This new species is most similar to Asiophlugis philippina (Jin, 1993) from Luzon and shares similar unique characters among Asiophlugis (see Tan et al., 2020): brachypterous, and with the male tegmen being tear-shaped; the male stridulatory anatomy obscure; the presence of two long, cylindrical latero-apical processes at the posterior end of the male tenth abdominal tergite; and dark patterns on the dorsal and medial parts of some tergites. However, the new species differs from A. philippina by: the lateral processes on the male tenth abdominal tergite being more cylindrical (instead of being dorso-ventrally flattened) and pointing more dorsad and externally (instead of pointing posteriorly); the male cercus distinctly longer, slenderer and flattened, with a medial flattened tooth-like process produced along inner margin, but without any apical process; the basal process of the male cercus with spatulated apex. The female of this new species differs from that of A. philippina by the shape of subgenital plate being small and transverse (rather than long, narrowed distally with a rectangular lobe at the apex). The new species is also similar to the brachypterous Asiophlugis cercalis Gorochov, 2012 and Asiophlugis paracercalis Gorochov, 2019 from Sarawak (Borneo) in the presence of a slender male cercus with very short stout setae along its inner margin; but the cercus differs from those of the two species by the shape of the basal process and the presence of a medial flattened tooth-like process produced along the inner margin. The new species also differs from these two species by the presence of cylindrical latero-apical processes produced along the posterior margin of the male tenth abdominal tergite and the weakly visible venation on the male tegmen. The new species is also similar to Asiophlugis borneoensis (Jin, 1993) from Sabah (Borneo) in the greatly reduced male tegmen with weakly visible venation and the presence of latero-apical processes along the posterior margin of the male tenth abdominal tergite; but it differs distinctly by the slenderer latero-apical processes of the male tenth abdominal tergite and the shape of cercus. Etymology. The species name refers to the spatulated apex of the basal process of the male cercus. Description. Habitus typical of Asiophlugis, generally green when alive (and yellow when preserved), but with some brown and dark patterns on pronotum and tergites (Figs 2, 3). Eye very large with a bright red band (not always present), almost globular, somewhat longitudinally elongated (Fig. 4A). Scapus brown apically; antennal segments generally black, some with brown apices (Fig. 4A). Face high, oblique and slightly concave in profile (Fig. 4A). Pronotum dorsal disc slender and elongated, generally green; with posterior half of metazona brown (Fig. 2); having fairly straight posterior margin (Fig. 4B). Pronotum lateral lobe distinctly longer than tall; with metazona barely elevated (Figs 3, 4A). Thoracic auditory foramen small, thoracic spiracle slit (Fig. 4A). Outer and inner tympana on fore tibia open, oval and large. Fore coxa with long and thin spine which is slightly curved. Fore and middle legs generally green with tint of brown (particular around the tympana, basal and apical parts of middle tibiae) (Fig. 2). Fore femur with 4 and 1 ventral spines on the inner and outer margins respectively (outer spine at distal third distinctly shorter than inner ones). Fore tibia with 5 and 4 long and thin ventral spines on the inner and outer margins respectively. Middle leg with one tibial spine slightly after middle. Hind femur mostly green, posterior third slightly brown, black ring around knee; hind knee lobe blunt and black (Figs 2C, 3). Hind tibia brown, at the posterior end with a broad white ring, posterior of the white ring black; with only moderately numerous small spinules on both dorsal edges of tibia (Figs 2C, 3). Hind tarsus mostly black (Figs 2C, 3). Abdominal tergites generally green; some segments (especially the basal and posterior segments) with brown bands (either longitudinal along tergite length in middle, or transverse along posterior margin) and triangular black patch along posterior margin (Fig. 2). Male. Tegmina tear-shaped; transparent with anal and apical margins brown; barely surpassing beyond posterior margin of first tergite (Figs 3A, 3B, 4B). Venation and stridulatory anatomy obscure (Fig. 4B). Tenth abdominal tergite with posterior margin slightly concave in middle, with a pair of brown long latero-apical processes (Fig. 4C). Latero-apical process of tenth abdominal tergite cylindrical, long and surpassing epiproct, pointing dorsad and outward; apex obtuse and black (Figs 4C–F). Epiproct stoutly tongue-shaped; basal half slightly swollen laterally, posterior half rounded (Fig. 4D). Cercus complex: long, slender and flattened after basal third (Figs 4C, 4F). Inner basal process of cercus green and swollen basally, then black, flattened and strongly curved into spatulated apex; apex flattened, obtuse and with fine setae (Figs 4D, 4E). In middle, cercus dorso-ventrally flattened; with sparse setae very short and stout (spinule-like) along inner margin and inner-dorsal surface; with tooth-like and flattened medial process produced along inner margin. Medial process with apex brown, obtuse and with a few stout setae (Figs 4C, 4E). Before apex, cercus rotates inwards and slightly widens, with apical part more laterally flattened; with very short stout setae along inner margin; apex brown and rounded truncated (Figs 4C, 4E, 4F). Subgenital plate about as long as broad, with lateral margins rounded into posterior margin; posterior margin somewhat straight, with lateral lobe barely produced. Stylus green, fairly long and cylindrical; with obtuse apex brown to black (Figs 4E, 4F). Female (subadult) (Fig. 3C). Tegminal bud squarish (Fig. 5A). Cercus long and slender, typical of genus; apical half progressively darkened (Fig. 5B). Ovipositor also typical of genus (Fig. 5B).

Platybinthus striolatus (Brunner von Wattenwyl, 1898) gen. et comb. nov. Figs 2–3, 4A–D, 5B, E, 6B, 7A, C, 8A–C, H Paraeneopterus striolatus Brunner von Wattenwyl, 1898: 279. Lebinthus striolatus – Kirby 1906: 88. — Karny 1915: 68. — Shiraki 1930: 233. — Chopard 1968: 354. — Hsiung 1993: 26. — Ichikawa et al. 2000: 275. Diagnosis Platybinthus striolatus gen. et comb. nov. differs from P. punctatus gen. et comb. nov. by smaller size and by female copulatory papilla with apex narrowed and obtusely rounded. It also differs from Platybinthus sandyi gen. et sp. nov. by male genitalia with pseudepiphallus dorsal disk smaller, margins at the apex tapering (instead of straight) and by pseudepiphallic parameres with ventral lobe cylindrical (instead of appearing triangular and flattened).

Gorochov leg.; molecular sample L81-Lpc1; GenBank accession: OP684788 and OP686542; ZIN. Remarks The type (holotype) specimen in SMFD is a male juvenile. It is the only known specimen of the species, and probably the only specimen examined by Brunner von Wattenwyl (1898), according to the measurements that he provided. Given the general shape and colouration pattern on the legs, we hypothesise here that this juvenile belongs to the same species as the adult specimens from Halmahera found in MNHN and ZIN, and differing from the type of the species P. punctatus gen. et comb. nov. Although the evidence is weak, and not being able to sequence the old type juvenile, we refrained from describing a new species from these adult specimens; instead we propose to stabilise the name P. striolatus gen. et comb. nov. by redescribing the species based on them. As a consequence of the very brief original description and limited characters available on the type specimen, the name Lebinthus striolatus has been mentioned multiple times in databases, books and publications based on erroneous identifications of specimens of other species of Lebinthus from Taiwan (e.g., Shiraki 1930; Ichikawa et al. 2000). Those specimens and records probably correspond to one of the two species of Lebinthina documented in Taiwan, Lebinthus lanyuensis Oshiro, 1996 or Falcerminthus yaeyamensis (Oshiro, 1996), which were wrongly identified as Lebinthus striolatus based on their colouration matching the evocative ‘striolated’ name. Redescription Size small for the genus (Fig. 4A–D). Vertex and fastigium very dark brown; dorsum of head at posterior end with three longitudinal pale bands (Fig. 5B); back of eyes with a cream-coloured band. Scapes white, with some dark patterns (more in the ventral). Antennae orange brown. Fastigium verticis and frons dark grey-brown (Fig. 5E). Mouthparts whitish, mandibles grey-brown mottled with white; clypeus and labrum white; maxillary palpi with segments white with some dark stripes (more prominent on external surface) (Fig. 5E). Gena grey with a triangular white spot beneath eyes and two small white spots nearer to mouthparts. Lateral parts of head dark brown behind eyes (Fig. 6B). Pronotum dorsal disk yellow mottled with dark brown, anterior and posterior margins straight; lateral lobes very dark brown (Fig. 6B). Legs: FI–II pale with numerous dark brown spots and incomplete ring near apices, knee area dark brown; TI–II pale with three broad dark brown rings; tarsomeres 1 and 3 of each leg yellow basally then brown; FIII brown finely mottled with yellow and dark brown, knees dark brown; TIII homogeneously dark brown, spurs lighter brown with dark tips. Abdominal tergites dark brown with faint dark and light spots. Cerci brown with faint apical rings. Male FW reaching apex of third tergite. FW colouration (Fig. 7A): dorsal field cells mostly brown, plectrum area and basal area darker, with two faint pale spots at the basal and apical end of Cu and M; veins whitish or cream-coloured; M yellow brown, R orange brown. Lateral field cells dark brown in dorsal half and whitish in ventral half; longitudinal veins red brown with cross-veins cream-coloured. FW venation: harp vein bordering false mirror strongly sinuous. Anal area of dorsal field extending beyond apex lateral field, apex of dorsal field obliquely rounded. GENITALIA (Fig. 8A–C).

Genus Platybinthus gen. nov. urn:lsid:zoobank.org:act: 31113AC2-ED96-4949-95A5-E8F0879B351B Type species Piestodactylus punctatus Brunner von Wattenwyl, 1898. Diagnosis Among the genera of Lebinthina, species of Platybinthus are average to large sized with a dark brown colouration. Platybinthus is mainly characterised by male genitalia with pseudepiphallus middle part forming a dorsal ovular disk. General shape close to that of Macrobinthus and Rugabinthus, both mostly from New Guinea. Eyes prominent and large as in Macrobinthus and Rugabinthus. Microptery in both sexes, FWs not reaching mid-length of abdomen. Female FWs shorter than in males, very slightly overlapping, rounded posteriorly as in Macrobinthus and Rugabinthus. Ovipositor nearly as long as FIII; apex faintly denticulate dorsally. Copulatory papilla conical, with a wide basal sclerite and a well-developed apex slightly sclerotized and indented. Male FWs more resemble that of Macrobinthus, from which it slightly differs by main oblique vein partly differentiating a false mirror in harp posterior angle. Likewise, mirror only slightly differentiated, as in Macrobinthus. CuA clearly curved inwards posteriorly, as in Macrobinthus (almost straight in Rugabinthus). Some characters of male genitalia more resemble some species of Rugabinthus in that it is elongated and slender, its basal margin distinctly indented in the middle and the posterior apex spoon-like, without paired lophi. In contrast, Platybinthus differs from Rugabinthus by the male FWs with a shield-shaped harp (triangleshaped in Rugabinthus) and absence of strong diagonal fold carrying diagonal vein and cell c1, and separating FWs in two distinct areas (characteristic feature of Rugabinthus). The new genus also differs by hind legs distinctly longer (twice as long as body size). Etymology Genus named after the old genus name ‘ Platydactylus ’ to which several early described eneopterine species belonged, including the type species, before the name was recognised as an homonym of a genus of Squamata Oppel, 1811. Therefore we use the prefix ‘ Platy ’ (referring to Platydactylus) with the suffix ‘ binthus ’ referring to Lebinthina. Description Size medium for the subtribe (Figs 1–2, 4). Dorsum of head rounded, prolonged by rectangular fastigium distinctly wider than long (Fig. 4A–C). Head dorsum uniformly black (Fig. 5A–C). Eyes large and prominent. Head roundly triangular in facial view, almost as wide as high (Fig. 5D–F). Face finely rugulose, colouration usually cream-coloured and with lateral parts dark (Fig. 5D–F). Maxillary palpi with apical and subapical segments cream-coloured (slightly darkened apically), other segments black. Ocelli large, pale-coloured, forming a rather wide triangle; median ocellus rounded, lateral ocelli similar sized and rounded. Scapes small. Antenna with basal segments cream-coloured with tint of black, otherwise dark. Lateral part of head black with a narrow yellow band behind eyes (Fig. 6). Pronotum dorsal disk trapezoidal, on average 1.6 times as wide as long, its anterior margin distinctly emarginated in the middle, posterior margin straight, mostly black. Lateral lobes longer than wide, uniformly black (Fig. 6). Legs (Figs 1–2, 4): TI with two tympana; inner tympanum covered by a flat sclerotized expansion, its membrane visible along a small longitudinal slit only; outer tympanum ellipsoidal, its membrane transversally plicate in dorsal half. TI with two inner and two outer apical spurs. TII with two inner and two outer spurs. Hind legs very long (twice as long as body size); FIII muscular; TIII serrulated on their whole length, with four pairs of subapical spurs and three pairs of apical spurs; inner spurs long and curved, outer spurs shorter and straight. Legs I and II light brown to yellow brown, femora with brown spots and longitudinal patterns, tibiae with rings. TaIII-1 with 4–5 spines on dorsal outer edge and without any on dorsal inner edge. TIIIs and tarsomeres brown with spines and spurs with dark apices. FWs short, barely reaching abdomen mid-length; hind wings absent. Cerci well developed. Abdomen: tergites dark brown, with faint pale spots along posterior margins. Male Metanotal glands absent. Dorsal field of FWs slightly shorter than lateral field. FWs 1.4–1.6 times as long as wide, on average 1.7 times as long as pronotum dorsal disk. FW venation (Fig. 7A–B): 1A vein (file) transverse part straight, bisinuate anteriorly to angle, forming a notch in most species. Diagonal vein strong. Harp shield-shaped, with a characteristic fold, longer than wide, occupying approximately half of dorsal field surface, with a strong transverse, bisinuate harp vein, and a secondary one in anterior corner of harp. Cell c1 widened posteriorly. CuA anterior part strong throughout, slightly curved inward near apex. Mirror (d1) little differentiated from other cells of D alignment. Apical field very short, including one cell alignment posterior to mirror. Lateral field with four strong longitudinal veins ventral to Sc; Sc without projection. Subgenital plate elongated, clog-shaped. Epiproct and subgenital plate brown. GENITALIA (Fig. 8A–F). Pseudepiphallus elongate and slender, its basal margin distinctly indented in the middle; median part of pseudepiphallus forming a dorsal ovular disk dorsally; posterior apex elongated, without paired lophi, forming a median spoon-like expansion shorter than rest of pseudepiphallus. Rami short, shorter than half of pseudepiphallus length. Pseudepiphallic parameres average sized, ventral lobe strongly sclerotized. Ectophallic apodemes parallel and long, usually reaching beyond anterior margin of pseudepiphallic sclerite. Ectophallic arc well sclerotized, curved. Ectophallic fold with two ventral sclerites of variable shapes, extending posteriorly but not reaching posterior apex of pseudepiphallus. Endophallic sclerite comprising a long and straight anterior region, a short median expansion and short lateral arms posteriorly. Endophallic apodeme with well-developed lateral lamellae and a triangular dorsal median crest. Female FWs very short, not reaching base of first tergite, very slightly overlapping. Cells of dorsal field brown, dorsal field with strong orange longitudinal veins and very weak yellow transverse ones; lateral field with four longitudinal veins (Fig. 7C–D). Posterior corner between dorsal and lateral fields forming an acute angle. Dorsal field apex oblique. GENITALIA (Fig. 8G–H). Ovipositor rather short, apex faintly denticulate dorsally. Copulatory papilla conical, with a wide basal sclerite and a well-developed apex slightly sclerotized and indented. Distribution INDONESIA: Halmahera Island of Maluka and nearby island of Morotai.

