristics of the species. We have been able to examine 38 specimens of S. guentheri. Of these, 37 were collected in the D���Entrecasteaux Archipelago, eight (3 ♀♀, 5 ♂♂) on Fergusson Island, 16 on Normanby Island (3 ♀♀, 13 ♂♂), and 13 (3 ♀♀, 10 ♂♂) without further locality data. One male was collected on Kuia [Kuyau] Island in the Trobriand Islands, ca. 90 km north of Fergusson. Characteristics include V ♀ = 174���198 (187 �� 6.4), V ♂ = 185���198 (191 �� 3.5); SC ♀ = 64���80 (74 �� 4.9), SC ♂ = 64���80 (73 �� 4.3); SCR ♀ = 0.28, SCR ♂ = 0.28; D = 15-15-13 (100%); SL E = 4+5 (n = 37, 97%) or, rarely, 3+4 (n = 1, 3%); SL = 8 (n = 38, 97%) or 7 (n = 1, 3%); IL = 9 (100%); IL G = 5. A key difference between S. guentheri and all other species of Stegonotus is the number of dorsal scale rows, which diminishes from 15 to 13 along the body. There is no other species of Stegonotus with 15- 15-13 dorsal rows; S. diehli and S. dorsalis (see below) have 15-15-15 rows. There does not appear to be any sexual dimorphism when considering the numbers of ventrals or subcaudals. Comments. In the interest of nomenclatural stability, we hereby designate BMNH 1946.1.11.38 (Fig. 23 A���E; Table 1) as the lectotype of S. guentheri (Code, Article 74.7). This specimen is a female syntype with a complete tail. This renders BMNH 1946.1.11.37 and 1946.1.11.39 as paralectotypes. In the D���Entrecasteaux Archipelago, the distribution of S. guentheri appears to be limited to Fergusson and Normanby Islands, the two largest islands. The species has not been recorded from Goodenough Island, the third larger island in the group. One specimen (AMS 86835) that fits the characteristics of S. guentheri was collected farther afield, on Kuia Island (variant spellings include Kuyau and Kuiao; Austen 1939; Fitzer & Geelan 1956; Hensley & Allen 1977), a small island in the Trobriand Islands to the north., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 41, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Boulenger, G.

Stegonotus parvus (Meyer, 1874:137) Taxonomic status. Valid. Syntypes destroyed, no type material available. Synonyms. None. Original name. Lycodon parvus Meyer, 1874:137. The species name parvus is a Latin word meaning “small” and, other than to describe the small size of the specimens collected, it is not obvious why Meyer would have selected this name 13. The species description was presented in German. Syntypes. MTKD 876 (Table 1). According to Schüz (1929), two specimens had been accessioned under this single number. These were destroyed in the Second World War, during the Allied air raids on Dresden on 13–15 February 1945, along with most other herpetological specimens at the MTKD. Type locality. “Neu-Guinea, Jobi” [Yapen Island 14, Papua Province, Indonesia]. Collection. Meyer (1887) specified that the collection on Yapen was made at Ansus, a settlement on the south shore of the island (ca. 1.7341°S, 135.8263°E), and Meyer (1875) gave 8 April 1873 as his arrival date there. In his hypercritical review of Meyer’s reports, Wichmann (1910 15) gave 8–29 April 1873 as the specific dates for the visit to Ansus, and these dates correspond to those provided by Meyer himself. Meyer (1875) also stated that the collection activities spanned 19 days. Based on his account, it appears the arrival occurred late in the day and the following day was spent with negotiations; the departure occurred at dawn on 29 April. Therefore, specimen collection on Yapen must have occurred on 10–28 April, during which time Meyer collected 30 species of amphibians and reptiles (Meyer 1875). Key characteristics of the syntypes. Given that the syntypes were destroyed, we are not able to determine which one of the two specimens served as the origin for the scale counts. The only mention in the original description that two specimens were, in fact, utilized is in the fourth sentence, where Meyer commented that “in einem Exemplar von den zweien vorhandenen” [in one specimen of the two that are available] there was a fusion of the prefrontals. The following values were clearly based on data from only one of the syntypes: O (O) mm SVL + O (O) mm TL = O (O) mm TTL. V = 177 (O), SC = 100 (O), SCR = 0.36 (O), D = O-17-O (O), SL E = 3+4 (O), SL = 7 (O), IL = O (O), IL G = O (O). There were no data provided for the second specimen. In contrast to our other accounts, we have not denoted whether the ventral scale counts in this list belong to a male or female specimen. Based on the high SCR value, we believe that the examined individual was most likely a male. Key characteristics of the species. Given that only two specimens of this species are known with certainty (the syntypes), and with both of these having been destroyed, the basis for any species-level diagnosis is all too 13. It is perhaps relevant that Meyer named his two new species parvus (small) and magnus (large). This could indicate that Meyer considered magnus large compared to parvus from Yapen, even though we can now state that magnus is not necessarily large compared to other mainland Stegonotus. 14. The locality of Yapen Island has also been spelled “Japen.” The latter is, however, an Anglicized version of a Papuan name, used predominantly by the Allied Forces during the Second World War and having entered the mainstream of location names as a consequence. We prefer to use the original spelling. 