Eurepa punctata – Kirby 1906: 89. — Chopard 1968: 355. Lebinthus punctatus – Robillard 2011: 58. Diagnosis Platybinthus punctatus gen. et comb. nov. differs from Platybinthus striolatus gen. et comb. nov. by larger size, and female copulatory papilla with apex narrowed and bilobed (instead of narrowed and obtusely rounded). Only faint differences of female FW venation and colouration with Platybinthus sandyi gen. et sp. nov. Material examined Syntype INDONESIA – Maluka • 1 ♀; Halmaheira [= Halmahera Island]; 1894; W.

Remark The only type specimen examined from the original type series is a female from MNHN, but male syntypes exist according to the male measurements and the drawing of male FW venation presented in Brunner von Wattenwyl (1898). Due to the lack of male characters, the comparison with other species of the genus remains limited. Molecular data obtained for the three species of the genus support the fact that they should be considered as different taxa, despite the lack of detailed information on P. punctatus gen. et comb. nov. Further information will have to be provided by future studies. Redescription Female FWs reaching middle of fourth tergite, faintly overlapping. Cells of dorsal field dark brown, not translucent, with orange strong longitudinal veins and white weak transverse ones; with 9 veins on dorsal field, 4 on lateral field.

Discotettix adenanii Mahmood et al., 2007: 1276 [original description, type locality: Borneo: Kuching]; synonymized by Kočárek et al. (2015). Type locality. According to the original description the type locality is Java, but since no locality label is present under the holotype (the only found specimen originating from Serville's collection in MNHN), we believe that the specimen originates from Borneo, from where the majority of the records of this species are. In MNCN, there are four specimens labeled ‘Java’ so it is not fully clear whether this species is/was present on Java. Borneo Island is the type locality of D. armatus, which is the type species of the genus Discotettix (a junior synonym of D. belzebuth). The type specimen of D. belzebuth was considered lost, but was found in March 2016 by JS in MNHN. For D. armatus, we believe that the specimen still exists in the Naples collection (Italy), but we were not able to contact the Museum or to get information on Costa's collection. Material examined.

All the records of D. belzebuth from iNaturalist may be found on the following link: https://www.inaturalist.org/observations?taxon_id=637240 (all records submitted by July 2022 are shown in Table 1); while for Flickr, ProjectNoah, and SpinelessWonders all the observations (Figs 6–14) are listed in the Table 1. ......Continued on the next page TABLE 1. (Continued) ......Continued on the next page TABLE 1. (Continued) Distribution. The species is widespread in Borneo (many data from Malaysian and Brunei part, but few from the Indonesian part, probably due to the lack of research) and adjacent small islands (such as Labuan). This species was previously considered widely distributed on all the Greater Sunda Islands of the Malay Archipelago, namely on Borneo, Java, and Sumatra (Serville 1838; De Haan 1843; Rehn 1904; Hancock 1907a; 1907b; Günther 1938; Mahmood et al. 2007; Kočárek et al. 2015; Tan & Wahab 2018). Distribution of the species in Java was/is possible, as in the Bolívar's collection in MNCN Madrid there are several specimens labeled ‘Java’, but its presence nowadays should be confirmed as there have been no records for more than a century. The species is not present in Sumatra (De Haan 1843), with De Haan’s (1843) records likely belonging to D. selysi, which was not described at the time. Taxonomic notes. Discotettix adenanii is considered a junior synonym of D. belzebuth. Seven well-developed pronotal projections (Mahmood et al. 2007) are the diagnostic character of D. belzebuth as well. Günther (1938) pointed out the variability of this polymorphic species with certain specimens that are not easy to identify as D. belzebuth, but as a form with certain characteristics somewhat similar to Kraengia. The description of D. adenanii, on the other hand, completely fits D. belzebuth description and diagnosis. Variability of the species can be observed solely by comparison of Bolívar's drawing (Hancock, 1907a: 6) with Günther's D. belzebuth figure (1938: p. 301, Fig. 2). Kočárek et al. (2015) examined type specimen of D. adenanii and the variability of the pronotal morphology in D. belzebuth populations collected in different parts of Borneo, showing that all the studied specimens fit the variability of D. belzebuth. We agree with the conclusion of Kočárek et al. (2015) that D. adenanii is a pure synonym of D. belzebuth. Diagnosis. This is the species with the highest (in lateral view) and spikiest/sharpest pronotal projections in the entire genus and by its general appearance it can readily be distinguished from all the other species of the genus. It is somewhat similar to D. kirscheyi Skejo, Pushkar, Tumbrinck et Tan sp. n. from NE Borneo, and to D. sumatrensis Skejo, Pushkar et Tumbrinck sp. n. from Sumatra. From D. scabridus the new species can be separated by the following characters: (I) bifurcation of the frontal costa between the eyes (on the lower margin of the compound eyes in D. scabridus), (II) FM high and developed (present as a small tubercle in D. scabridus), (III) MM elevated into spines (lower and saw-like in D. scabridus), (IV) MML elevated into spines (present as low and triangular, compressed elevations in D. scabridus), (V) ML strong and long, tooth-like (absent in D. scabridus), (VI) interscapular area with parallel margins (wide and triangular in D. scabridus). Discotettix belzebuth can be separated from D. selysi, D. doriae, and D. aruanus Skejo, Pushkar et Tumbrinck sp. n. by the following characters: (I) more than one well-developed protuberance on the pronotal disc, (II) long frontomedial projection of the anterior margin of the pronotum, (III) fore and mid femora are more slender, (IV) antennal segments are more specialized in morphology than in D. selysi, the widest and the most flattened is the 10 th segment (unlike the 9 th segment in D. selysi and D. doriae). From D. sumatrensis Skejo, Pushkar et Tumbrinck sp. n. the species can be easily separated by the following characteristics: (I) larger body size, (II) all antennae segments are of black/dark color, (III) the 8 th antennal segment is the widest one (unlike the 7 th segment in D. sumatrensis Skejo, Pushkar et Tumbrinck sp. n.), (IV) the hind femur bears small lappets. D. kirscheyi Skejo, Pushkar, Tumbrinck et Tan sp. n. can be easily separated from D. belzebuth by the following set of characters: (I) in D. kirscheyi Skejo, Pushkar, Tumbrinck et Tan sp. n. antennae with more robust segments gradually become wider distally, not as specialized as in D. belzebuth, (II) D. kirscheyi Skejo, Pushkar, Tumbrinck et Tan sp. n. has short FM, not covering the whole head as in D. bellzebuth, (III) projections on the dorsal surface of the pronotum are smaller in D. kirscheyi Skejo, Pushkar, Tumbrinck et Tan sp. n., (IV) D. kirscheyi sp. n. has weak ML, (V) D. kirscheyi sp. n. has robust and serrated fore and mid femora, not as slender as in D. belzebuth and (VI) D. kirscheyi sp. n. has smaller body size. Redescription. General characters. Medium to large sized, robust, species (13.01–17.02 mm), texture granulated, rugose; pronotum wrinkled, with numerous small tubercles, medium-sized and large protuberances on dorsal and lateral sides. Epizoic symbiotic bryophytes and algae are often present on the pronotal surfaces, so usually the specimens are characterized by cryptic colors (Figs 8, 10). Macropronotal. Coloration. Coloration variable: from black and dark brown to brighter tints of brown: grayish, greenish, yellowish, reddish, somewhat purple; pronotal projections usually darker. The entire body, including antennae, may be of the same color, except brightly colored frontal carina on the head and the median carina of pronotum, while fore and mid tibiae and tarsi usually bear 1–3 lighter rings. Maxillary palpi black with pale colored joints between the segments (Figs 5–14). Head. In dorsal and frontal view, vertex 2.21–2.76 times as wide as an eye. Fossula elliptic and deep. The lower margin of the lateral ocelli a bit below the level of the lower margin of a compound eye. In frontal view, frontal costa narrow, bifurcated above lateral ocelli into subparallel, finely granulated facial carinae forming a very narrow scutellum. Scutellum slightly narrower than the antennal groove. Antennal groove below the lower margin of the compound eye (Fig. 5C). Antenna with 13 antennomeres. A detailed description of the antennal morphometrics and morphology was published recently by Kuřavová et al. (2017). Antennal segments as follows: scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 6 th) elongated and circular in cross-section; central or subapical segments (7 th and 8 th) strongly widened, pennate, 8 th being the widest antennal segment (in holotype 2.22 times as long as wide); apical segment 9 th much smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bearing saw-like margins, because of the presence of large basiconic sensilla (Fig. 10). When the body and the antennae are covered with algae and moss, the 8 th segment is always free of epizoic organisms (Fig. 10). Pronotum. Pronotum wrinkled and granulated, covered in numerous small tubercles and larger projections. The posterior process of the pronotum slender, surpassing the hind knee for about half of the hind femur length. Disc of the pronotum at almost the same level along all length, and unlike other species of the genus, without a distinct depression behind the shoulder. Pronotum not descending backward. Morphology of the pronotal disc variable, usually with 4–7 unpaired projections of variable size on the median carina (FM, PM, and 2–5 MMs); 2–3 pairs of FL; 4–7 pairs of more or less distinct PMLs and MMLs; 3 pairs of PLs and MLs; and a pair of VL. Prozona short, subsquare. The anterior margin of the pronotum projected as a large digitate FM directed upwards and forwards above the head, covering the whole area of the fastigium of the vertex. FM often decurved with excised apex. Prozonal carinae slightly elevated, surpassing the anterior margin of the pronotum as dentiform FL1. Extralateral carinae elevated, surpassing anterior margin of pronotum as dentiform FL2. FL3 dentiform, small and weak, more distinct than FL1. Median carina extended along the whole length of the pronotum, tuberculated, but with smooth areas. Median carina bearing FM and 3–6 of large digitate medial projections well seen in profile. PM small, distinct in about a third of the examined specimens. MM1, MM2, MM3, and MM4 large and digitate (MM1MM3>MM4). MM4 well visible in most of the specimens, but in some completely reduced. MM5 present as a spike in about every tenth specimen, but usually very small and almost invisible. Among mediolateral projections, PML1 is a small tubercle, almost indistinct; PML2 small; MML1 small; MML2 large; MML3 and MML4 distinct in a few examined specimens. PL1 and PL2 elongated, small, and almost indistinct. In the metazona humero-apical carinae forms a sharp humeral angle, projected outwards as strong spine-like or digitate ML. Interhumeral carinae hardly observable because of numerous net-like elevations and tubercles present in the whole disc. The apex of pronotum blunt, and shallowly excised. The lower part of the lateral lobe with finely serrate anterior and coarsely serrate posterior margin, elongated as VL of variable shapes from sharp spine-like to saw-like form, directed strongly outwards or in rare cases somewhat backward (Fig. 5A, B). Wings. The visible part of tegmen elongated and oval. Hind wing long, often not reaching the pronotal apex. Legs. Femora more or less robust, and compressed laterally, but elongated in comparison to other species. The rough surface of the legs usually bears outgrowths and tubercles of variable size and sharpness. The dorsal and ventral margins serrate. Genicular teeth visible on all the knees, and additionally 1–3 weak teeth present on the dorsal and ventral margins of the fore and mid femora. Hind femur with small lappets on both dorsal and ventral margins. Lateral area of the hind femur with net-like elevations and weak carinae, ventro-external carina with teethlike outgrowths. Genicular teeth of the hind femora larger than the antegenicular. Both sides of the dorsal margin of the hind tibia finely serrated, additionally with 4–5 outer and 3–4 inner larger teeth. Abdominal apex. Female subgenital plate with a triangular protrusion in the middle of the posterior margin. Ovipositor of variable shapes, usually elongated, but can be more robust, probably due to the ecological factors. Measurements.

Type locality. Indonesia: Sumatra: Mentawai: Sipura Island Material examined. Type material. LECTOTYPE (Fig. 18) 1♀ Mentawei: Sipora, Sereinu [= Indonesia: Mentawai: Sipura island] V.–VI.[18]84. Leg. E. Modigliani (MCSN); PARALECTOTYPE 1♀ Mentawei: Sipora, Sereinu [= Indonesia: Mentawai: Sipura island] V.–VI.[18]84. Leg. E. Modigliani (MNCN). Distribution. This species inhabits the rainforest of the small island of Sipura (845 km 2), the smallest of the four large islands of the Mentawai Archipelago, west of Sumatra. Only two females of this species have been known hitherto. Diagnosis. This species is morphologically similar to D. selysi from Sumatra and the Malayan peninsula and to D. aruanus sp. n. from the Aru Islands because of the presence of low projections, or absence of the high ones, flat dorsum of the pronotum, and coloration. It seems to be closely related to D. selysi, but can be easily recognized from the latter by the following set of characters: (1) FM small and narrow, covering vertex only partially (in D. selysi it is large, long, and covering entire vertex), (2) smaller body size (females have a slightly shorter body and pronotum than the ones of D. selysi), (3) shorter and stouter antennae with swollen 6 th, 7 th and 8 th antennal segments (no swollen segments in D. selysi), and (4) stronger teeth of the fore and mid femora. From D. aruanus sp. n. from Aru Island, which also seems related to D. selysi and D. doriae, D. doriae can be easily told apart by the much smaller FM (large and reaching in front of the head in D. aruanus sp. n.), and much stouter and more armed fore and mid femora (less armed in D. aruanus sp. n.). From D. sumatrensis sp. n. inhabiting neighboring Sumatra, the species can be separated by (1) dark antennae with stouter antennomeres, (2) lower projections, especially FM and MMs, (3) larger body size (approximately 2 mm longer), and (4) stouter femora. For comparison with other species (D. belzebuth and D. kirscheyi from Borneo and D. scabridus from the Philippines), please consult the diagnosis of D. selysi, where a comparison to all the species of the genus Discotettix has been given, as well as the detailed diagnoses of D. scabridus and D. belzebuth containing comprehensive comparisons. Redescription. (Fig. 18) General features. Medium-sized (about 15 mm), robust species. Body finely granulated; pronotum rugose, with numerous small tubercles and net-like elevations, in parts smooth and without tubercles, anterior part of the pronotum bearing a few larger protuberances (Fig. 18). Macropronotal. Coloration. Body dark brown. Carinae and projections darker than the rest of the body. Median pronotal carina with orange patches. Antenna dark brown, without pale colored parts. Maxillary palpi dark brown. The visible part of the tegmen dark brown and without any pale spots. Legs brown except for the pale rings on tibiae and tarsi. The body probably covered with epizoic symbionts, just as in other species, giving an animal greenish camouflage when alive, after preservation in alcohol and/or drying the green color disappears. Head. In dorsal and frontal view, vertex 2.21–2.36 times as wide as the eye. Lateral carinae raised and granulated. Fossula deep. Lateral ocelli situated just below the level of the lower margin of the compound eye. Antennal groove significantly below the lower margin of the compound eye. In frontal view, frontal costa bifurcated into facial carinae, forming a scutellum with narrow and parallel borders, bifurcation just above the level of lateral ocelli. Antennal groove slightly wider than frontal costa. Antenna 13-segmented, all segments robust in comparison to other species of the genus: scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 5 th) robust, less elongated than in other species of the subgenus Discotettix, and circular in cross-section; basal segment 6 th widened and swollen; central or subapical segments (7 th and 8 th) strongly widened, pennate and swollen, 8 th being the widest antennal segment (about 2.6 times as long as wide); apical segment 9 th elongated and pennate, but smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bearing saw-like margins, but weaker than in the other species of the subgenus (Fig. 18C). Pronotum. Pronotum rugose, granulated, with numerous tubercles and net-like elevations, somewhere smooth and without tubercles (some parts of the pronotal disc and parts of the median carina of the pronotum). The anterior margin of the pronotum bearing a medium-sized FM, smaller than in the other species of the subgenus Discotettix. The posterior process of the pronotum surpassing the hind knees for at most a half-length of a hind femur. Disc of the pronotum with a small depression between the tegminal bases, then slightly elevated again. Caudad, pronotum gradually descending backward. Net-like elevations of omnipresent on the pronotal disc, all along the median carina of the pronotum and connecting it to all other carinae and the projections of the dorsal surface of the pronotum. Netlike elevations very distinct in the interhumeral region of the disc. The median carina of the pronotum continuous from the anterior margin to the pronotal apex, undulated irregularly because of the projections. The median carina of the pronotum bearing four unpaired projections of variable size: medium-sized digitate FM, directed upwards and forwards and covering the fastigium of the vertex (but not completely); PM small and triangular; MM1 large and triangular; MM2 and MM3 evident, but decreasing in size caudad, MM4 reduced. Prozona subsquare. Prozonal and extralateral carinae in prozona distinct, surpassing anterior margin of pronotum as dentiform FL1 and FL2, with FL2 more distinct. FL3 dentiform, small, and weak. Among the mediolateral projections PML1 more or less distinct; PML2 very small; MML1 small; MML2 large; MML3 v ery small; MML4 and MML5 wanting. PL1 and PL2 present as small triangular tubercles forming posterior elongation of the extralateral carinae in the line joining the humero-apical carinae. Humeral angle obtuse with pointed apex. ML present, but reduced. Pronotal apex narrow, shallowly excised. The lower part of the lateral pronotal lobe with serrate anterior and posterior margins, elongated as spine-like VL, directed strongly outwards and backward (Fig. 18A, B). Wings. Tegmina and alae present and visible. The visible part of tegmen elliptical, granulated, and tuberculated. Hind wing not reaching apex of pronotum, a few millimeters of length are lacking to touch the tip. Legs. Fore and mid femora robust, compressed laterally, dorsal and ventral margins serrated; with genicular tooth on the knees and additionally with two to three sharp teeth on the dorsal and ventral margin. Mid femora with stronger teeth than the fore femora. Hind femur with lappets, and a small protuberance situated on the ventral external carina. The genicular tooth large, while the antegenicular one small. Both sides of the dorsal margins of the hind tibia finely serrated, with 3–4 outer and 1–3 inner large teeth. Abdominal apex. Female subgenital plate in ventral view with a triangular protrusion in the middle of the posterior margin. Ovipositor robust, dorsal valvae robust, ventral slender, and serrate.

Tribe Discotettigini Hancock, 1907 stat. resurr. Discotettigiae: Hancock 1907a: 5; 1907b: 213; Willemse 1930: 4, 7; Günther 1938: 301. Discotettigini: Kevan 1966: 380. Discotettiginae: Steinmann 1970: 216; Storozhenko 2013: 158; Tumbrinck 2014: 349. Discotettinae: Otte 1997: 32; Mahmood et al. 2007: 1275. Discotettigidae: Liang & Zheng 1998: 23; Zheng 2005: 15; Deng et al. 2007: 400. Type genus: Discotettix Costa, 1864. Differential diagnosis. The tribe Discotettigini is a sister tribe to Scelimenini; their representatives share many apomorphies inherited from the common ancestor. The main difference is the shape of the pronotum (elongated, flat, and hydrodynamic in Scelimenini; and robust, wrinkled, and cryptic in Discotettigini; Rebrina et al. in preparation), as well as the shape of the fore and mid femora (elongated in Scelimenini, short and toothed in Discotettigini), and the shape of the hind tibia and tarsi (widened into a paddle in Scelimenini, while of regular shape in Discotettigini). Scelimenini members have shorter projections of the pronotal disc in comparison to Discotettigini members. Discotettigini are mostly corticolous, and Scelimenini members are mostly amphibious grasshoppers (e.g., Muhammad et al. 2018). Description. Head. Antenna with 11–15 antennomeres, filiform or with widened preapical segments (Fig. 1). Frontal costa visible above the bifurcation; the bifurcation and the lateral ocelli placed low, between the compound eyes, in line with the lower margin or visibly below the compound eye; the antennal groove located below the lower margins of the compound eyes; lateral carinae of the vertex more or less elevated; anterior margin of the vertex truncated, slightly indrawn from the level of the outer margin of the compound eyes; fossula present; medial carina of the vertex visible in the upper third cephalad (Fig. 5C). Pronotum. Prozonal, extralateral, median, humeral and lateral carinae present; interhumeral carinae present, but sometimes not visible because of the pronotal projections in their place. Pronotum strongly granulated and wrinkled, armed with numerous strong projections (FM, FL, PM, MM1, MM2, MML1, MML2, and ML) that can be of different shapes and sizes: low, high, and wart-like or high triangular, saw-like, or spine-like protuberances. Paranota triangular, laterally projected, usually bearing strong VL projection, sometimes without a spine (Figs 2, 5A, B). Legs. Dorsal and ventral margins of all the legs with small, medium-sized, or large teeth. Tibiae rectangular in cross-section, not widened into the paddles. The dorsal margin of the fore and mid femora carinated. Hind tarsi not widened into a paddle (Fig. 29B). Composition and distribution. The tribe gathers corticolous Scelimeninae genera with an undulated pronotum, and without widened hind tibiae. Altogether, 10 genera and 68 species are herewith assigned to this tribe, and these are Austrohancockia (19 species in PR China, China, and Taiwan), Bidentatettix (2 species in PR China), Disconius gen. n. (1 species in Borneo) Discotettix (7 species in Peninsular Malaysia, Sumatra, Borneo, Mindanao, Aru), Eufalconius (1 species in Peninsular Malaysia), Gavialidium (2 species in Sri Lanka and Southern India), Gibbotettix (13 species in PR China), Kraengia (1 species in Sulawesi), Paragavialidium (14 species in PR China), and Tegotettix (8 species in Indochina, Borneo, Philippines, Sulawesi, New Guinea) (Muhammad et al. 2018, this study)., Published as part of Skejo, Josip, Pushkar, Taras I., Kasalo, Niko, Pavlović, Marko, Deranja, Maks, Adžić, Karmela, Tan, Ming Kai, Rebrina, Fran, Muhammad, Amira Aqilah, Abdullah, Nurul Ashikin, Japir, Razy, Chung, Arthur Y.

Discotettix (Mnesarchus) scabridus: Kevan 1966: 380 [new records]. This is the type species of the subgenus Mnesarchus and the only species presently assigned to this subgenus. The species diagnosis and the description may hence be used as subgeneric diagnosis and description of Mnesarchus. Type locality. The Philippines (without exact locality). Lectotype designation. The lectotype for this species is designated herewith, that being the female deposited in NHRS, under the inventory number NRM-ORTH 00112879, designated by J. Tumbrinck. The lectotype bears the red label ‘lectotypus’. Lectotype designation is important because of the future analysis of intraspecific differences among D. scabridus populations in Mindanao and other islands that could result in the discovery of new species or subspecies. Since Tetrigidae species are usually morphologically well-defined, the lectotype may provide a basis for the identification of the nominotypical and/or already described taxon. Material examined.

This species inhabits the Philippines, where it has been reported from the islands of Mindanao, Samar, and Luzon. Numerous records from Mindanao, while few from Luzon might indicate that the species has higher abundance in Mindanao. Subgeneric diagnosis of Mnesarchus and specific diagnosis of Discotettix scabridus . The species is morphologically very different from other Discotettix members and is thus assigned to its own subgenus, Mnesarchus. It can be easily separated from other species of the genus by the set of the following characters: (I) frontal costa bifurcates on the lower margin of the compound eyes (bifurcation is in the lower third of the compound eyes in D. aruanus sp. n., D. belzebuth, D. doriae, D. kirscheyi sp. n., D. selysi, and D. sumatrensis sp. n.), (II) FM present as a low tubercle (developed and elevated in D. aruanus sp. n., D. belzebuth, D. doriae, D. kirscheyi sp. n., D. selysi, and D. sumatrensis sp. n.), (III) MM laterally compressed and elevated (spine-like in D. belzebuth, triangular protrusions in D. sumatrensis sp. n., D. kirscheyi sp. n., while very low in D. aruanus sp. n., D. doriae and D. selysi), (IV) MML low and triangular, compressed elevations (spine-like in D. belzebuth, triangular protrusions in D. sumatrensis sp. n., similarly formed in D. selysi), (V) interscapular area triangular, with large concavity (similarly to D. selysi, and D. sumatrensis sp. n., almost parallel in D. belzebuth), (VI) lateral and humeral carinae strongly toothed (similar to D. belzebuth, granulated in D. selysi, and D. sumatrensis sp. n.), (VII) weak ML (almost absent in D. scabridus, while well visible in other species), (VIII) VL complex, with a few spines (in other species usually with one main spine, and a saw-like margin) and (IX) tegmen more elongated (TL/TW > 5) than in other species of the genus (TL/TW Redescription (Fig. 33). General features. Medium-sized flattened species (body 12.3–12.75 mm) (15–17 mm cited in the original description, but in this measurement, pronotum was probably included as well), relatively robust in dorsal view. The entire body finely granulated, rugose; pronotum wrinkled and with numerous small tubercles and medium-sized projections. Macropronotal form. Coloration. Body color from almost black, dark brown, and ferruginous brown to yellowish-brown. Pronotal protuberances usually colored in different colors (black, reddish, yellow, whitish) and often different in color from the rest of the pronotal surface. Antenna with pale colored joints between the antennomeres; scapus, pedicel, basal and medial segments dark brown, while subapical and apical even darker. Maxillary palpi dark brown, sometimes with even darker distal margins of the last segments. The visible part of the tegmen dark brown, without spots. Tibiae and tarsi with unclear pale colored rings. Head. In dorsal and frontal view, vertex 2.4–2.65 times as wide as the eye. Lateral carinae of the vertex granulated. Lateral ocelli situated at the level of the lower margin of the compound eye. In frontal view, frontal costa narrow, bifurcating a bit above the lateral ocelli into slightly divergent facial carinae forming a very narrow scutellum.Antennal groove slightly wider than the scutellum, situated just below the lower margin of the compound eye (Fig. 33C). Antenna 13-segmented (in male seems 12-segmented, because 13 th segment very small and not visible under an optical microscope, only under SEM): scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 6 th) elongated and circular in cross-section; central or subapical segments (7 th and 8 th) widened, weakly pennate, 7 th and 8 th antennal segments almost equal in width (2–2.4 times as long as wide); apical segment 9 th elongated, but much smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bear weak saw-like margins (weaker than in the other species of the genus), because of the presence of large basiconic sensilla. Antennomeres of D. scabridus are less significantly widened than in other species of the genus and less saw-like in appearance, supposedly because of fewer or smaller basiconic sensilla. Pronotum. Pronotum wrinkled and granulated, covered in numerous small tubercles, medium-sized and large triangular protuberances. The posterior process of the pronotum slender, surpassing the hind knee for about half the length of the hind femur (macropronotal form). Disc of the pronotum a bit depressed behind the well-developed shoulder, gradually descending backward. Pronotum with 5 unpaired projections of variable size on the medial carina (FM, PM and 3 MMs), three pairs of FLs, two pairs of more or less distinguished PMLs, and two of MMLs; three pairs of lateral and a pair of VL (well visible in profile). Anterior margin of the pronotum truncated, with small FM directed upwards. FM considerably lower than in the other species of the genus. Prozonal carina elevated and decurved caudad in the direction of the median carina, in females projected anteriorly as a small dentiform FL1. Extralateral carinae distinct in males, saw- or fan-like and elevated along the entire length much more than the prozonal carina, surpassing the anterior margin of the pronotum as a dentiform FL2. FL3 weak, but distinct. Prozona of variable length, from subsquare to wider than long, but still very short when compared to other species of the genus. Behind the FM median carina extended along the whole length of pronotum. PM larger than FM, and MM1 larger than PM1. MM2 medium-sized in males or small in females. MM3 lies in the middle of pronotum length, in females as large as PM, while in males smaller. MM4 small and indistinct. PML1 and PML2 very small. MML1 small, situated between the shoulders. MML2 large. MML3 very small, better visible in females than in males. MML4 almost indistinct in both sexes. PL1 and PL2 small and triangular tubercles between the sulci on the line joining the extralateral carinae and the humero-apical carinae. ML reduced, almost absent. The apex of the posterior pronotal process very narrow, and rounded; in females weakly excised. The posterior part of the pronotal process (about a fifth of the pronotum length) directed slightly upwards or in the level of the rest of the pronotum. The lower part of the lateral lobe with serrate margins (2–3 larger teeth on the posterior margin, and numerous smaller teeth on the anterior margin), elongated as strong spine-like VL directed outwards and slightly forwards (Fig. 33A, B, D, E). Wings. The visible part of the tegmen shaped quite elongated oval, lower side slightly curved. The tegmen is not always visible. Based on the photographs, it is hard to say whether tegmina are visible or not, in both sexes they can be noticed only after careful examination under the stereomicroscope. Hind wing present, visible under pronotum, not reaching the apex of the pronotum. Legs. Femora robust and compressed laterally. Dorsal and ventral margins of the fore and the mid femora roughly serrate, with genicular tooth on knees, and additionally with 1–3 strongly projected teeth on each margin. Teeth of ventral margin projected outwards and downwards. Hind femur with small teeth on the dorsal and ventral margins; one large tooth projected outwards situated on the ventro-external carina. Genicular and antegenicular teeth small, but recognizable. Both sides of the dorsal margins of the hind tibia finely serrated, additionally with 5–8 outer and 2–4 inner bit larger teeth. The first tarsal segment of the hind leg slightly longer than the third segment. Abdominal apex. Ovipositor elongated. Measurements.