15. During his last years as director of the Dresden museum, Meyer was the target of anti-Semitic intrigue (Fritz 2002), which appears to have brought his long and highly successful term as a scientist to an undeservedly premature end. To the heading of his account, Wichmann (1910) included a footnote to disclose that Meyer’s real name was Aron Baruch Meyer, a name indicating a Jewish heritage. The entire text thereafter is composed of accusations against Meyer, asserting his incompetence and untruthfulness, but generally amounting to hearsay presented as analysis. Wichmann ended his account with a nasty flourish, declaring: “In der Wissenschaft wird aber der Name dieses Mannes, dem die Wahrhaftigkeit niemals etwas anderes als eine abgegriffene Ware gewesen ist, als ein abschreckendes Beispiel noch über Jahrhunderte hinaus fortleben.” [The name of this man, to whom truthfulness was never anything but a worn-out commodity, will live on in science for centuries to come as an off-putting example.] limited. We can state that, compared to all other species of Stegonotus, S. parvus has a low ventral count (Comments. Meyer (1887) listed Lycodon parvus as a member of the family Lycodontidae and in the synonymy of L. lividus. Designation of a neotype. The lack of a type specimen for Stegonotus parvus is a significant hindrance to unraveling the taxonomy of the populations of Stegonotus in New Guinea and parts of Australia, where this name has been applied to dozens of specimens. Article 75 of the International Code of Zoological Nomenclature (ICZN 1999) permits the designation of a neotype when specific qualifying conditions are met, and in this section we present the relevant declarations. To satisfy the conditions of Article 75.3.1, we attest that with the available information, it is not possible to ascertain the taxonomic status of S. parvus. As a consequence, the application of this name since the destruction of the syntypes has been prone to error and has introduced a significant amount of uncertainty over the identity of groundsnakes throughout New Guinea and parts of Australia. Designation of a neotype is imperative to stabilize the taxonomic status of the species and the taxonomy of the genus as a whole. To satisfy the conditions of Article 75.3.2, we refer the reader to the description in Meyer (1874). In addition to the key characteristics we list above, the original description provided the following head scale characteristics: rostral barely reaching the upper surface of the head; internasals trapezoid in shape, narrower anteriorly; prefrontals very wide, irregularly hexagonal; frontal nearly triangular, but pentagonal upon closer examination; loreal longer than wide; two pre- and two postoculars; 2+2+2 temporals; body scales lack pits; single cloacal plate. To satisfy the conditions of Article 75.3.4, we hereby declare that we have unsuccessfully attempted to locate the syntypes of S. parvus by requesting information regarding their status from the curatorial staff at the Museum für Tierkunde, Dresden, Germany. Whereas the pre-war list of type material by Schüz (1929) included the two syntypes (MTKD 876), neither of the post-war type lists compiled by Obst (1977) and Fritz (2002) referenced them. It is understood that the syntypes were destroyed in the Allied bombing raids on Dresden in 1945. The proposed neotype (RMNH.RENA 46844; Fig. 16, Table 1) is a female that was collected by D.L. Leiker 16 on 22 February 1952 at Serui, Yapen Island, Papua Province, Indonesia (ca. 1.8807°S, 136.2386°E). This location is about 50 km distant (by air) from the original type locality and in the same type of lowland habitat on the southern coast of Yapen, thus satisfying Article 75.3.6. The neotype has the following characteristics (where these differ in wording or qualitatively from those of the syntype used in the description, the values for the syntype are listed in parentheses): rostral barely reaching the upper surface of the head; internasals trapezoid in shape, narrower anteriorly; prefrontals very wide, irregularly hexagonal; frontal nearly triangular, but pentagonal upon closer examination; loreal 1.3 times longer than wide (longer than wide); one preocular (two preoculars); two postoculars, but on both sides of the head the lower postocular is fused with the 4 th supralabial (two postoculars); seven supralabials, the 3 rd and 4 th touching the eye; eight infralabials (no value given); 2+3+2 (2+2+2) temporals; 17-17-15 (only a middorsal count of 17 was given) dorsal scale rows, body scales lacking pits; single cloacal plate; V ♀ = 173 (V ♂ = 177), SC ♀ = 87 (SC ♂ = 100). We believe that the difference in the subcaudal count is a reflection of the sex of the specimen. Whereas the neotype is a female with an SCR ♀ of 0.33, the syntype for which scale counts were listed in the original description is most likely a male at an SCR ♂ of 0.36. Males of several Stegonotus species (S. florensis, S. keyensis, S. modestus, S. sutteri) have longer tails relative to body length than females, and this can explain the discrepancy seen in the SC values between the neotype and the syntype whose characters are known. Additional characteristics for the neotype include 217 mm SVL + 75 mm TL = 292 mm TTL, IL 1–4 touching the anterior genial, the body pigmentation not extending onto the ventral scales, and darkly pigmented subcaudal scales. These values satisfy the conditions of Article 75.3.5. We believe that the last two paragraphs along with the images shown in Fig. 16 satisfy the conditions of Article 75.3.3. The neotype was accessioned into the Naturalis Biodiversity Center in Leiden, The Netherlands (RMNH), on 17 February 1953. The RMNH maintains a public research collection with proper facilities for preserving namebearing types, and these are accessible for study. This statement satisfies Article 75.3.7. 16. Dick L.

Stegonotus modestus (Schlegel, 1837:119) Taxonomic status. Valid. Synonyms. Lycodon lividum Duméril et al., 1854; Ablabes greineri Bleeker, 1860a; Coronella rosenbergii Bleeker, 1860b; Coluber holochrous Boulenger, 1863; Lycodon aruensis Doria, 1874. Original name. Lycodon modestus Schlegel, 1837:119. In the second volume of his expansive treatise on snakes, Hermann Schlegel (1804–1884; Fig. 3A), then employed as assistant to the director of the Rijksmuseum van Natuurlijke Historie in Leiden, The Netherlands (RMNH), described this taxon as a member of the genus Lycodon. The Latin species epithet means “moderate” in English and was perhaps used to indicate that this was a fairly nondescript form compared to some of the other members of the genus Lycodon, as then recognized. The species description was presented in Dutch. The image of Schlegel (Fig. 3A; public domain) is from a lithograph by the Belgian illustrator Abraham Jacobus Wendel (1826–1915). 5. There is no uniform terminology for the scales covering the chin region of a snake’s head. An informal literature survey revealed that the terms “genials” and “chin shields” have been used widely throughout the historical and recent literature. Ruane et al. (2017) recently used the term “inframaxillary” for these scales, a term we find most commonly used by 19 th Century authors. We prefer the term “genials” for two reasons. (1) Any scale in the chin region of a snake’s head is strictly a chin shield (or chin scale, or chin plate), and this term may therefore be ambiguous—especially should a translation to another language be necessary. (2) The term “inframaxillary” relates the position of a visible external feature (the scale) to an invisible internal one (the bone). We believe this is not optimal, especially considering that the skull of many snakes is very kinetic and the position of the maxillary bone can shift. Holotype. RMNH. RENA 324 (Fig. 4; Table 1), an adult male. Type locality. “Amboine” [Ambon Island, Maluku Province, Indonesia]. Collection. The specimen was collected by Salomon Müller (1804–1864), a key member of the Dutch expeditions to the East Indies under the umbrella of the Natuurkundige Commissie voor Nederlandsch-Indië [Natural History Commission for the Dutch Indies]. He appears to have been a productive collector in the Indonesian archipelago in the time from 1826–37 (Steenis-Kruseman 1950), and he distinguished himself among the Dutch explorers of the time by surviving his travels and returning to his homeland. Müller settled down as a scientist to work on his collection until the Commission was disbanded in 1850 and he retired. It is curious, given Müller’s contributions to natural history, that no photograph or other illustrations of him appear to exist (Charles Klaver, in litt.). The time frame of the specimen’s collection is given by the schedule of the corvette Triton and the schooner Iris, which arrived on Ambon on 5 September and departed on 7 October 1828 (Macklot 1829), to drop off the members of the Commissie, including Müller, at Kupang on Timor on 14 October 1828 (Macklot 1829; Steenis-Kruseman 1950). Thus, the specimen must have been collected between 5 September and 7 October 1828 (Müller 1857). Key characteristics of the holotype. 700 (656) mm SVL + 210 (206) mm TL = 910 (862) mm TTL. V ♂ = 200 (198), SC ♂ = 84 (83), SCR ♂ = 0.30 (0.30), D = O-17-O (17-17-15), SL E = O (3+4), SL = O (7), IL = O (8), IL G = O (4). Based on its SCR of 0.30 the holotype falls well outside the SCR values for females (see below) and can there-fore be identified as a male. Key characteristics of the species. We were able to examine 18 specimens of S. modestus that were collected on the three major islands to which we are restricting the distribution of the species (see below). Of these, eight (4 ♀♀, 4 ♂♂) were collected on Ambon, six on Buru (6 ♂♂), and four on Seram (4 ♂♂). These include the holotypes of Ablabes greineri, Coluber holochrous, and Coronella rosenbergii (see individual accounts for each of these species below). Characteristics include V ♀ = 190–198 (194 ± 3.5), V ♂ = 195–206 (202 ± 3.3); SC ♀ = 58–68 (63 ± 4.4), SC ♂ = 78–94 (84 ± 4.5); SCR ♀ = 0.24, SCR ♂ = 0.29; D = 17-17-15 (100%); SL E = 3+4 (n = 16, 89%) or rarely 4+5 (n = 2, 11%); SL = 7 (n = 11, 61%) or 8 (n = 7, 39%); IL = 8 (n = 10, 59%), 9 (n = 6, 35%), or 10 (n = 1, 6%); IL G = 4 (100%). In this species, there exists some sexual dimorphism with respect to V and SC counts, with females having values of V S. modestus have slightly longer tails than females. Comments. An important characteristic for the identification of this species is the incomplete light-colored band that marks the posterior extent of the head. This neck band is bisected by one or two brown scales mediodorsally, and it is two or three light scales wide along the lateral side of the body. The band is sometimes faint but present in a majority of specimens (89%) and living individuals. This Maluku Island regional endemic appears to be the only species of Stegonotus featuring this characteristic type of band in adults. We consider the species confirmed only for Ambon, Buru, and Seram, but we see no reason why it would not also occur on some of the associated smaller islands in the northern part of Maluku Province, Indonesia (e.g., Boano, Haruku, Kelang, Maripa, Saparua). De Lang (2013) cited a personal communication regarding the presence of this species on the Tanimbar Islands, Maluku Province, Indonesia, but we have not found any record of actual specimens from there. Given our concept of S. modestus as a central Moluccan regional endemic, a population of Stegonotus in the nearly 400 km distant Tanimbar Islands could, with high probability, be a separate species. As a consequence of restricting the terra typica of this species to the islands listed above, Lycodon lividum from Semau Island (ca. 800 km to the southwest) and Lycodon aruensis from the Aru Islands (ca. 500 km to the southeast) need to be removed from the synonymy of S. modestus (see their individual accounts below for a review of their taxonomic status). An additional, unfortunate consequence of a more restricted type locality for S. modestus is that most of the specimen identifications and assumptions regarding the identity and distribution of this species, such as those made by McDowell (1972) and Ruane et al. (2017), are now shown to be incorrect. In fact, McDowell (1972) already pointed out that even within the purported members of S. modestus in Papua New Guinea alone three distinct forms existed, leading him to present the species name as “ S. modestus ” (in quotation marks) and lamenting the unreliability of commonly used morphological data. The molecular data of Ruane et al. (2017: Fig. 3) also clearly indicated a taxonomic division in these forms, and their data identified a distinct population of Stegonotus in north-central New Guinea. However, these authors erred in applying the name S. modestus to that population., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 9-12, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Schlegel, H.