Genus Discotettix Costa, 1864 Discotettix: Costa 1864: 59; Bolívar 1887: 306; Rehn 1904: 670; Hancock 1907a: 6; Hancock 1907b: 213; Kirby 1910: 2; Willemse 1930: 7; Steinmann 1970: 216; Blackith 1992: 46; Yin et al. 1996: 866; Otte 1997: 32; Mahmood et al. 2007: 1275; Ko&ccaron;árek et al. 2015: 288–294. Mnesarchus Stål, 1877: 55; synonymized with Discotettix by Bolívar (1887). Type species: Discotettix armatus Costa, 1864, by original monotypy, a junior synonym of Discotettix belzebuth (Serville, 1838). Nomenclatural note. Many authors recently treat tettix as a noun originally of feminine gender. It is incorrect, as in all the Ancient Greek dictionaries the noun “ tettix, tettigos or tettikos, ho ” is of masculine gender. The word “ tetrix, tetrigos, he ” is however of feminine gender in Ancient Greek. Latreille (1802) introduced the name Tetrix (vernacular tétrix), but did not explain why he used the Ancient Greek name of a bird (tetrix is the Ancient Greek name of the Pipit, still present in the name of the Black Grouse Tetrao tetrix). Since then, the name Grouse Locust has been coined in the US, while the vernacular name pygmy grasshoppers has become more widely used. Even if Latreille did not want to relate pygmy grasshoppers to the bird and randomly invented the word “ tetrix ”, he used the word as feminine gender, which has to be followed (ICZN 1999, Art. 30.1.4.2). Tettix is a masculine Ancient Greek word for grasshopper, introduced by Berthold (1827) as an (unjustified) emendation of Latreille’s name. The epitheta of all the Tetrigidae species whose genus is coined out from the word tettix should be in the grammatic masculine gender. Diagnosis. The genus can be distinguished from all the other genera by the following set of characters: (I) frontal costa bifurcates between the lower third of the compound eye height (bifurcates below the lower third in other Discotettigini), (II) scutellum narrower than scapus (of the same width or wider in Gavialidium, Paragavialidium, and Tegotettix), (III) antenna 13-segmented (15-segmented in Gavialidium, Paragavialidium, and Tegotettix), (IV) subapical antennal segments widened (filiform in most of Discotettigini), (V) margins of the antenna saw-like (smooth in most of other Discotettigini). Comparison to former Discotettiginae genera. Among the former Discotettiginae genera (see Skejo 2017) the genus is similar to Kraengia and certain members of the genus Hirrius, i.e., H. montanus Günther, 1937 and H. sarasinorum Günther, 1937 from Sulawesi. Discotettix is similar to Kraengia in the general arrangement of pronotal protuberances (FM, FLs, MM, ML). However, in Discotettix the lower part of the lateral pronotal lobe is directed outwards forming a spine-like VL projection, while in Kraengia the lower part of the lateral pronotal lobe has a truncated margin. ML is more or less distinct in Discotettix species, while fully reduced in Kraengia, the humeral angle being obtuse. Additionally, Discotettix can be distinguished from Kraengia by the following set of characters: (1) 13 antennal segments (11 in Kraengia), (2) large body size (more than 11 mm in Discotettix, less than 9 mm in Kraengia), (3) presence of tegmen and wing in all Discotettix species (Kraengia is wingless), and (4) distinct prozona with carinae (in Kraengia prozona is very short and carinae are usually not distinct). Discotettix can be distinguished from Hirrius montanus and H. sarasinorum by the following characteristics: (1) dorsal surface of the pronotum with protuberances and projections (in Hirrius the pronotum is almost flat, medial, mediolateral, and lateral projections are considerably reduced in size, hump-like or fully absent); (2) the lower part of the lateral lobe of the pronotum forms a sharp spine-like or saw-like VL projection (VL spine wanting or weak in Hirrius); (3) tegmen and wing visible (not visible in Hirrius). Comparison to similar Scelimeninae: Discotettigini genera. The genus is morphologically similar to other Discotettigini genera, especially winged Bidentatettix, Disconius gen. n., Gavialidium, Eufalconius, Paragavialidium, and Tegotettix. Of all the mentioned genera, Discotettix is most similar to Disconius. From all the genera except for the Disconius, Discotettix can be easily distinguished by the widened antennomeres, while from Disconius it can be distinguished by the visible FM (reduced in Disconius), by tuberculated median carina (continuous in Disconius) and by strong FLs (almost absent in Disconius). Redescription of the genus Discotettix General features. Medium and large sized species, robust in appearance. All the surfaces rough and granulated, rugose; pronotal disc wrinkled with numerous small tubercles and protuberances of different sizes and shapes. Macropronotal. Coloration. Body color dark brown, ferruginous brown, or with brighter tints of brown; pronotal projections darker or differently colored than the rest (e.g., reddish or yellowish). Antenna black or dark brown, sometimes with pale-colored joints between the segments or with yellowish apical segments. Maxillary palpi dark brown, sometimes with darker distal margins of the last segment, or black with pale-colored joints between the segments. The visible part of the tegmen dark brown without spots. Legs dark brown except more or less distinct pale rings on tibia and tarsi and whitish 1 st tarsal pads. Head. Head not elevated above the pronotum in lateral view. In dorsal view, the fastigium of the vertex considerably broader than a compound eye; the anterior margin of the fastigium truncated, widely excised, with protruded medial carina of the vertex, reaching not far from the anterior margin of a compound eye. In frontal view, the vertex slightly concave, indrawn from the considerably raised lateral carinae on the level of the upper margin of a compound eye; the medial carina of the vertex distinct in the anterior part of the vertex. Fossula present. Supraocular lobe absent. Lateral ocelli at the level of lower margin or between the compound eyes. Median ocellus far below the level of the lower margin of a compound eye, just between the facial carinae in the place where they end. Antennal groove just above the median ocellus, below or on the level of the lower margin of a compound eye. Frontal costa narrow, with the bifurcation a bit above or between the lateral ocelli. Frontal costa bifurcates into slightly divergent facial carinae forming a narrow scutellum, in lateral view with two concavities: the first large between the lateral ocelli and the second smaller below the antennal grooves. Maxillary palpi flattened. Compound eye in frontal view subglobular, in lateral and dorsal view drop-like, not protruding above the pronotum in lateral view. The occipital area between the eye and the anterior margin of the pronotum narrow, partly visible (more often not) from above (Fig. 5C). Antenna 13-segmented (but in male looks like 12-segmented, because 13 th segment very small and not visible under an optical microscope, only under SEM). Antennal segments as follows: 1 st massive scapus; 2 nd large pedicel; 3 th to 6 th basal elongated antennomeres; 7 th and 8 th central or subapical antennomeres, widened; apical 9 th small; 10 th to 13 th apical segments small, very reduced in comparison to others (Fig. 1). Pronotum. Pronotum wrinkled and granulated, covered by numerous small tubercles and larger projections. Posterior process of the pronotum slender, surpassing the hind knee for about a half of the hind femur length or more (macropronotal); covering the whole abdomen. Disc of pronotum: 1) more or less depressed behind the well-developed shoulder and gradually descending backward, or 2) almost at the same level along all length, without distinct depression behind the shoulder, and not descending backward. General arrangement of pronotal disc projections: pronotum with 4–7 unpaired projections of variable size on the medial carinae (FM and 3–6 medial projections); 1–3 pairs of FL projections; 1–7 pairs of more or less distinguished mediolateral projections; 1–3 pairs of lateral and a pair of more or less distinct VL (better seen in profile). In some species, some of the projections lacking or reduced. Prozona subsquare or wider than long (not taking into account FM). Anterior margin of pronotum truncated or projected, with a small or a large FM directed mainly upwards or forwards, sometimes covering a part of or the whole vertex. Prozonal and extralateral carinae in the prozona distinct, more or less elevated, surpassing the anterior margin of the pronotum as dentiform FL1 and FL2, where FL2 more distinct. FL3 dentiform, small and weak, sometimes indistinct. Median carina behind FM extended along the whole length of the pronotum, with 3–6 unpaired medial projections 4 of variable size, more or less distinct (seen very well in profile). PM small and triangular. MM1 large and triangular. MM2, MM3, and MM4 decreasing in size towards the apex of the pronotum (sometimes MM3 and MM4 reduced). MM5 present only in a few specimens of D. belzebuth. Usually, 1–7 pairs of the mediolateral projections increase in size towards MML1 (largest) and then decrease towards the tip of the pronotum (PML1 < PML2 < MML1 > MML2 > MML2 > MML4 > MML5). PML1 more or less distinct; PML2 distinct; MML1 small; MML2 large; MML3, MML4, and MML5 small, decreasing caudad (sometimes 1–3 of these posterior projections reduced). PL1 and PL2 small and triangular. ML more or less sharp, usually projected outwards. Interhumeral carinae indistinct, weak. External lateral carinae raised upwards above the base of the tegmen, in the posterior half smooth, not reaching the apex of the pronotum. Internal lateral carinae smooth, weak, usually indistinct. The infrascapular area triangular, as wide as the mid femur, fused to the lateral area. Lateral area narrower than the infrascapular and running towards the apex of the pronotum. The apex of the posterior pronotal process in the dorsal view shallowly excised or rounded. Hind margin of the pronotal lateral lobe bisinuate, ventral sinus deep, tegminal sinus small. The lower part of the lateral lobe with serrate anterior and posterior margins. VL elongated as spine-like, directed strongly outwards, sometimes forward or even slightly backward, but never downward (Figs 2, 5A, B). 4 The description of medial, mediolateral and lateral projections is given in the order from the anterior to the posterior part of the body. Wings. The visible part of the tegmen oval and elongated. Hind wing with scalloped inner margin, usually shorter than the pronotal process, not reaching its apex. Legs. Femora robust, compressed laterally; with smooth or rough surface; dorsal and ventral margins finely or roughly serrate (Fig. 29B); genicular teeth visible on the knees; additional one to three teeth present on each margin. Fore and mid tarsi with distal segments longer than the proximal ones. Both sides of the upper margin of the hind femur finely serrated with distinct or indistinct lappets. Lateral area of the hind femur bears weak carinae with net-like elevations and outgrowths, especially on the ventro-external carina. Genicular teeth equal to or larger than the antegenicular. Hind tibia in dorsal view very slightly widened in basal and apical part. Both sides of the dorsal margin of the hind tibia finely serrated, usually with a few outer and large inner teeth. 1 st tarsal segment of the hind leg longer than 3 rd (without claws); 1 st and 2 nd basal pads of 1 st tarsal segment short and triangular, 3 rd (apical) elongated (Fig. 1). Abdominal apex. Male subgenital plate in ventral view triangular, longer than wide (Fig. 31A, B). Female subgenital plate in ventral view subsquare. Ovipositor elongated or robust. Valves of the ovipositor narrow, serrate (Fig. 31C, D). Epiproct in females as long as wide near the base, apex pointed. Cerci conical with narrowly rounded apex. Composition and classification. The genus Discotettix is divided into two subgenera: (1) nominotypical Discotettix (type species D. armatus = D. belzebuth) characterized by a long FM projected over the vertex; and (2) Mnesarchus Stål, 1877 stat. resurr. (type species Mnesarchus scabridus = Discotettix scabridus) characterized by a minute FM, not projected over the vertex. The subgenus Discotettix includes six species. One species formerly assigned to Discotettix, that is D. shelfordi, has been transferred to a new genus, Disconius Skejo, Pushkar et Tumbrinck gen. n.

Named after the German biologist Tom Kirschey, our friend and a well-known researcher of the Oriental region, who currently serves as the Head of the International Peatlands and Southeast Asia Programme at NABU (Naturschutzbund Deutschland) headquarters. Distribution and habitat. The species is restricted to NE Borneo, East Sabah. It is found in Danum Valley (and adjacent Kawag Forest Reserve), Tabin Wildlife Reserve, Tawau Hills, Sepilok District, and around the Kinabatangan River Area. The species inhabits the rainforest, where it can be found on the bark of the roots and trunks of trees, among leaf litter, and sometimes on the foliage of seedlings near the ground. According to the photographer, biologist Tom Kirschey, who observed the species in its natural habitat in the lowlands and the mountains of Sepilok, the microhabitat of D. kirscheyi are the roots of the big (old) trees close to pools filled with rain water (Fig. 28). The distribution areas of this species and that of D. belzebuth do not appear to overlap. Diagnosis. The species is similar to D. belzebuth, but can be easily distinguished from the latter by the following set of characters: (1) FM shorter, narrower, and directed more upwards, not covering the entire vertex as in D. belzebuth, which has a large and long digitate FM covering the entire vertex, (2) pronotal projections are much shorter, and not as spiky as in D. belzebuth, but stouter and triangular, (3) femora are stouter and bear stronger teeth than observed in D. belzebuth, and (4) tegmina are smaller, partly covered and not as evident and wide as in D. belzebuth. Description (holotype). General features. Medium-sized, robust species (body length 14.82 mm); pronotum granulated and wrinkled, with one digitate FM on anterior margin and numerous triangular protuberances on dorsal and lateral sides. Almost the whole body (except the eye, labrum, fore and mid tarsi, second and third segments of hind tarsus, and inner side of the hind femur) covered with numerous small tubercles. Macropronotal. Coloration. Body dark brown, almost completely covered by numerous small tubercles. Pronotum, projections, and protuberances dark brown (Figs 23–26, 28, 29). Antenna dark brown, almost black. Proximal segments of the palpi light brown, and distal segments black. The visible part of the tegmen dark brown and without spots. Legs dark brown with lighter rings and patches. Fore and mid femora and tibiae dark brown with numerous small tubercles with lighter apices, fore and mid tarsi black, second segment with a light ring in the middle; 1 st tarsal pads whitish, claws brown. Hind femur dark brown with numerous small tubercles with lighter apices. Hind tibia dark brown with two weak light rings, one in the basal part, and another in the distal third. 1 st tarsus of hind leg pale brown, pads whitish; third segment pale brown with a dark ring in its distal part, claws brown. Tergites, sternites, epiproct, and cerci dark brown. Head. In dorsal and frontal view, vertex 1.95 times as wide as an eye. Fossula elliptic and deep. Lateral ocelli at the level of the lower margin of a compound eye. In frontal view, frontal costa narrow, bifurcated slightly above lateral ocelli into finely granulated facial carinae, forming a narrow scutellum. Scutellum slightly narrower than antennal groove (Fig. 22E). Antennal groove considerably below the lower margin of the compound eye. Antennae 13-segmented, short in appearance compared to D. belzebuth: scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 6 th) elongated, but shorter than in D. belzebuth, and circular in cross-section; central or subapical segments (7 th and 8 th) strongly widened, pennate, 8 th being the widest antennal segment (about 3–4 times as long as wide), but only slightly wider than the 7 th; subapical segments less widened than in the other species of the subgenus Discotettix; apical segment 9 th small and pennate, smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bearing saw-like margins, because of the presence of large basiconic sensilla. When the body and the antennae are covered with algae and moss, the 8 th segment is free of epizoic organisms. Pronotum. Pronotum wrinkled and granulated, covered by numerous small and medium-size tubercles. The posterior process of the pronotum extended beyond the hind knees for less than half of the hind femur length. Disc of the pronotum slightly depressed behind the well-developed shoulder. Pronotum with 5(–7) unpaired projections of variable size on median carina (digitate FM and 4 to 6 medial projections), 3 pairs of FL, up to 7 pairs of more or less distinct mediolateral projections, 3 pairs of lateral projections, and a pair of VL (well seen in profile). Prozona robust, wider than long (because of the short FM). Anterior margin of pronotum projected into a medium-sized digitate FM protuberance directed mainly upwards than slightly forwards, and not covering the whole vertex above. Prozonal and extralateral carinae forming small FL1 and larger FL2, more distinct. FL3 dentiform. Behind the FM medial carina extended along the whole length of pronotum, with 5 unpaired large and small medial projections (well visible in profile). PM triangular and smaller than other medial projections. MM1 is the largest projection; MM2 and MM3 distinct, while MM4 and MM5 small. PML1 and PML2 distinct, tubercle-like. MML1 and MML2 large and triangular; MML3, MML4, and MML5 smaller, decreasing in size caudad. MML4 and MML5 sometimes absent. PL1 and PL2 triangular, tubercle-like. ML sharp and triangular. The apex of the posterior pronotal process in dorsal view shallowly excised. The lower part of the lateral lobe with serrate anterior and posterior margins, elongated as spine-like VL, with saw-like margins, directed outwards (Fig. 22A–C). Wings. The visible part of the tegmen small, oval with a tuberculated surface, visible part 2.57 times as long as wide; the ratio of the maximum width of the mid femur (without teeth)/visible part of tegmina width 1.21. Hind wing not reaching the apex of the posterior pronotal process, ending a few millimeters before the tip. Legs. Femora robust, compressed laterally, surface rough, dorsal, and ventral margins roughly serrate. Fore and mid femora bearing one genicular tooth on knees on each margin, and additionally 3 strong teeth on upper carina and 2–3 on lower margin, almost equal in size; teeth on fore femur equal or larger than on mid femur. Upper and lower margin of hind femur finely serrated, with 2 lappets on each margin, and with numerous small tubercles. Lateral area of hind femur with weak carinae that have up to 3 outgrowths, especially in ventro-external carina. Genicular teeth larger than antegenicular. teeth. Fore femur length/width ratio 4.69. Mid femur length/ width ratio 3.94. Hind femur length/width ratio 3.28. Both sides of the upper margin of the hind tibia finely serrated, with 2–3 outer and 2–3 inner larger teeth (spines). Abdominal apex. Male subgenital plate in ventral view with shallowly excised apex, slightly longer than wide. Female subgenital plate in ventral view with a keel in middle and with a triangular protrusion in the middle of posterior margin. Ovipositor elongated, upper valve 5.0 times as long as wide. The lower valve of ovipositor about 6.0 times as long as wide (maximal width). Cerci stout, with thin apex, hairy. Measurements.