Stegonotus borneensis Inger, 1967:82 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus borneensis Inger, 1967:82. The species description was presented in English. Type specimens. FMNH 164746 (holotype; Table 1) and USNM 130244 (paratype), both adult females (Fig. 30). Type localities. The holotype is from ���Nanga Tekalit, Kapit District, Third Division, Sarawak ��� [Malaysia] with GPS coordinates given as 1��38���N, 113��35���E [ca. 1.63��N, 113.58��E, elevation ca. 56 m]. The paratype was collected at ���Bundu Tuhan, Mount Kina Balu, Ranau District, Sabah ��� [Malaysia], with GPS coordinates given as ��� 6��03'N, 116��32'E ��� [ca. 6.05��N, 116��53���E] and a listed elevation of 1370 m. The two type localities are separated by a distance of ca. 650 km by air and by an elevation of over 1300 m. Collection. The holotype was collected on 24 May 1963 by F. Wayne King (born 1936), Curator Emeritus at the Florida Museum of Natural History in Gainesville, Florida, USA. The paratype was collected on 1 August 1951 by David H. Johnson (1912���1996), curator of mammals at the National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA, from 1941���1965. Key characteristics of the type specimens. Holotype: 783 (715) mm SVL + 221 19 (221) mm TL = 1004 (936) mm TTL. V ♀ = 194 (193), SC ♀ = 79 (78), SCR ♀ = 0.29 (0.29), D = 21 20 -17-15 (17-17-15), SL E = 4+5 (4+5), SL = 9 (9), IL = 10 (10), IL G = 5 (5). Paratype: 910 (965) mm SVL + 221 (191) mm TL = 1004 (1156) mm TTL. V ♀ = 218 (218), SC ♀ = 79 (62), SCR ♀ = 0.29 (0.22), D = 21-17-15 (17-17-15), SL E = 4+5 (4+5), SL = 9 (9), IL = 10 (10), IL G = 5 (5). Key characteristics of the species. We have been able to examine five specimens of S. borneensis. Of these, two (1 ♀, 1 ♂) were collected in lowland localities in Sarawak, whereas the other three (3 ♀♀) were collected at montane elevations (> 800 m) in Sabah. It is of considerable taxonomic interest that the two specimens that were used to define a single species possess quite disparate characteristics. The values of ventral and subcaudal scales (V ♀ = 193, V ♂ = 196 and SC ♀ = 78, SC ♂ = 78 in Sarawak, V ♀ = 211���218 and SC ♀ = 56���65 in Sabah), including the concomitant values of SCR (0.29 for the female and 0.28 for the male in Sarawak, a range of 0.21���0.24 for the females in Sabah) are non-overlapping and quite distinctive, given the distribution and variation of these characters in other species of Stegonotus. Furthermore, in his original description Inger (1967) already presented another feature to distinguish between the Sabah and Sarawak forms. He noted that the vertebral scale row was ���enlarged and truncate��� in the Sarawak specimen and ���less conspicuously enlarged��� in the Sabah specimen. We conclude that the evidence shows that the high-elevation form from Sabah should be considered distinct at the species level. Our description of this form will appear in a separate publication (C. Kaiser & H. Kaiser, in press). The population from Sarawak will retain the name S. borneensis, and based on values of SCR, there does not appear to be any sexual dimorphism in relative body length. Given the limited data from the two available specimens (FMNH 164746, 188500), we expect this species to be characterized by a relatively high ventral count (195 �� 5 in both sexes), medium range subcaudal count (80 �� 5 in both sexes), and SCR in the high 20% range. We expect other features, including the numbers of supralabials (9), infralabials (10), SL E (4+5), and IL G (5) to be constant in the species. Comments. The skull of the holotype was removed for detailed examination, which can perhaps account for some of the differences between the original and our measurements of SVL. For a better characterization of the species from both Sarawak and Sabah, it is essential that additional material should be collected. Furthermore, it would be interesting to determine whether the species also occurs in the lowland forests of Kalimantan, the Indonesian part of Borneo., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 52-54, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Inger, R.

Stegonotus muelleri Dum��ril et al., 1854:682 Taxonomic status. Valid. Synonyms. Spilotes samarensis Peters, 1861. Original name. Stegonotus M��lleri Dum��ril et al. 1854:682. The authors listed in their synonymy for the species the name Herpetodryas M��lleri with reference to the ���Mus��e de Leyde,��� which indicates that there must have been a specimen label with this name in that museum. The species was named for the German physiologist Johannes M��ller (1801���1858), whose Handbuch der Physiologie [Handbook of Physiology] was the physiology textbook of choice for decades and made him one of the most influential physiologists of the 19 th Century. The species description was presented in French. Holotype. MNHN 848 (Fig. 7; Table 1), an adult female. Type locality. ���Java��� [Java Island, Indonesia]. This locality is in error (see below). The specimen was certainly collected in the southern Philippines, where the species is known only from the islands of Dinagat, Leyte, Mindanao, and Samar (University of Kansas collection data, accessed online via VertNet). Collection. The provenance of this specimen is problematic. In the original description, Dum��ril et al. (1854) stated that the origin of the specimen was Java (without further elaboration), and recounted that it had arrived in Paris from the RMNH in 1845. At the RMNH, the specimen had arrived some time earlier as a donation from Johannes M��ller in Berlin, along with a specimen of a species Dum��ril et al. (1854) described as Lycodon M��lleri from Java, a species known to exist only in the northern Philippines (see Leviton 1965). As professor for anatomy and physiology, M��ller was a member of the anatomy department at the University of Berlin and received material for study from students, former students, commercial dealers, and via institutional exchanges. Examination of the collection data available at the museums in Paris, Leiden, and Berlin regarding the acquisition specifics of this specimen has, unfortunately, proven unsuccessful. It is therefore not possible to trace its provenance beyond Berlin. It should be noted, however, that with the strong Dutch presence on Java much, if not most, of the shipments from the far reaches of Southeast Asia would at the time have come through the port at Batavia (now Jakarta) on Java. It is therefore likely that the proximal shipping port (Batavia) was given as a shipment���s origin instead of a true collecting locality, leading to the locality error. Compounding the issue of erroneous type localities for species named muelleri is the division of specimens into jars at the Paris museum. There are currently two tall glass jars (Fig. 8A,B) holding four specimens. The taller jar (numbered C684) contains two specimens (MNHN 848, 1320), and the shorter one (numbered C684/1) also contains two specimens (MNHN 5764, 5764A). Jar C684 has an affixed label identifying it as containing Stegonotus mulleri [sic] and including the citation of Dum��ril et al. (1854) and collection information given as ���Java: J. Muller��� (Fig. 8C). It is in this jar where both the holotypes of S. muelleri (MNHN 848) and L. muelleri (MNHN 1320) are currently housed. Jar C684/1 has an external label identifying the specimens as Lycodon m��lleri [sic] and giving the collecting locality as ���Lu��on. Montano Rey��� (Fig. 8E) and an internal label identifying the specimens as Stegonotus mulleri [sic] from ���Ile Lu��on,��� providing two additional numbers, 1880-217 and 1880- 218 (Fig. 8D). It is clear from the text of the original descriptions of the two muelleri species that each was written using a single reference specimen. Based on specimen length and body coloration, it is also clear that MNHN 848 is the holotype of Stegonotus muelleri. Using the same characteristics, it is possible to identify MNHN 1320 as the holotype of Lycodon muelleri. The two specimens in Jar C684/1 are clearly not representatives of S. muelleri, as the internal label would suggest, but merely two additional specimens of L. muelleri without type status, probably added to the collection in 1880. Key characteristics of the holotype. 1002 (1006) mm SVL + 30 (302) mm TL = 1032 (1308) mm TTL. In the original description, the length values were given as ��� 1 m 002���, ���0 m,030���, and ��� 1 m,032���, respectively [1002 mm, 30 mm, and 1032 mm, respectively]. It is apparent that the second value in this list is a typo and should read 0 m 300, which would result in a TTL of 1302 mm. V ♀ = 220 (217), SC ♀ = 100 (97), SCR ♀ = 0.31 (0.31), D = O-17-O (19- 17-15), SL E = 4+5 (4+5), SL = 8 (8), IL = O (9), IL G = O (4). Key characteristics of the species. We have been able to examine 32 specimens of S. muelleri. Of these, one (♂) was collected on Dinagat, three on Leyte (2 ♀♀, 1 ♂♂), 12 on Mindanao (7 ♀♀, 4 ♂♂, one unsexed), and 16 on Samar (3 ♀♀, 12 ♂♂, one unsexed). The latter include the holotype of Spilotes samarensis (see below). Two additional conspecifics have no specific locality data. Characteristics include V ♀ = 217���234 (227 �� 4.7), V ♂ = 226��� 241 (235 �� 3.1); SC ♀ = 86���103 (97 �� 5.3), SC ♂ = 85���108 (97 �� 7.0); SCR ♀ = 0.29, SCR ♂ = 0.30; D = 19-17-15 (100%); SL E = 4+5 (100%); SL = 8 (100%); IL = 10 (100%); IL G = 4 (100%). Unlike in S. modestus, there does not appear to be any sexual dimorphism with respect to V and SC counts. Values of SCR are within 0.01 of each other, and the female holotype has an SCR value equal to the average male SCR. As a rule, V> 220 and SC> 80, with SL 4+5 touching the eye, an SL count of 8 and an IL count of 10 appear to be diagnostic of this species. This species appears to be the only one in the genus, in which the slightly greater dorsal count right behind the head extends for more than one head length beyond the head. The usual 17-17-15 dorsal count commences in the region between one and two head lengths behind the head. Comments. In his listing of S. muelleri, Boulenger (1893) reported a total length for the type specimen of 2070 mm, with a tail length of 390 mm. We believe that in the measurement for total length two typos occurred (perhaps due to errors in the transcription of handwriting), such that the number 1070 for total length was replaced by 2070, and the number 300 for tail length by 390. We do not believe that Boulenger���s source, Fran��ois Mocquard (1834��� 1917), at the time of Boulenger���s writing curator of the Paris museum, would have made such egregious measurement errors., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 16-19, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Dumeril, A. - M. - C., Bibron, G. & Dumeril, A. - H. - A.

Stegonotus reticulatus (Boulenger, 1895:31) Taxonomic status. Stegonotus reticulatus has heretofore been considered as a synonym of S. cucullatus. We use the following characteristics to differentiate this species from S. cucullatus (whose characteristics we provide in parentheses): (1) IL G = 4 (5); (2) the length of the internasal suture is ḵ 50% of internasal width (the rostral invades the internasal area and nearly separates the internasals); (3) the suture separating the prefrontals and the frontal lies posterior to or is level with the anterior edge of the eyes (anterior to eyes); (4) the chin area is separated from true ventral scales (gastrosteges) by only one scale in the ventral midline (two scales); and (5) the absence of any specimens with the characteristic reticulated scale pattern from the Bird’s Head Peninsula, the type locality of S. cucullatus. Based on these differences, and based on the uncertainty surrounding the species cucullatus (see above), we hereby remove this strikingly-patterned species from the synonymy of S. cucullatus. Synonyms. None. Original name. Stegonotus reticulatus Boulenger, 1895:31. In naming this form, Boulenger (1895) used the term reticulatus (Latin = net-like) descriptively, in reference to the striking dorsal patterning found in these animals. The pattern itself comprises darkened edges around all dorsal scales, producing a netlike surface coloration. The species description was presented in English. Syntypes. BMNH 1946.1.14.87–88 (Fig. 24), formerly BMNH 95.4.26.50–51, an adult female and an adult male, respectively. Type locality. “Fergusson Island, D’Entrecasteaux Group, British New Guinea ” [Milne Bay Province, Papua New Guinea; ca. 9.54°S, 150.67°E]. Collection. These specimens were also collected by A.S. Meek (see the account of S. guentheri above). Key characteristics of the type specimens. (1) BMNH 1946.1.14.87: 890 (880) mm SVL + 250 (238) mm TL = 1140 (1118) mm TTL. V ♀ = 201 (201), SC ♀ = 78 (78), SCR ♀ = 0.28 (0.28), D = O-17-O (17-17-15), SL E = 4+5 (4+5), SL = 8 (8), IL = O (9), IL G = 4 or 5 (4). (2) BMNH 1946.1.14.88: 1080 (1124) mm SVL + O (broken tail) mm TL = O (O) mm TTL. V ♂ = 203 (204), SC ♂ = O (O), SCR ♂ = O (O), D = O-17-O (17-17-15), SL E = 4+5 (4+5), SL = 8 (8), IL = O (9), IL G = 4 or 5 (4). Key characteristics of the species. We have been able to examine 144 specimens (34 ♀♀, 82 ♂♂, 28 unsexed) of S. reticulatus from all mainland provinces of Papua New Guinea with the exception of Enga and Morobe Provinces. We have so far located a single specimen from Indonesian New Guinea, from Padaido Island, a small island off the eastern coast of Biak Island, Schouten Islands, Papua Province, Indonesia (USNM 119549). Characteristics of S. reticulatus include V ♀ = 186–215 (202 ± 8.2), V ♂ = 188–230 (208 ± 7.7); SC ♀ = 73–88 (82 ± 4.3), SC ♂ = 71–92 (83 ± 5.2); SCR ♀ = 0.29, SCR ♂ = 0.29; D = 17-17-15 (100%); SL E = 4+5 (n = 140, 97%) or 3+4 (n = 4, 4%); SL = 7 (n = 3, 2%), 8 (n = 81, 56%), or 9 (n = 42%); IL = 9 (n = 61, 42%) or 10 (n = 83, 58%); IL G = 4 (100%). Whereas males tend to have more ventrals and more subcaudals than females on average, these differences are not statistically significant and there does not appear to be any sexual dimorphism in these counts. We note that, compared with other well-defined species of Stegonotus, the ranges of ventrals and subcaudals in S. reticulatus are rather large (ranges of 29 and 42 ventrals, and 15 and 21 subcaudals in females and males, respectively), and the relatively large standard deviation values may indicate that there could be cryptic taxa hidden in this widely distributed morphotype. Comment. In order to stabilize the nomenclature of S. reticulatus, we hereby designate BMNH 1946.1.14.87 (Fig. 24 A–E; Table 1), the female specimen, as the lectotype of this species (Code, Article 74.7). This specimen is the only syntype with a complete tail, and given the importance of the number of subcaudal scales in diagnoses of species in the genus Stegonotus, it is relevant to ascertain that this characteristic can be fully evaluated. This designation renders BMNH 1946.1.14.88, the male syntype with a broken tail, as a paralectotype. Even though specimen data for S. reticulatus are sufficient to separate the reticulated morphotype from S. cucullatus, it remains unclear whether the specimens we examined represent more than one species. It does appear as if the species is found primarily along the northern versant of New Guinea’s Central Cordillera, with some specimens also encountered in the southeastern lowlands. However, it is uncertain to what degree the number of captured specimens of a particular phenotype is due to greater survey efforts as opposed to natural distribution patterns. The reticulated morphotype appears to be the most widely distributed Stegonotus species, and some individuals are also known from Australia, where they are relatively rare (Rick Shine, pers. comm.)., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 43, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Boulenger, G.