Acridium (Tetrix) belzebuth (nec Serville): De Haan 1843: 166 [reported for Sumatra, misidentification]. Type locality. Sumatra: Padang Panjang (= originally “Padang Pandjang” on the label) [approximate coordinates 0.45S, 100.416667E]. Note on Discotettix selysi identification history. The species was recorded by De Haan (1843) for the first time under the name D. belzebuth, since only D. belzebuth was described at the time (D. selysi being described 44 years later). De Haan’s (1843) drawing of D. belzebuth agrees in morphology with D. selysi. The author, in the description, noted the possession of only one well distinctive anterior pronotal projection. Examination of specimens confirmed that De Haan’s records of D. belzebuth from Sumatra belong to D. selysi and there is no evidence of the presence of D. belzebuth on the island. Material examined.

Photographer Pang Way, det. J. Skejo et J. Tumbrinck (Figs 17, 18) (Facebook). Distribution. This species inhabits the rainforests of southern Peninsular Malaysia and of Sumatra, where it can be found on tree bark and roots (Bolívar 1887; Hancock 1907a; Günther 1938; Mahmood et al. 2007, our data). Taxonomic notes on Discotettix selangori and D. doriae . The description and the measurements of the recently described Discotettix selangori Mahmood, Idris et Salmah, 2007 (type locality Malaysia: Selangor) completely fit that of D. selysi. The new name for the D. selysi population on the Malaysian peninsula does not provide any new information thus we synonymize D. selangori syn. n. with D. selysi. The authors of the former were not aware of D. selysi morphological variability and distribution. In the description (Mahmood et al. 2007), the epitheton was “selangori”, while in the key and under the drawing it was written as “selangorei” (Mahmood et al. 2007). As the first reviewers, according to the ICZN, we pick selangori as the original spelling, while “ selangorei ” is considered a misspelling. We do not agree with Günther’s (1938) synonymy of D. doriae and D. selysi, since a few clear morphological differences can be found (small FM in D. doriae, and swollen antennal segment in D. doriae) thus we regard D. doriae as a separate species with its own traits and distribution (see a paragraph on D. doriae). Diagnosis. The species is morphologically similar to its congeners that do not have strong pronotal projections of the disc, i.e. to D. doriae from Mentawai and D. aruanus from Aru Isl. Discotettix selysi can be distinguished from D. doriae by the following set of characters: (1) D. doriae has FM small and narrow, covering vertex only partially, while in D. selysi FM is large, long, and covering entire vertex); (2) D. doriae is of smaller body size (pronotum length only 16 to 17 mm in females) than D. selysi (pronotum longer than 20 mm in females); (3) D. doriae has shorter and stouter antennae with swollen 6 th, 7 th and 8 th antennal segments, while D. selysi does not have swollen segments and (4) D. selysi has more elongated and slender fore and mid femora, while D. doriae has strong teeth on their ventral and dorsal margins. From D. aruanus sp. n., D. selysi can be distinguished by (I) different shape of the antennae (margins stronger, more saw-like in D. aruanus); (II) different shape of FM (not exceeding the head in D. selysi, exceeding the head in D. aruanus sp. n.); (III) less elevated and less triangular PM and MM1; (IV) legs more robust and toothed in D. selysi than in D. aruanus sp. n., and (V) by larger body size (pronotum length more than 20 mm in females of D. selysi, while less than 17 mm in females of D. aruanus sp. n.). The species is easily distinguished from D. sumatrensis sp. n. from Sumatra, D. belzebuth from Borneo, D. kirscheyi sp. n. from NE Borneo by the lack of strong spines on the pronotal disc and from the Filipino D. scabridus by numerous characters: (I) bifurcation of the frontal costa between the eyes (on the lower margin of the compound eyes in D. scabridus), (II) FM high and developed (present as a small tubercle in D. scabridus), (III) reduced MM, not highly protruded (higher, compressed and saw-like in D. scabridus), (IV) lateral and humeral carinae are granulated (toothed in D. scabridus) and (V) larger body size. From D. belzebuth, D. selysi can be easily separated by (I) less widened antennal segments, (II) FM being the only large medial projection (disc of pronotum with many spine-like MM, ML and MML in D. belzebuth), (III) smoother lateral and humeral carinae (not as equipped and toothed as in D. belzebuth), (IV) hind femora bearing large lappets, (V) fore and mid femora being more armed and stouter, FM shorter and not decurved as in D. belzebuth. From D. sumatrensis sp. n. the species can be distinguished by (I) completely black antennae, (II) FM being the only large medial projection, pronotum without elevated MM, ML and MML and (III) larger body size. Discotettix kirscheyi sp. n. has (1) smaller FM than D. selysi, (II) larger MM1 and MM2, (II) higher MML2s, (III) more robust fore and mid femora with stronger lobes, (IV) less specialized subapical antennal segments, (V) and is smaller in size. Finally, from D. doriae the species can be separated by (I) longer FM, (II) more slender appearance, (III) not swollen subapical antennal segments, and (IV) larger body size. Redescription (Fig. 15). General features. Large-sized and relatively robust species (16–20 mm). Body finely granulated; pronotum slightly rugose, with numerous small tubercles and net-like elevations. The chitinous surfaces are smooth and without tubercles in places, while the rest is strongly granulated. The anterior part of the pronotum bears several strong protuberances, while other projections are reduced (Fig. 15). Macropronotal. Coloration. The general color dark brown, but may be of brighter tints of brown or even dark greenish. Pronotal carinae and projections darker and of a different color than the rest of the body. Median pronotal carina from dark orange to bright red (Figs 16, 17). Antennae completely black or dark brown. Maxillary palpi dark brown. The visible part of the tegmen dark brown without any spots. Legs dark brown except for more or less distinct pale rings on tibiae and tarsi. The body usually covered with algae that give a greenish appearance to the specimens. After preservation in alcohol or drying the greenish color disappears. Head. In dorsal and frontal view, vertex 2.3 times as wide as an eye. Lateral carinae considerably raised and granulated. Fossula deep, but not easily observable because it is covered by large FM of the anterior pronotal margin. Lateral ocelli situated just below the level of the lower margin of a compound eye. Antennal groove significantly below the lower margin of a compound eye. In frontal view, frontal costa bifurcated at the level of lateral ocelli into facial carinae, forming narrow parallel scutellum (Fig. 15E). Antennal groove slightly wider than the frontal costa. Antenna 13-segmented (but in male looks like 12-segmented, because the 13 th segment is very small and not visible under an optical microscope, only under SEM): scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 6 th) elongated and circular in cross-section; central or subapical segments (7 th and 8 th) strongly widened, pennate, 8 th being the widest antennal segment (about 2.7–2.8 times as long as wide); apical segment 9 th elongated and pennate, smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bearing saw-like margins, because of the presence of the large basiconic sensilla. When the body and the antennae are covered with algae and moss, the 8 th segment is always free of epizoic organisms. Pronotum. Pronotum rugose and granulated with numerous small tubercles and net-like elevations, but in some parts smooth and without tubercles (parts of the pronotal disc and some intervals of the median carina of the pronotum). The anterior part of the pronotum bears large FM, and a few medium-sized and small protuberances. The posterior process of the pronotum slender, surpassing hind knees for more than a half-length of the hind femur or less. The disc of the pronotum almost completely flat. A small depression on the disc positioned between the near bases, then the disc becomes slightly elevated again. Caudad, pronotum gradually descending. Disc rich in net-like elevations, more distinct in the places of the interhumeral carinae. The median carina of the pronotum bears unpaired projections of variable size: high and digitate FM, directed upwards and forwards above the head and covering the whole area of the fastigium of the vertex; small triangular PM, a bit larger triangular MM1, small MM2; and completely reduced MM3 and MM4. Prozona subsquare. Prozonal and extralateral carinae in prozona distinct, surpassing anterior margin of pronotum as dentiform small FL1 and larger FL2, FL2. FL3 small, dentiform. Behind the FM medial carina extended along the whole length of pronotum from the anterior margin to the pronotal apex, slightly undulated by the low aforementioned projections. PML1 small, PML2 even smaller. MML1 almost indistinct; MML2 distinct; MML3 very small, while MML4 and MML5 completely indistinct. PL1 and PL2 small. Humeral angle obtuse with pointed apex. ML small, reduced. Pronotum apex narrow, shallowly excised. The lower part of the lateral pronotal lobe with serrate anterior and posterior margins, elongated as spine-like VL, directed strongly outwards and backward (Fig. 15A, B). Wings. The visible part of the tegmen elliptical. Hind wing with scalloped inner margin, a few millimeters shorter than the apex of the pronotal process. In living specimens, the tegmina are covered by photosynthetic microbes (most probably algae and cyanobacteria), so are greenish in appearance. Legs. Fore and mid femora relatively robust, compressed laterally; with dorsal and ventral margins serrated with genicular tooth on the knees and additional 2–3 strongly projected and sharp teeth on each margin. Hind femur with wrinkled margins, one small protuberance situated on the ventral external carina. Genicular tooth large, while antegenicular tooth almost indistinct. Both sides of the dorsal margin of the hind tibia finely serrated, with 3–4 outer and 1–3 inner larger teeth. Abdominal apex. Male subgenital plate in lateral view about two times as long as high.

Disconius shelfordi (Hancock, 1907), comb. n. (Figs 34–36) Vernacular name: Bornean Fallen Pygmy Devil Discotettix shelfordi Hancock, 1907b: 214 [original description, type locality: Borneo]; Kirby 1910: 575 [listed in the catalog]; Günther 1938: 303 [in review]; Yin et al. 1996: 866 [listed in the catalog]; Blackith 1992: 47 [listed in the catalog]; Otte 1997: 32 [listed in the catalog]. Type locality. Malaysia: Borneo: Kuching Note on the syntypes. The species description was based on two syntypes (male and female) labeled as “NW Borneo: Kuching, 22.IX.1899, Collector Dyak (Bornean native), det. J.L. Hancock ” and kept in the Oxford University Museum. As both specimens have been collected at the same locality and date, it is unlikely that they belong to different species. Thus, there is no need for lectotype designation. Material examined. Type material. SYNTYPE 1&female; NW Borneo: Kuching, 22.IX.1899., Collector Dyak, det. J. L.