Stegonotus sutteri Forcart, 1953:379 Taxonomic status. This species has been considered a synonym of S. florensis since 1954, the year after its description. Based on the understanding of species boundaries in Stegonotus we have gained during our examination of hundreds of specimens, we use the following characteristics to distinguish S. sutteri from S. florensis (characters in parentheses): (1) SC ♀ = 76 (66), a difference greater than the within-species counts for SC that could be predicted using standard deviation values for confirmed species of Stegonotus; (2) internasal suture four-fifths of internasal length (two-thirds), indicating that the rostral invades the dorsal surface of the head to a much lesser degree; (3) chin area separated from true ventral scales (gastrosteges) by three or four scales along the ventral midline (five scales); (4) smaller maximum SVL of 662 mm in males (850 mm); (5) mottled brown color pattern on the body (no discernable pattern); and (6) head without color pattern (irregular and diffuse brown and cream reticulations present in the head and neck region). These, combined with a distance of ca. 300 km (by air) across the Savu Sea between Sumba and the section on Flores where S. florensis is found, and the distinction between many elements in the herpetofauna of the Outer Banda Arc, where the volcanic relict Sumba is located on a crustal fragment (Abdullah et al. 2000; Rutherford et al. 2001), and the Inner Banda Arc, where the a chain of volcanoes merged emergent landmasses to create Flores (Muraoka et al. 2002), we hereby remove S. sutteri from the synonymy of S. florensis. Synonyms. None. Original name. Stegonotus sutteri Forcart, 1953:379. Lothar Forcart (1902–1990; Fig. 17L) was a Swiss malacologist and herpetologist, with a long career as Curator at the Natural History Museum in Basel, Switzerland from 1938–1967 (Wüthrich 1990), where he succeeded Jean Roux (1876–1939). The species epithet honors the Swiss ornithologist Ernst Sutter (1914–1999), a participant in the 1949 expedition to Sumba by the Museum for Anthropology and the Natural History Museum in Basel. The species description was provided in German and included three photographs (of the entire specimen, the tail, and the everted hemipenes) and two line drawings (of the head in left lateral and dorsal views). The photograph of Forcart (Fig. 17L) is from Wüthrich (1990). Holotype. NMBA 14872 (Fig. 29; Table 1), an adult male. Type locality. “Zentralsumba, Lindiwatju 430 m ” [central Sumba Island, East Nusa Tenggara Province, Indonesia]. The specific locality “Lindiwatju” is indicated in a map of the major travel routes and sampling locations in the travelogue of the Basel museum’s Sumba expedition (Bühler & Sutter 1951: Fig. 2). However, as this village is not found on contemporary maps of Sumba Island, it requires some additional explanation. In Kapunduku, the local dialect of central Sumba, the term “palindi” is used to describe a hill or a house on a slope (Adams 1973, 1974). The term wacu (also spelled watju) means stone. The terms combined, as Palindi Wacu (or Lendiwacu on Google Maps), indicates a rocky outcropping. The location that fits the description and the map in Bühler & Sutter (1951) is at ca. 9.6556°S, 119.78°E. Collection. According to Forcart’s (1953) description, the specimen was obtained on 30 September 1949. Key characteristics of the holotype. 535 (567) mm SVL + 150 (144) mm TL = 685 (711) mm TTL. V ♂ = 231 (230), SC ♂ = 82 (83), SCR ♂ = 0.26 (0.27), D = O-21-O (21-21-19), SL E = 3+4+5 (3+4+5), SL = 9 (9), IL = 11 (10), IL G = 5 (5). Subcaudal scales are unpaired. Key characteristics of the species. We have been able to examine only three specimens of S. sutteri, two males (the holotype and WAM 101957) and one female (WAM 101680), and our species-level synopsis is therefore tentative. Based on these specimens the following characteristics apply: V ♀ = 210, V ♂ = 210–230; SC ♀ = 76, SC ♂ = 83; SCR ♀ = 0.27, SCR ♂ = 0.27; D = 21-21-19; SL E = 3+4+5; SL = 9; IL = 9 or 10; IL G = 4 or 5. There does not appear to be a difference in V between males and females, whereas the difference in SC might indicate sexual dimorphism. Of course, given the small sample size, this statement is speculative. Comment. Forcart (1953) considered his new species to be most closely related to Stegonotus plumbeus (Macleay, 1884). Only a year after its description, in a somewhat curious turn of events, he then placed it into the synonymy of S. florensis (Forcart 1954). It appears from Forcart’s (1954) explanatory text that he was prompted by the well-known and senior herpetologist Robert Mertens (1894–1975), curator at the Senckenberg Museum in Frankfurt, Germany, to rethink his description and to revise his assessment of the species., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 51, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Forcart, L.