Photograph by Kinmatsu Lin (@kinmatsu), available at link inaturalist.org/observations/38326084 (Fig. 36). Distribution: Known only from N Borneo; in Sabah from the surroundings of Kuching (type locality) and from the region of the Pajau River; and from Sarawak reported from Marudi (Hancock 1907b; our data). Redescription. (Figs 34, 35) General features. Medium-sized species (body length 14.0– 15.8 mm) (in the original description stated as 17.5–19 mm, but it meant from the tip of the head to the tip of the pronotum ), relatively slender. The entire body finely granulated, covered by numerous small tubercles and with a few larger ones on the margins of the pronotal disc and the lateral lobes; in lateral view the pronotum almost flat, except for the median carina undulated by a few small wart-like and medium-sized semicircular compressed protuberances (Figs 34, 35). Macropronotal form. Coloration. Body color from dark brown and ferruginous brown to brown with an inexpressive grayish tint. Some parts of the body pale colored, previously yellowish: tubercles on the margin of the disc and lateral lobe of pronotum, VL and ML, connections of dark antennal segments, patches on femora, more or less distinct ring in the middle of fore and mid tibiae, two rings (I) in basal and (II) distal third of the hind tibia, distal segments and claws of fore and mid tarsi, and usually yellowish hind tarsus (except for the darker connections of tarsal segments). Living specimens have much more vivid coloration than the museum material. It is visible that the dorsum of the pronotum has an alternation of dark and pale tones (see iNaturalist observation in Material examined). Head. In dorsal and frontal view, vertex about 2.4 times as wide as the eye. Fossula visible, but not deep. Lateral ocelli situated between the compound eyes. The antennal groove situated at the level of the lower margin of the compound eye (in males) or a bit below (in females). In frontal view frontal costa narrow, bifurcates a bit above the lateral ocelli into a slightly divergent facial carinae, slightly concave inside in medium length and forming a narrow hour-glass shaped scutellum (Figs 34C, 35C). Antennal groove considerably wider than scutellum. Antennae 15 segmented, long. Antennomeres are shaped as follows: scapus (1 st antennomere) massive; pedicel (2 nd antennomere) large, basal antennomeres (3 rd to 7 th) elongated, 7 th being extremely elongated; central or subapical segments 8 th to 10 th pennate, 8 th slightly widened, while 9 th, and 10 th significantly widened and flattened; apical segment 11 th small; while apical segments 12 th to 15 th reduced in size, filiform. Pronotum. Pronotum finely granulated, covered by numerous small and few larger tubercles on the margin of the disc and the lateral lobe of the pronotum; almost flat, except for the wrinkled and scalloped median carina with small wart-like and medium-sized, compressed laterally, semicircular protuberances (different in specimens from different geographical populations); posterior process of pronotum very long, surpassing the hind knee for more than a half hind femur length (macropronotal form). Disc of the pronotum almost of the same height in the anterior part, slightly depressed behind the level of the tegmen apex and gradually descending backwards. Morphology of the pronotal projections variable. Pronotum with 5 unpaired projections of variable size on medial carina (FM and 4 medial projections); 2–3 pairs of FL; a pair of VL (better seen in profile); while among the mediolateral and lateral projections only one projection distinct per group. Prozona very short. Anterior margin of pronotum truncated, bearing small and weak triangular FM directed more upwards, then forwards. Prozonal and extralateral carinae low, tuberculated, not forming sharp saw-like or fan-like ridge, with small FL1 and more distinct dentiform. FL3 indistinct. Behind FM medial carina extended along the whole length of the pronotum, low, bearing four more or less distinct medial projections of variable size (well visible in lateral view). PM triangular, equal to or larger than FM and joined with the latter as a continuous two-humped structure in specimens of some populations. MM1, large. MM2 is the largest and the most massive projection, usually compressed laterally as a semicircular triangular protuberance. MM3 relatively large, while MM4 almost indistinct, marked by spot and darker than rest of the pronotal disc surface. Unlike in Discotettix species, Disconius shelfordi comb. n. has only one distinct projection from the mediolateral group, MML2, situated in the place where most Tetrigidae (Tetriginae) species have a posthumeral spot. Similar to the previous projections’ group, only one projection exists from the lateral group of the projections. In the metazona the humero-apical carinae forms a moderately sharp humeral angle, projected outwards as a small ML tubercle of the humeral angle, much larger than other tubercles along the margin of the pronotal disc and the lateral lobe; and behind this point the humero-apical carinae is joining the external lateral carinae. The apex of the posterior pronotal process in the dorsal view shallowly excised. The lower part of the lateral lobe with smooth anterior and posterior margins, without smaller teeth. The lateral lobe elongated as spine-like VL, directed exactly outwards, blunt (Figs 34A, B, 35A, B). Wings. The visible part of the tegmen elongated and oval, distinctly acuminate towards the apex, about 2.75 times as long as wide. Hind wings reach the apex of the pronotal process. Legs. Femora relatively slender, compressed laterally, and finely granulated, with numerous small teeth-like tubercles on the whole surface. Fore and mid femora bearing a hardly noticeable genicular tooth on the knees, and additionally 1–3 small teeth on the dorsal and ventral margin. Hind femur significantly compressed laterally, finely granulated, without any lappets on dorsal and ventral margins, smooth, and not bearing any recognizable outgrowth on the external carinae. Genicular and antegenicular teeth small. Both sides of the dorsal margin of the hind tibia only finely serrated, without any large teeth. Abdominal apex. Male subgenital plate in ventral view about 1.5 times as long as wide, in lateral view about 2 times as long as tall. Ovipositor elongated. Observed variability and differences found among populations, with implications for taxonomy. In the different populations of D. shelfordi comb. n., we have observed that the projections of the pronotum differ in size and shape. For example, among the specimens from the banks of the Pajau river the pronotum projections are much more expressed than in the specimens from Kuching (the type locality of the species). This primarily applies to lower and weaker medial protuberances in the specimens from Kuching. Especially FM and PM are quite small and wart-like, MM is medium size and slightly compressed laterally. In specimens from the Pajau river FM and PM are well expressed, and form a continuous double-hump structure. Other MMs are much more expressed, and more compressed laterally, they have semicircular form, especially the largest MM2. Only the examination of a larger series will allow drawing conclusions about the specific value of the aforementioned traits. Measurements (female syntype and a non-type male).

(FM broken in this specimen) (ZMUH). Type series depository. Zoologisches Museum Hamburg, Germany. Type series depository. Zoologisches Museum Hamburg, Germany (ZMUH). Etymology. Named after the island of Aru. The specific epitheton is a masculine gender adjective in the Nominative case made from the Latinisation of the name Aru (aruanus, aruana, aruanum). Distribution. This species is known to inhabit the Peninsula of Wokam (Wokam Palau), a part of the island of Aru in the southeastern Moluccas. This is the easternmost species of the genus Discotettix. Specific diagnosis. The new species is very similar to Discotettix selysi from the southern Malaysian peninsula and from Sumatra. It shares many traits with D. selysi, but a few subtle differences exist. Due to morphological differences among D. aruanus, D. selysi and D. doriae (Fig. 21) and because of high geographical isolation, D. aruanus sp. n. is proposed as a new species within the genus Discotettix, and not a subspecies of D. selysi. From D. doriae this species is easily separated by (I) the large FM covering the whole vertex and being produced even in front of the head (in D. doriae FM is much smaller) and (II) by much longer antennae without swollen segments. From D. selysi, the new species can separated by the following set of characteristics: (I) FM somewhat larger and in dorsal and lateral views projected before the head (in D. selysi, there are specimens without and with long projected FM); (III) MMLs more elevated than in D. selysi; (IV) PM and MM1 more elevated and more triangular (usually lower and more oblique in D. selysi); (V) VL spine more distinct in D. aruanus sp. n. because the posterior lobe of the lateral pronotal lobe has smaller spikes than in D. selysi (in D. selysi some specimens are similar to D. aruanus); (VI) femora more slender in D. aruanus sp. n. than in D. selysi; and (VII) humeral angles more projected in D. selysi (well visible in frontal view), and infrascapular area thus wider in D. selysi than in D. aruanus sp. n. For a comprehensive comparison with other species of the genus please consult the diagnoses of D. scabridus and D. belzebuth. Description (holotype). General features. Medium-sized, robust species (body length 11.5–13.5 mm in females, pronotum length about 16.5 mm); pronotum granulated and wrinkled, with numerous small tubercles and net-like elevations. The chitinous surfaces are smooth and without tubercles in some places of the dorsum, while the rest is strongly granulated. One large digitate FM on the anterior margin and numerous small triangular protuberances on the dorsal and lateral sides of the pronotum. Almost the entire body (except the eye, labrum, fore and mid tarsi, second and third segments of hind tarsus, and inner side of the hind femur) covered with numerous small tubercles (Figs 19, 20). Only the macropronotal form is known. Coloration. Body dark brown, only some parts of the pronotal net-like elevations orange-red in color. Antenna dark brown, almost black. Proximal segments of the palpi light brown, and distal black. The visible part of the tegmen dark brown and without spots. Legs dark brown with lighter rings and patches. Fore and mid femora and tibiae dark brown with numerous small tubercles with somewhat lighter apices; fore and mid tarsi black, second segment with a light ring in the middle; 1 st tarsal pads whitish, claws brown. Hind femur dark brown with numerous small tubercles with lighter apices. Hind tibia dark brown with two weak light rings, one in the basal part, and another in the distal third. 1 st tarsus of hind leg pale brown, pads whitish; third segment pale brown with a dark ring in its distal part, claws brown. Tergites, sternites, epiproct, and cerci dark brown. Head. In dorsal and frontal view, vertex 1.7 times as wide as an eye. In frontal view, lateral carinae of the vertex considerably raised and granulated. Fossula elliptic and deep, but not easily observable because it is covered by large FM of the anterior pronotal margin. Lateral ocelli situated just below the level of the lower margin of a compound eye. Antennal groove significantly below the lower margin of a compound eye. In frontal view frontal costa bifurcated at the level of lateral ocelli into facial carinae, forming narrow parallel scutellum. Scutellum narrower than the antennal grove and the scapus (Figs 19E, 20E). Antenna elongated 13-segmented: scapus (1 st antennomere) and pedicel (2 nd antennomere) massive; basal segments (3 rd to 6 th) elongated and circular in crosssection; central or subapical segments (7 th and 8 th) strongly widened, pennate, 8 th being the widest antennal segment (about 2.8–3 times as long as wide); apical segment 9 th elongated and pennate, smaller than the subapical and much larger than the rest of the apical segments; apical segments 10 th to 13 th reduced, very small, and borders between them barely visible. Antennomeres 3 rd to 9 th bear strong saw-like margins, likely because of the presence of large basiconic sensilla (Figs 19D, 20D). Pronotum. Pronotum rugose and granulated with numerous small tubercles and net-like elevations, but in some parts smooth and without tubercles (parts of the pronotal disc and some intervals of the median carina of the pronotum). The anterior part of the pronotum bears one large FM, and a few medium-sized and small protuberances. The posterior process of the pronotum slender, surpassing the hind knees for more than a half-length of the hind femur (macropronotal form). The disc of the pronotum is visually flat, but upon a closer inspection, many triangular elevations (projections) may be observed. A depression is visible on the pronotal disc positioned between the bases of the tegmina, then the disc becomes slightly elevated again. Caudad, pronotum gradually descending. The pronotal disc is rich in chitinous net-like elevations, more distinct in the interhumeral region. Medial carina extended along the whole length of the pronotum from the anterior margin to the pronotal apex, slightly undulated by the unpaired projections of variable size: the largest is high and digitiform massive FM, directed upwards and forwards above and before the head and covering the whole area of the fastigium of the vertex; triangular PM, a large triangular MM1, small triangular MM2; small MM3, and almost completely reduced MM4. Prozona subsquare. Prozonal and extralateral carinae in the prozona distinct, surpassing anterior margin of the pronotum as a small dentiform FL1 and large FL2, which is also well visible in frontal view. FL3 small and dentiform. PML1 and PML2 small. MML1 and MML2 distinct; MML3 very small; MML4 and MML5 indistinct. PL1 and PL2 small. Humeral angle obtuse with a pointed apex. ML small, reduced. Pronotum apex narrow, shallowly excised in the middle. The lower part of the lateral pronotal lobe bearing small teeth on the anterior and the posterior margins, with the middle region elongated as a large spine-like VL, directed mostly outwards and slightly backward (Figs 19A–C, 20A–C). Wings. Tegmina partly covered, not as easily discernible as in D. doriae and D. selysi. The visible part of the tegmen elliptical. Hind wing not reaching the pronotal tip for a few millimeters. Legs. Fore and mid femora elongated, but with robust armature on the dorsal and ventral margins. Fore and mid femora compressed laterally; with dorsal and ventral margins serrated with genicular tooth on the knees and additional 2–3 strongly projected and sharp teeth on each margin. Hind femur bearing small lappets on dorsal and ventral margins and one small protuberance on the ventral external carina. Genicular tooth large, while antegenicular tooth very small. Both sides of the dorsal margin of the hind tibia finely serrated, with 3–4 outer and 1–3 inner larger teeth. Abdominal apex. Female subgenital plate in ventral view bearing a longitudinal keel in the middle and has a triangular protrusion in the middle of the posterior margin. Ovipositor, in ventral view, seems to be elongated, but dorsal valvae are not visible because of the decurvation of the pronotal tip, which is directed downward. Ventral valvae are elongated, but for example in D. selysi the dorsal are more robust, which can be expected in D. aruanus sp. n. as well.

Subgenus Mnesarchus Stål, 1877, nom. resurr. Mnesarchus Stål, 1877: 55; synonymized with Discotettix by Bolívar (1887). Mnesarchus (as subgenus of Discotettix): Kevan 1966: 380. Discotettix (partim): Bolívar 1887: 306; Kirby 1910: 2 [listed in the catalog]; Blackith 1992: 46 [listed in the catalog]; Yin et al. 1996: 866 [listed in the catalog], Otte 1997: 32 [listed in the catalog]. Type species: Mnesarchus scabridus Stål, 1877, by original monotypy. Taxonomic notes. The genus Mnesarchus have been synonymized with Discotettix by Bolívar (1887). Kevan (1966) recognized it as distinct subgenus but later Mnesarchus has been considered a synonym of Discotettix again (Blackith, 1992; Yin et al., 1996; Otte, 1997). The type species is morphologically very different from other Discotettix members and is thus assigned to its own subgenus, Mnesarchus. It can be easily separated from other species of the genus by the set of the following characters: (I) frontal costa bifurcates at the lower margin of the compound eyes (bifurcation is in the lower third of the compound eyes in D. aruanus sp. n., D. belzebuth, D. doriae, D. kirscheyi sp. n., D. selysi, and D. sumatrensis sp. n.), (II) FM present as a low tubercle (developed and elevated in D. aruanus sp. n., D. belzebuth, D. doriae, D. kirscheyi sp. n., D. selysi, and D. sumatrensis sp. n.), (III) MM laterally compressed and elevated (spine-like in D. belzebuth, triangular protrusions in D. sumatrensis sp. n., D. kirscheyi sp. n., while very low in D. aruanus sp. n., D. doriae and D. selysi), (IV) MML low and triangular, compressed elevations (spine-like in D. belzebuth, triangular protrusions in D. sumatrensis sp. n., similarly formed in D. selysi), (V) interscapular area triangular, with large concavity (similarly to D. selysi, and D. sumatrensis sp. n., almost parallel in D. belzebuth), (VI) lateral and humeral carinae strongly toothed (similar to D. belzebuth, granulated in D. selysi, and D. sumatrensis sp. n.), (VII) weak ML (almost absent in D. scabridus, while well visible in other species), (VIII) VL complex, with a few spines (in other species usually with one main spine, and a saw-like margin) and (IX) tegmen more elongated (TL/TW > 5) than in the other species of the genus (TL/TW Composition. The type species of Mnesarchus is the only species presently assigned to this subgenus., Published as part of Skejo, Josip, Pushkar, Taras I., Kasalo, Niko, Pavlović, Marko, Deranja, Maks, Adžić, Karmela, Tan, Ming Kai, Rebrina, Fran, Muhammad, Amira Aqilah, Abdullah, Nurul Ashikin, Japir, Razy, Chung, Arthur Y.

Etymology. The new species is named sumatrensis (adjective masculine, third, vocal declension) after the type locality, Sumatra Island. Distribution and habitat. The species is currently known only from Mt. Kerinci, Sumatra, the highest vulcano in Indonesia and the Sumatra’s highest peak (above 1500 m). The mountain is surrounded by lush forest. It is an isolated mountain, so there is a chance of D. sumatrensis being a local endemic. Distribution is shown in Fig. 3. Specific diagnosis. The species is morphologically similar to D. kirscheyi sp. n. from Borneo and can be easily distinguished from other species. From D. scabridus the species differs by: (I) frontal costa bifurcates between the eyes, (II) FM well developed, (III) MM triangular and elevated, (IV) MML triangular and elevated, (V) lateral and humeral carinae granulated. The species can be distinguished from D. belzebuth by the following characters: (I) smaller body size, (II) peculiar coloration of antennae with lighter colored segments, (III) antenna with 7 th segment being the widest (not the 8 th as in most of the other species), (IV), pronotum with smaller triangular projections, except the digitate FM, (V) hind femur with large lappets (smaller in D. belzebuth), and (VI) ovipositor generally slenderer than in D. belzebuth. The species differs from D. selysi by (I) peculiar coloration of antennae with lighter colored segments, (II) widened antennal segments narrower than in D. selysi, (III) pronotal disc with numerous triangular protuberances and (IV) large lappets of hind femur (medium sized in D. selysi). The species is similar to D. kirscheyi sp. n. but can be easily distinguished from the mentioned by (I) longer FM, (II) stronger pronotal projections, (III) specialized and colorful antennal segments and (VI) smaller body size. Holotype description. (Figs 30, 31) General features. Medium sized, robust species (body length 11.7–13.5 mm); pronotum granulated and wrinkled, with one digitate FM on anterior margin and numerous triangular protuberances on dorsal and lateral sides.Almost the entire body (except eye, labrum, fore and mid tarsi, second and third segments of hind tarsus, inner side of the hind femur) covered with numerous small tubercles (Figs 31, 32). Macropronotal. Coloration. Body dark brown, almost completely covered by numerous small tubercles with lighter apices.