Stegonotus poechi Werner, 1924:32 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus poechi Werner, 1924:32. Holotype. NMW 23406 (Fig. 28; Table 1), an adult female. Type locality. Written on the historic label affixed to the jar is the notation ���Neu-Guinea?��� [New Guinea?]. The specimen ledger in Vienna has no additional information. As is the case with the type locality of S. dorsalis (see above), this specimen came from the area P��ch (1908) called Monumbo, the hinterland of Potsdamhafen (ca. 4.2280��S, 144.9333��E). Collection. The label on the jar lists ���Coll. P��ch?��� [collector P��ch?], and we were indeed able to confirm based on the original accession slips that the holotype of S. poechi was collected during the same voyage, and arrived in the same shipment, as the holotype of S. dorsalis. Key characteristics of the holotype. 800 (860) mm SVL + 180+ (164+) mm TL = 1080+ (1024+) mm TTL. V ♀ = 199 (200), SC ♀ = 53+ (55+), SCR ♀ = O (O), D = O-19-O (19-19-17), SL E = 4+5+6 (4+5+6), SL = 9 (9), IL = O (10), IL G = 4 (4). Key characteristics of the species. Given that only a single specimen of S. poechi appears to exist in museum collections, our species-level characterization is necessarily very general. Stegonotus poechi has a ventral count near 200 and, due to the broken tail, we are unable to make any statements regarding its subcaudal count or relative tail length. It possesses 19-19-17 dorsals, which is a unique count in the genus Stegonotus and similar to the count featured in some individuals of S. admiraltiensis and S. iridis (17-19-15; see below). A second unique characteristic is SL E = 4+5+6, which we have not seen as either a species-level characteristic or an aberrant count in the specimens we have examined. This high value of SL E is juxtaposed by the lower value of IL G = 4, in combination with a relatively high IL count (10). Comment. To the best of our knowledge, this species has only been mentioned once in the scientific literature since its original description, in a listing of Stegonotus species by Loveridge (1948) without further information. Even though there exists only a single specimen, the unusual configuration of supralabial scales (4+5+6) and dorsals (19-19-17) indicate that this is likely not an aberrant individual but a distinct form, in light that neither of these scale patterns exist in any other specimen among the hundreds from museum collections we have examined., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 49-50, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Werner, F.

Stegonotus cucullatus (Duméril et al., 1854:376) Taxonomic status. Valid. Synonyms. Zamenophis australis Günther, 1872; Lycodon keyensis Doria, 1874; Lycodon magnus Meyer, 1874; Lycodon darnleyensis Macleay, 1877; Herbertophis plumbeus Macleay, 1884; Stegonotus reticulatus Boulenger, 1895. Original name. Lycodon cucullatum Duméril et al., 1854:376. Species descriptions at the MNHN in the days of the curatorship of André Marie Constant Duméril (Fig. 3B) included sorting and preliminary labeling by the curator, collection management and specimen work by Gabriel Bibron (Fig. 3C), and specimen work and writing by both A.M.C. Duméril and his son Auguste (Fig. 3D). As the title for their description of this taxon, Duméril et al. (1854) used the common name “ Lycodon à Capuchon” [hooded wolfsnake]. The Latin species epithet “ cucullatus ” is a literal translation of the French “ capuchon ” [hood] and was most likely chosen to reflect the contrasting body coloration, with blackish brown on the dorsum and yellowish white on the venter. The species description was presented in French. The image of A.M.C. Duméril (Fig. 3B; public domain) is from an 1845 lithograph by the French illustrator Nicolas Eustache Maurin (1799–1850), that of Gabriel Bibron (Fig. 3C; public domain) is from the posthumous (1853) engraving by Marie Firmin Bocourt (1819–1904) in the atlas to Erpetologie Générale, and that of Auguste Duméril (Fig. 3D; public domain) is an 1863 photograph by the influential French-German photographer Charles Reutlinger (1816–1881). Holotype. MNHN 3412 (Fig. 5; Table 1), an adult male. Type locality. “Hâvre Dorey, à la Nouvelle Guinée ” [Doreri Bay, West Papua Province, West New Guinea]; see Comments. Collection. The primary collectors of amphibians and reptiles on the voyage of La Coquille (1822–25) were Prosper Garnot (1794–1838) and René-Primevère Lesson (1794–1849; Fig. 3E). Garnot and Lesson were part of the medical staff aboard the Coquille on the sixth French voyage of discovery, the former hired as the main surgeon and the latter as the pharmacist, and both were placed in charge of the collection of terrestrial vertebrates (Lescure 2015). Based on the shipping records, the specimen must have been collected between 26 July and 9 August 1824 (Sclater 1886; Lescure 2015). The image of Lesson (Fig. 3E; public domain) is by the French engraver Ambroise Tardieu (1788–1841). Key characteristics of the holotype. 795 (769) mm SVL + 256 (254) mm TL = 1051 6 (1023) mm TTL. V ♂ = 208 (209), SC ♂ = 93 (91), SCR ♂ = 0.31 (0.30), D = O-17-15 (17-17-15), SL E = 4+5 (4+5), SL = 8 (8), IL = 9 (9), IL G = O (5). Our values compare well to those provided in the redescription of the specimen by Sauvage (1877). The skull of the holotype was removed for detailed examination at an unknown point in the past, which can perhaps account for some of the differences between the original measurement of SVL and our own. 6. The values printed in the original description include 30 mm for head length, 765 mm for body length, 256 mm for TL, and 1051 for TTL. Key characteristics of the species. The species name cucullatus is one of the names most commonly found on labels of museum specimens of Stegonotus, and it has been applied to Stegonotus populations all across New Guinea and Australia. As a consequence, there is considerable uncertainty over which specimens should actually be considered S. cucullatus sensu stricto, and a detailed analysis of these many specimens is still underway (see Appendix; C. Kaiser et al., in prep.). As a consequence, we are limited in our species-level assessment of S. cucullatus to stating that we expect members of this species to generally possess values of D = 17-17-15, SL E = 4+5, SL = 8, IL = 9, and IL G = 5, with relatively high ventral and subcaudal scale counts (V> 200, SC> 90). However, we caution our readers that values outside of these parameters may, but probably rarely, occur in conspecifics. The male value of SCR = 0.30 in the holotype is relatively high for the genus. Comments. There has been some confusion about the type locality of S. cucullatus. It appears that the name given as “Hâvre Dorey” by Duméril et al. (1854) was incorrectly interpreted by Cogger et al. (1983) to indicate a port location (i.e., a town). When searching gazetteers or the Internet for a coastal location with this name, the only possibility that emerges is the town of Dore on the south shore of Yapen Island, the southernmost of the islands in the Schouten Archipelago of Cenderawasih Bay. However, there are three important pieces of evidence to prove that this interpretation is incorrect. Firstly, the reports detailing the ports-of-call for the voyage of the exploratory vessel La Coquille do not mention any layovers or stops on the islands of the Schouten Archipelago (Lescure 2015). Secondly, translation of the French term hâvre into English may also indicate a bay, and the inlet properly known as Doreri Bay 7 leads to the settlement now known as Manokwari, a significant coastal town on the Bird’s Head Peninsula of West Papua Province. Thirdly, and perhaps most famously, this location was listed as comprising Dorey Harbor and Dorey Village by Alfred Russel Wallace in his groundbreaking book The Malay Archipelago (Wallace 1869). Wallace devoted part of Chapter 34 to describing the location and included it in the detailed map accompanying the book. Based on the biogeography of the region, it therefore appears that S. cucullatus could be a regional Bird’s Head endemic species with a limited range, a distinct possibility as evidenced by patterns of distribution for recently described Stegonotus species (e.g., Ruane et al. 2017), or it could be a more widely distributed species similar to the elapid Micropechis ikaheca, whose type locality is also “le havre de Doréry” (Lesson 1830 8) and whose distribution does not appear to be restricted by topography (e.g., Warrell et al. 1996: Fig. 4)., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on pages 12-14, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575, {"references":["Dumeril, A. - M. - C., Bibron, G. & Dumeril, A. - H. - A.