Subfamily Scelimeninae Bolívar, 1887 Discotettiginae: Steinmann 1970, Storozhenko 2013, Tumbrinck 2014, syn. n. Discotettigiae: Hancock 1907a, Hancock 1907b, Willemse 1930, Günther 1938, syn. n. Discotettinae: Otte 1997, Mahmood et al. 2007, syn. n. Discotettigidae: Liang et Zheng 1998, Zheng 2005, Deng et al. 2007, syn. n. Notes. Herewith proposed definition of Scelimeninae is different from recent literature. Bolívar (1887) created the section (now subfamily) to include all Tetrigidae species with outwardly directed spines. Günther (1938) defined two groups within Scelimeninae —1) “Scelimenae verae” to include what are now Scelimeninae, i.e., the genera related to the type genus Scelimena, and 2) “Scelimenae spuriae” to include genera with lateral spines that are not closely related to the genus Scelimena. These “Scelimenae spuriae” are what we know today as tribes Criotettigini and Thoradontini. Kevan (1966) was the one to create the tribes Scelimenini, Thoradontini, Discotettigini, and Criotettigini. Thoradontini and Criotettigini were already then (Kevan 1966) defined as tribes for the taxa from the heterogeneous genera of section “Scelimenae spuriae”. Ad&zcaron;i&cacute; et al. (2020) confirmed the existence of two related tribes, Thoradontini and Criotettigini, which do not belong to Scelimeninae. The current definition of Discotettigini is very different from the Kevan’s (1966) definition, which was unfortunately based on a very partial list of genera by Günther (1955), so it may be regarded as the start of a highly chaotic taxonomy in Otte (1997) and later in Orthoptera Species File (Cigliano et al. 2022). Criotettigini and Thoradontini require revision and might be synonymous. Liang & Zheng (1998) and consequent Chinese authors ignored the taxonomic treatment by Kevan (1966), which we regard as useful, as far as the genera related to the type genus are included in the tribe. Muhammad et al. (2018) provided the most recent treatment for Scelimeninae: Scelimenini, which we follow in this paper. Composition and distribution (sensu Günther 1938, with additions from Muhammad et al. 2018 ). The subfamily currently counts 180 species within 23 genera. The tribe Scelimenini includes amphibious Asian and Papuan taxa with flat pronotum (genera Amphibotettix Hancock, 1906, Euscelimena Günther, 1938, Indoscelimena Günther, 1938, Paramphibotettix Günther, 1938, Platygavialidium Günther, 1938, Scelimena Serville, 1838, Tagaloscelimena Günther, 1938, and Tefrinda Bolívar, 1906), while the tribe Discotettigini stat. resurr. gathers Asian and Papuan corticolous taxa with undulated pronotum (genera Austrohancockia Günther, 1938, Bidentatettix Zheng, 1992, Disconius Skejo, Pushkar et Tumbrinck, gen. n. Discotettix Costa, 1864, Eufalconius Günther, 1938, Gavialidium Saussure, 1862, Gibbotettix Zheng, 1992, Kraengia Bolívar, 1909, Paragavialidium Zheng, 1994, Tegotettix Hancock, 1913). Genera Zhengitettix Liang, 1994, Hebarditettix Günther, 1938, Falconius Bolívar, 1898, and Dengonius Ad&zcaron;i&cacute;, Deranja, Franjevi&cacute; et Skejo, 2020 are of uncertain position within Scelimeninae, while Arulenus Stål, 1877 and Hirrius Bolívar, 1887 do not belong to this subfamily and should be removed from it, thus remaining without subfamily assignment for now., Published as part of Skejo, Josip, Pushkar, Taras I., Kasalo, Niko, Pavlović, Marko, Deranja, Maks, Adžić, Karmela, Tan, Ming Kai, Rebrina, Fran, Muhammad, Amira Aqilah, Abdullah, Nurul Ashikin, Japir, Razy, Chung, Arthur Y.

Genus Disconius Skejo, Pushkar et Tumbrinck gen. n. Type species: Discotettix shelfordi Hancock, 1907 (= Disconius shelfordi comb. n.). Justification for the establishment of the new genus. Head and pronotum morphology of Disconius shelfordi comb. n. differs too widely from other Discotettix species for it to be regarded as a member of the latter genus, so a new monotypic genus is established for this species, Disconius Skejo, Pushkar et Tumbrinck gen. n. Fastigial horns are lower, while the bifurcation of the frontal costa, lateral ocelli and antennal grooves have a much higher position than in any Discotettix species. Unlike FM and high pronotal projections in Discotettix, Disconius gen. n. lacks elevated FM (present as a small tubercle on the anterior pronotal margin); FL1 and FL3 are not strongly projected forwards as in Discotettix, and the strongest projections are ML of the shoulders area (similar to Tegotettix). The new genus is assigned to the subfamily Scelimeninae and to the tribe Discotettigini stat. resurr. on the basis of the width of the vertex (wide) and the weak elevation of the lateral carinae of the vertex; the typical arrangement of the pronotal projections (FM, MM, MML, ML); armed femora; and not widened hind tibiae and tarsi. The new genus is similar and likely related to the genera Tegotettix and Discotettx, but also superficially resembles Falconius. From Tegotettix and Falconius it can be easily distinguished by widened antennal segments, while from Discotettix, to which it was formerly assigned, it can be distinguished by a number of characteristics stated above. Molecular and comprehensive morphometric comparison of Disconius shelfordi comb. n. with large series of Discotettix, Tegotettix, and Falconius specimens is needed in the future, to elucidate the evolution of this curious taxon. Composition and distribution. A monotypic genus, including only Disconius shelfordi (Hancock, 1907) comb. n., known only from northern Borneo. Etymology. Because of the former taxonomic placement within Discotettix, and because of the superficial similarity to certain members of the genus Falconius due to its slender appearance and the shape of the pronotal projections, the names of two genera were combined into Disconius, meaning that this is both Discotettix -like and Falconius -like genus. Differential diagnosis. For the comparison with Discotettix, from which Disconius gen. n. has been removed, see the justification above, as well as the diagnosis of the genus Discotettix. From the genus Tegotettix (including T. armatus and T. bufocrocodil) the genus can be separated by head morphology — lateral ocelli positioned higher, frontal costa short before the bifurcation, vertex not bearing high horns, antennae with widened subapical antennal segments, and tibiae not armed. From the genus Falconius, Disconius gen. n. can be separated by the arrangement of the pronotal projections, the lack of flattened hind tarsi, and by widened apical segments of the antennae. Description. Head. Frontal costa bifurcation between the compound eyes; scutellum narrower than scapus; upper margin of the antennal groove above the lower margins of the compound eye; lateral (paired) ocelli between the compound eyes; eyes protruded above the vertex Antennae 15-segmented (1 st scapus; 2 nd pedicel; basal 3 rd –7 th elongated; central or subapical 8 th weakly compressed, 9 th elongated and strongly compressed; 10 th compressed; apical segment 11 th small; apical 12 th –15 th reduced, smooth and cylindrical). Vertex wider than a compound eye. Lateral carinae of the vertex in frontal view weakly elevated, medial carina of the vertex visible, anterior margin of the vertex slightly indrawn. Pronotum. Body robust, the ratio of the humeral angles’ width to the prozonal width more than 3.5. Anterior margin of the pronotum truncated or slightly excised, without strongly elevated FM; prozonal carinae distinct and parallel; extralateral carinae strong, with FL2 as a small elevation; FL3 weak; medial carina continuous along all the pronotum, tuberculated; MM high compressed elevations; PMLs and MMLs distinct; MML2 well developed as a high tubercle; ML triangular protrusion with a tubercle on its tip; interhumeral carinae distinct; interscapular area distinct and with parallel margins; lateral area as wide as the interscapular area; humero-apical, humeral, and lateral carinae with triangular or spine-like projections; VL protruded as a weak spine; paranota triangular; dorsum of the pronotum without Discotettix — characteristic net-like elevations, but still rough. Legs. Fore and mid femora carinated above, armed with a few small teeth on the dorsal and ventral margins; the dorsal margin of hind femora strongly armed; ventral margin with undulated carinae; the external surface of the hind femora with recognizable transverse ridges; hind tibia finely, densely serrate with numerous small teeth, but without large teeth; distal part of the hind tibia slightly widened, proximal tarsal segment slightly widened; first and the third tarsal segments of the hind legs almost equal in length; pulvilli typical for Scelimenini —first two angular and the third obtuse., Published as part of Skejo, Josip, Pushkar, Taras I., Kasalo, Niko, Pavlović, Marko, Deranja, Maks, Adžić, Karmela, Tan, Ming Kai, Rebrina, Fran, Muhammad, Amira Aqilah, Abdullah, Nurul Ashikin, Japir, Razy, Chung, Arthur Y.

M.K. Tan; KB.16.15 (ZRC) Remarks. When Ectatoderus nigrofasciatus Tan et al., 2021 was first described, the basal part of the male genitalia of the holotype was not examined (Tan et al., 2021: Fig. 7). The apical part of the male genitalia, previously thought to be the complete genitalia, was considered to resemble that of Ectatoderus argentatus Ingrisch, 2006 from Thailand. However, after examining more specimens collected from Brunei Darussalam, it was found that the basal half of the male genitalia of E. nigrofasciatus has in fact the medial valve curved to a spiral. This character is more similar to that in Ectatoderus angusticollis Chopard, 1969 from Singapore (Fig. 3). Below, the diagnosis is revised accordingly. Revised diagnosis. The species is characterised by the scapus being dorsally black, but ventrally and laterally brown, and the antennae being entirely black basally; the head has a distinct black band behind eyes; and the male phallic complex is very large and forming a spiral. The new species is most similar and closest in distribution to E. angusticollis. In both species, the pronotum is more strongly widening toward apex, and the TIs and TIIs are provided with black dorsal stripes. The male phallic complex is very similar to that of E. angusticollis, including the spiral-shaped medial valve and the shape of the ventro-external sclerite. The species differs from E. angusticollis by the male phallic complex being exceptionally larger despite of having very similar body size (Fig. 3); the scapus and antennae being black (instead of testaceous); and the head being provided with distinct black and white bands behind eyes. The new species is also similar to E. argentatus having the pronotum strongly widening apically and the frons dark; it differs by the scapus and basal antennal segments being darkened instead of yellowish brown, and by the male phallic complex forming a spiral at base instead of being merely curved.

EAST MALAYSIA, Sabah State, Sepilok Calling song (1 &male;, in captivity, 26.4°C) (Fig. 2). The calling song generally consists of a sequence of echemes which can be highly variable in duration (8–26 s). The echeme sequence typically begins with the echemes more erratic in terms of number of syllables, syllable durations and intervals. Each echeme is made up of 4–10 syllables (= pulses), and has an average duration of 140.9±65.3 ms (78.0–249.1 ms). Consecutive echemes have an average interval of 371.6±86.3 ms (285.6–474.3 ms). The average syllable duration is 14.1±1.5 ms (11.9–15.6 ms) and the average interval between consecutive syllables is 7.2±1.6 ms (5.4–9.7 ms). The dominant frequency is 8.34 kHz. Compared to the continuous trill of Cycloptiloides timah Ingrisch, 2006 from Singapore (see Tan et al., under review), the calling song of C. bimaculatus also differs by a distinctly shorter syllable duration (14.1 ms in C. bimaculatus vs. 25.7 ms in C. timah) and by the intervals between consecutive syllables (7.2 ms vs. 104.5 ms). The dominant frequency is also distinctly lower (8.3 kHz vs. 9.1 kHz). It should be noted that the average temperature of the recordings for the two species are different (26.5°C in C. bimaculatus vs. 30.5°C in C. timah), which may have contributed partly to the differences in the call parameters between the two species., Published as part of Tan, Ming Kai, Japir, Razy, Chung, Arthur Y.

Ornebius lupus Tan, sp. nov. (Figs 1C, 1D, 6, 7) Ornebius sp. — Tan et al. under review [calling songs from Singapore] Specimens examined. Holotype: SINGAPORE • 1&male;; Pasir Ris mangrove boardwalk; N1.37805, E103.95147; 19 March 2022, night time; on foliage of mangrove tree; coll. M.K. Tan; ZRC Paratypes: SINGAPORE • 1&male;; Pasir Ris mangrove boardwalk; N1.37805, E103.95147; 2 May 2022, night time; on foliage of mangrove tree; coll. M.K. Tan; MNHN-EO-ENSIF11343 Diagnosis. The new species has genitalia which appear most similar to those in the species group Ornebius (rufonigrus) Ingrisch, 1987, but differs by the dark-grey colouration; the maxillary palps being not so elongated (more similar to Ornebius alvarezi Tan, Ingrisch, Baroga-Barbecho & Yap, 2019 from the Philippines; elongated oblong in Ornebius dumoga Ingrisch, 2006 from Sulawesi and in Ornebius consternus Ingrisch, 2006 from Sulawesi), the FW colouration darker (orange in O. dumoga and in Ornebius rufonigrus Ingrisch, 1987 from Indochina and Malay Peninsula) and less covered by the pronotum (compared to O. consternus). The male genitalia of this new species differ from congeners from the species group by the internal sclerites at base being smaller instead of expanded. We also compared the new species with other species currently not placed in any species group (i.e., with unknown male genitalia). Our species resembles species with wholly dark/ black or smoky FWs, such as Ornebius obscuripennis (Chopard, 1930) from Sarawak and Ornebius fuscipennis (Chopard, 1929) from Sumatra (including Padang, Pulau Sipura, Pulau Telo and Batu Islands). The new species differs from O. obscuripennis by the pronotal lateral lobe and lateral parts of the head being dark-grey (i.e., unicolorous with dorsal parts) instead of forming a yellow lateral band. It also differs from O. fuscipennis by much smaller body size (BL 8.4 vs. 10.5 mm; PL 2.8 vs. 4.5 mm; TL 2.5 vs. 2 mm; FIIIL 4.4 vs. 7 mm); by the FW more uniformly coloured instead of smoky with posterior margin blackish; by the apical segment of the maxillary palps longer than subapical and third; by the pronotal disc not covered with yellow-brown scales; and by the legs that are not unicolourous yellowish. Lastly, the new species also differs from a syntopic species, Ornebius tampines Tan & Robillard, 2012 by the overall body and FW colouration, the body shape is more typical of Ornebius, instead of slenderly built, the shape of the male genitalia and by the calling songs (see Tan et al., under review). It is also somewhat similar to a sympatric species, O. pullus by the wholly black FWs, but differs by the lack of white margins along the lateral lobe and the posterior margin of the dorsal disc of the pronotum, by the shape of male genitalia and by the calling songs (see Tan et al., under review) Etymology. The species name refers to the dark-grey colouration, resembling the grey-wolf, Canis lupus. Description. Small species; habitus of male as shown in Fig 1C, 1D. Dorsum of head flattened, covered with dark-grey scales (Figs. 6A). Frontal rostrum 2.0 times wider than scapus (Fig. 6A). Scapus dark-grey (Fig 6A); basal antennal segments black, thereafter brown with some segments black (Figs 6B, 6C). Frons and mouthparts of dark colour (Fig. 6B). Maxillary palps pale grey; with apical (= fifth) segment longer than subapical (= fourth) segment, third segment of subequal length as subapical segment; apical segment pyriform (Fig. 6C). Lateral parts of head, including genae, of dark colour, without bands (Fig. 6C). Pronotal disc brown and wholly covered with dark-grey scales, about 1.3 times longer than wide, with anterior margin narrow and straight; lateral margin widening slightly posteriorly; covering only base of mirror of FW; posterior margin convex (Fig. 6D). Lateral lobe of pronotum also wholly covered with dark-grey scales (Figs 1D, 6C). TI with internal tympanum small and oval; without external tympanum. FIII 1.4–1.5 times longer than TIII; TIII 2.6 times longer than MTaIII. Femora generally pale, covered with marmoration of dark-grey scales except in basal parts. Tibiae and tarsi generally grey. Abdominal tergites covered with dark-grey scales; sternites pale. Abdominal apex darkened. Cercus covered with grey scales. Male. FW mostly infumated black, dorsal field darkest at posterior margin (Fig. 6D); lateral field likewise in some areas with infumated white veins (Fig. 6E). Supra-anal plate with last abdominal tergite and epiproct distinctly separated by a transverse suture. Last abdominal tergite transverse, posterior margin abruptly indented in middle; with oval pale spot in middle (not obvious in dry-pinned specimen) (Fig. 6F vs. 6G); posterior margin on either side of the indentation with two patches of short and strong setae. Supra-anal plate less transverse than last abdominal tergite, black coloured, apex subtruncate (Figs 6F, 6G). Subgenital plate black (Fig. 6H). Paraproct process black, elongate, cylindrical and tapering into a subacute apex (Fig. 6H). Genitalia as in Fig. 7. Central lobe of phallus with lateral valves (lv) elongate, apical area curved slightly ventrad in lateral view; tapering into obtuse apex, in apical area with inner margin curved in dorsal view; both sides together almost forming a dorsally and ventrally open tube.

Ornebius pullus Ingrisch, 2006 (Figs 1B, 4, 5) Ornebius pullus Ingrisch, 2006: 157 Ornebius pullus — He et al. 2021: 88 [assigning to species group Ornebius (flori) Ingrisch, 1998]; Tan et al. 2021: 416 [notes on new locality and variations with Singapore specimens]; Tan et al. under review [calling songs from Singapore] Ornebius cf. pullus — Tan 2012: 34; Tan & Ingrisch 2013: 25; Tan 2017: 55; Tan 2019: 335 Specimens examined. EAST MALAYSIA • 1&male;; Sabah State, Tabin Wildlife Reserve; N5.19496, E118.50326, 117.1± 10.3 m.a.s.l.; 15 May 2022, 22h17; on the branch of a small tree; coll. M.K. Tan, T. Robillard & R. Japir; SBH.22.95 (FRC) Remarks. The specimen collected from Sabah exhibits some differences with O. pullus collected from Belait (Brunei Darussalam) and Singapore: legs with more whitish marmoration, supra-anal plate whitish when alive. However, we could not identify clear-cut differences in the genitalia, including both the sclerotized median valve and the membranous lateral valves between the specimen from Sabah and those from Brunei Darussalam (Fig. 5). As Tan et al. (2021) have also suggested that there might be a polymorphic species and that more evidence was needed (e.g., DNA or acoustics) to better understand the species boundaries. At the moment, the external morphology and genitalia morphology are not congruent between specimens from Brunei Darussalam, Singapore and Sabah; we also do not have acoustic data for the Brunei population; and no molecular data are available. Furthermore, the specimen from Sabah also shares some similarities (but also with clear differences) in the external morphology of Ornebius minusculus (Chopard, 1929) from Sipura Island (Sumatra) (http://coldb.mnhn.fr/ catalognumber/mnhn/eo/ensif4531), although the genitalia for this species has not been examined. As such, without more specimens from Sabah to examine variations, we refrained from describing it as a new species, tentatively identified it as O. pullus and preferred to revise its taxonomy when the chance arises. Distribution. Brunei Darussalam (Belait and Brunei-Muara Districts), East Malaysia (Sabah State) [new locality record], Singapore. Type locality. BRUNEI DARUSSALAM, Brunei-Muara District, near bridge over river Sungai Lubang Barus on road coming from Tutong. Calling song (1 &male;, in captivity, 31.5°C) (Fig. 4). The calling song generally consists of a sequence of syllables (= pulses), which can be highly variable in duration (2–14 s or 4–25 syllables). The average syllable duration is 37.5±5.0 ms (31.0–46.0 ms) and the average interval between consecutive syllables is 501.2±20.4 ms (469.3–538.4 ms). The dominant frequency is 7.97±0.13 kHz (7.78–8.16 kHz). Compared to the calling song of Ornebius pullus from Singapore (see Tan et al., under review), the calling song of this specimen from Sabah has a similar call structure (i.e., the calls of both species are made up of a sequence of syllables). The biggest difference is in the interval between consecutive syllables being distinctly longer (501.2 ms vs. 400.0 ms) than that from Singapore. The syllable is only marginally longer in duration on average (37.5 ms vs. 32.4 ms) and the dominant frequency is not different (8.0 kHz vs. 8.1 kHz)., Published as part of Tan, Ming Kai, Japir, Razy, Chung, Arthur Y.

Chopard (1969) redescribed the species Aphonoides cinereus (Haan, 1844) and suggested that this species is widely distributed in the Oriental Region. Gorochov (2007 [2006]) instead, postulated that the syntypes may belong to different species, but the genitalia could not be examined for these specimens. The genitalia and the description of Aphonoides ? cinereus sensu Gorochov (2007 [2006]) were based on specimens from Penang in Malay Peninsula and Tawai in Borneo. The specimen collected from Singapore shares genitalic characters of the specimens from Borneo and Malay Peninsula. It has the minutely and faintly indented apex of the posterolateral epiphallic lobe and the lateral view of genitalia most similar to Aphonoides ? cinereus from Borneo; the ectoparamere most similar to Aphonoides ? cinereus from Penang.

Cercoteratura repens sp. nov. (Figs 1–3) Material examined. Holotype: EAST MALAYSIA • 1&male;; Sabah State, Sabah State, Tabin Wildlife Reserve; flying among grasses near the resort check-in area; 17 May 2022, 10h; coll. M.K. Tan; SBH.22.120 (FRC) Diagnosis. This new species differs from the other congeners by the posterior end of the 10 th abdominal tergite being deeply notched in the middle and with spatulate posterior lateral lobes; the posterior end of the epiproct having a large truncated medial lobe which is narrowly emarginated in the middle; the lamellate cercus with a small rectangular lamellate lobe in the middle along the inner margin; the apex of the cercus acute, pointing anteriorly; the epiphallus consisting of a medial large plate (with two dorso-lateral and two ventro-lateral lobes) and two smaller lateral plates. The new species is most similar to Cercoteratura abbreviata (Karny, 1924) from Sumatra by the uniform yellow (light green when alive) colouration, shapes of the epiproct and cercus; but differs by the cercus stouter (slenderer and longer in C. abbreviata) and more angularly upcurved (more broadly upcurved in C. abbreviata) at the apical half, and by the cercus not emarginated at the apex. The new species also has similar uniform yellow (light green when alive) colouration as Cercoteratura modesta Gorochov, 2019 from Sumatra but differs by the shapes of the male epiproct and cercus. From a Bornean congener, the new species differs from Cercoteratura mirabilis (Tan & Wahab, 2018) from Brunei Darussalam by the colouration (without dark markings) and the shapes of epiproct and cercus. Remarks. The new species should be compared with Xiphidiopsis (Xiphidiopsis) phyllocercus Karny, 1907 from Borneo, but its original description is very brief and the types could not be located. This species is characterised by its compressed leaf-shaped cercus, perhaps not too different from the new species, but nothing else is known about the abdominal apex and phallic complex. Etymology. The species name refers to the ventrad spreading of the strong, dark sclerotization on the medial plate of the epiphallus, characteristics of the species. In Latin, ‘repens’ means ‘spreading’ and ‘creeping’. Description. Habitus typical of Meconematini (Fig. 1A) Generally green when alive. Head pale green to green, with tint of yellow brown on antennal scapus and pedicel. Eyes globular (Fig. 1). Frontal rostrum conical, stout, with rounded apex of upper tubercle having median sulcus feebly present (Fig. 1B). Antennal segments with apical parts black. Mouthparts generally light coloured. Apical segment of maxillary palpi long and slender, faintly widened apically and blackish at the apex; fourth slightly shorter than third segment in length (Fig. 1A). Pronotum covering most part of tegminal mirror (Fig. 1B), green with margin yellow brown. Pronotal disc roundly turned into lateral lobes, transverse sulcus distinct but very shallow; dorsal edge of pronotum almost straight in profile; anterior margin of pronotal disc faintly convex, posterior margin angularly rounded (Fig. 1); Ventral margin of pronotal lateral lobe short and rounded. Thoracic auditory spiracle (= thoracic foramen) large and bean-shaped; not covered by pronotal lateral lobe (Fig. 1A). Tegmen rather narrow, with narrowly rounded apex, reaching basal part of hind tibiae; with a few irregular black spots after basal third. Hind wing slightly surpassing tegminal apices. Legs generally pale green; tarsi and apex of tibiae black. Femora without spine; fore and middle tibiae each with 4 outer and 4 inner subapical spines; inner and outer knees of hind femora with rounded lobes each with a small apical spine; hind tibiae ventrally and dorsally with numerous outer and inner spines as well as 2 ventral and 1 dorsal apical spurs on each side. Spines on legs mostly black. Knees not darkened. Male. Abdominal apex as in Fig. 2. 10 th abdominal tergite and epiproct somewhat fused together. 10 th abdominal tergite with posterior end deeply notched in the middle, with posterior lateral lobe produced between the notch; posterior lateral lobe slender, dorso-ventrally compressed with spatulate apex. Epiproct with posterior end a large medial lobe; this lobe surpasses posterior lateral lobes of 10 th abdominal tergite, narrowly emarginated in the middle, with apex truncated. Cercus with basal third dorso-ventrally flattened but rather narrow, angularly incurved. Cercus in the middle with a small rectangular lamellate lobe along inner margin, with apex truncated. Posterior of the inner lamellate lobe, cercus lamellate and widened, strongly upcurved and then incurved. Apex of cercus acute, pointing anteriorly. Subgenital plate broad at basal half; lateral margins narrow and converge considerably at apical half; apical margin narrow and truncated. Styli inserted at the apical margin of subgenital plate short and slender. Phallic complex as in Fig. 3. consists of membranous ventral lobe with apex narrow and little emarginated. Epiphallus sclerotized, consisting of a medial large plate and two smaller lateral plates. Medial plate with two dorso-lateral lobes and two ventro-lateral lobes; dorso-lateral lobes pointing antero-laterally with subacute apices; ventro-lateral lobes broader and stouter, lamellate, pointing ventrad with truncated apices. Medial plate also more strongly sclerotized in the middle; this sclerotization forked into the two ventro-lateral lobes, each broadly forked again. Female. Unknown. Measurements (1&male;, in mm).

M.K. Tan, T. Robillard & R. Japir; SBH.22.24 (FRC) Taxonomic remarks. The male specimen resembles Neophisis (Indophisis) longipennis as described by Jin (1992), particularly by the key diagnostic characters: the cephalic lobe of the epiphallus with lateral margins denticulate, parallel and narrowing at the apical third into a subacute apex; the ventral phallomere with divided apices; the cercus flattened and abruptly bent in the middle and with a small node basally; the 10 th abdominal tergite with the two lateral lobes narrowly separated from the middle truncated part; the posterior end of the subgenital plate angularly emarginated in the middle; the general shape of paraproct; and the mirror area of the FW with a relatively small oblique dark patch. Distribution. Borneo: Kalimantan, Sabah (Mount Silam) [new locality record] Type locality. INDONESIA, Kalimantan “Indonesia: Midden [= Central] Borneo” Calling song (1&male;, 21.6°C, in the laboratory). The calling song consists of isolated echemes. Each echeme, which has an average duration of 90.1±5.0 ms (82.1–96.6 ms), is made up of two closely-spaced syllables. Each syllable begins with a pulse, followed by a short interval and then ends with 10–12 rapid-decay pulses. The first syllable [52.0±3.5 ms (44.5–53.4 ms)] is typically longer in duration than the second syllable [35.4±3.6 ms (31.5– 41.3 ms)]. For the first syllable, the initial pulse has a duration of 16.3±2.8 ms (10.7–18.7 ms), followed by an interval with a duration of 4.8±0.7 ms (4.0–5.8 ms). The final part of the syllable, made up of the rapid-decay pulses, has a duration of 30.4±0.9 ms (28.9–31.0 ms). For the second syllable, the initial pulse has a shorter duration of 8.8±1.1 ms (7.1–10.0 ms), followed by an interval with a shorter duration of 2.0±0.4 ms (1.5–2.7 ms). The final part of the second syllable, also made up of the rapid-decay pulses, has a duration of 24.5±2.9 ms (21.0–29.7 ms). The number of rapid-decay pulses in the first syllable is always equal or more than that in the second syllable. The last rapiddecay pulse [2.7±0.2 ms (2.5–2.8 ms)] has a distinctly longer duration than the other rapid-decay pulses [0.5±0.1 ms (0.4–0.7 ms)]. The average interval between the rapid-decay pulses is 1.6±0.5 ms (1.1–2.6 ms). The call spectrum has a peak frequency of 36.6±0.2 kHz (36.3–366.8 kHz), and the two parts of each syllable have very similar peak frequency. Likewise, the spectral entropy is 0.73±0.01 (0.71–0.75), with the two parts of each syllable having very similar entropy., Published as part of Tan, Ming Kai, Jin, Xingbao, Wang, Hanqiang, Japir, Razy & Chung, Arthur Y.

PHILIPPINES Distribution. Philippines Archipelago, Malay Peninsula (SINGAPORE, Pahang) Remarks. This species was recorded from Singapore according to Chopard (1969). Despite my having encountered it from the Philippines (Tan et al., 2020) and that this species is distinct from other congeners and Aphonoidini reported here, I have not encountered in recent surveys in Singapore (including Tan, 2012, 2017). Tan et al. (2020) also suggested that multiple species from different parts of Philippines may have be considered together as M. gracilis.

At least parts of the ectoparameres of the specimens from Singapore appear to share closer similarities with M. pangrango.