V ♂ = 186 (190), SC ♂ = 96 (100), SCR ♂ = 0.34 (0.34), D = O-15-O (15-15-15), SL E = O (3+4), SL = 7 (7), IL = 8 (8), IL G = O (5). (3) Paratype, AMS R115361: 630 (652) mm SVL + 210 (222) mm TL = 840 (874) mm TTL. V ♀ = 186 (191), SC ♀ = 89 (89), SCR ♀ = 0.32 (0.32), D = O- 17-O (17-17-15), SL E = O (3+4), SL = 7 (7), IL = 8 (8), IL G = O (5). (4) Paratype, AMS R115320: 648 (638) mm SVL + 235 (243) mm TL = 883 (881) mm TTL. V ♂ = 192 (194), SC ♂ = 94 (95), SCR ♂ = 0.33 (0.33), D = O-17-O (17-17-15), SL E = O (3+4), SL = 7 (7), IL = 8 (8), IL G = O (5). Key characteristics of the species. According to their specimen list, Ruane et al. (2017: Appendix) included ten specimens of S. melanolabiatus in their analysis. These included specimens from a locality in the recently (2012) formed Hela Province (1 ♀, 1 ♂; erroneously listed as from Southern Highlands Province), Simbu Province (2 ♀♀, 3 ♂♂) and Southern Highlands Province (2 ♀♀, 1 ♂). We have examined all of these specimens personally, and while there is general agreement between our data sets, there are three noteworthy differences (those of Ruane et al. are shown in parentheses). Our data show AMS R115360 with 15-15-15 (17-17-15) dorsals, AMS R 122360 with 17-17-15 (15-15-15) dorsals, and AMS R115321 with 7 (8) supralabials and 8 (9) infralabials. The data for supra- and infralabials is readily verified on our photographs of the specimens and is used for the following calculations. The two other data discrepancies are omitted because of their incongruence. Characteristics include V ♀ = 180���191 (184 �� 4.3), V ♂ = 190���201 (196 �� 4.7); SC ♀ = 89���100 (96 �� 4.9), SC ♂ = 93���100 (95 �� 3.3); SCR ♀ = 0.34, SCR ♂ = 0.33; D = 17-17-15 (n = 6, 75%) or 15-15-15 (n = 2, 25%); SL E = 3+4 (100%); SL = 7 (100%); IL = 8 (100%); IL G = 5. Based on the numbers of ventral scales, there appears to be some sexual dimorphism in that character, with females generally possessing a number of ventrals in the 180s (V mean = 184, only one female with V = 191), whereas males have ventral numbers in the 190s or higher (V mean = 196, two males with V ��� 200). There does not appear to be any sexual dimorphism in the number of subcaudal scales. Comment. Ruane et al. (2017) considered S. melanolabiatus to be a member of their S. diehli complex., Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Dum��ril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 58, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/2607575

El presente volumen ofrece un corpus del castellano hablado que consiste en 20 entrevistas realizadas en el municipio de Getxo, País Vasco. En la breve introducción se resume el marco de la investigación en la que se recogieron los datos, se describen los criterios de selección de los informantes y se explican los aspectos más importantes de la convención de transcripción aplicada. Bei dem vorliegenden Buch handelt es sich um ein Korpus des gesprochenen Spanisch. Es besteht aus 20 Interviews, die in der Gemeinde Getxo, Baskenland, erhoben wurden. In der kurzen Einleitung werden der Rahmen, in dem die Daten erhoben wurden, beschrieben, die der Informantenauswahl zugrunde gelegten Kriterien erklärt und die wichtigsten Aspekte der angewandten Transkriptionskonvention skizziert. In this volume we offer a corpus of spoken Spanish consisting of 20 interviews collected in the municipality of Getxo, Basque Country. The short introduction describes the framework within which these data were collected, explains the criteria for the selection of the interviewees and outlines the most important aspects of the transcription conventions used.

G-quadruplexes (four-stranded DNA secondary structures) are showing promise as new targets for anticancer therapies. Specifically, G-quadruplexes in the proximal promoter region of regulatory genes have the potential to act as silencer elements and thereby turn off transcription. Thus, compounds that are capable of binding to and stabilizing G-quadruplexes would be of great benefit. In this chapter we describe two recent studies from our labs. In the first case, we use NMR to elucidate the structure of a 2:1 complex between a small molecule and the G-quadruplex in the c-MYC promoter. In the second case, we use an allele-specific transcription assay to demonstrate that the effect of a G-quadruplex-interactive compound is mediated directly through the G-quadruplex. Finally, we use this information to propose models for the interaction of various small molecules with the c-MYC G-quadruplex.
