Distribution. It is endemic to the Azores. Remarks. A. angioyi lives in algal facies, more commonly in shallow waters, can reach 35 m depth (��vila, 2005: 51). The sculpture of the teleoconch is rather variable. It has three spiral cords above the aperture, rarely four. A common variant has weak or almost absent axial sculpture. It is very similar to A. canariensis, from which it differs in the protoconch sculpture, with marked spirals (��vila 2005)., Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on page 447, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["van Aartsen, J.

Checked data indicate a range from the westernmost Mediterranean Sea to southern Turkey in the Levant Basin (see Remarks and Fig. 3). It is common in shallow waters on hard bottoms with photophylous algae (Dantart et al. 1990; Giacobbe 2002; Gofas et al. 2011; Scaperrotta et al. 2012; ��zt��rk et al. 2014; Villari & Scuderi 2017). Live specimens are present in 0���50 m depth. Shells from deeper bottoms (e.g. from Cap Corse, France 600 m depth) probably drifted from shallower habitat (Bonfitto et al. 1994a; 1994b; Smriglio & Mariottini 1996). Found sympatric with A. sculptilis, A. sororcula, A. josefoi, A. scuderii, A. lucinae and A. pizzinii n. sp. Description (data on the neotype in parentheses). Shell (Figs 1 A���R; 2A���J; 14A���C; 15A���C) small for the genus, height 1.41���2.55 (1.9) mm, width 0.92���1.37 (1.15) mm, H/W ratio 1.553 ���1.951 (1.652), ovate-conical. Protoconch (Fig. 15B) paucispiral with nucleus moderately intorted, of 1.2���1.5 (1.2) whorls, height 0.250 ���0.320 (0.275) mm, nucleus diameter (d) 0.090 ���0.112 (0.100) mm, first half whorl diameter (Do) 0.200 ���0.220 (0.200) mm, maximum diameter (DM) 0.312 ���0.350 (0.325) mm; sculpture of a dozen parallel rows of rounded to broadly triangular microtubercles, sometimes fused, and occasional spiral threads in the interspaces (Fig. 15B). Protoconch-teleoconch boundary well marked. Teleoconch of 2.6���4.1 (3.2) convex whorls, with suture impressed. Axial sculpture on the last whorl of orthocline 11���20 ribs (16), plus the labial varix, narrower than the interspaces, gradually vanishing at the base. Spiral sculpture finer than axial, of equidistant cords, 7���9 (9) on the last whorl, of which 3���5 (4) above the aperture and 4���5 (5) on the base, 2���4 (3) on the penultimate whorl. Cords II and IV starting immediately after the protoconch-teleoconch boundary; cord III starting as a cordlet after 0.5���2 (0.5) whorl, gradually yet rapidly turning into a cord; cord I appearing at 1.2���2.5 (1.8) whorls (Table II); cord V rarely present (absent), appearing later. Small, rounded tubercles at the intersections, sometimes spinulose, especially on the first whorls; interspaces quadrangular. Microsculpture of growth lines and spiral threads overall (Fig. 15C). Umbilical chink absent or barely visible. Aperture pyriform, small, height 0.63���0.95 (0.75) mm, H/Ha ratio 2.312 ���2.949 (2.533), peristome continuous, outer varix modest, internally smooth. Colouration translucent yellowish, occasionally whitish, with darker spiral band at the base and quadrangular subsutural brown blotches; periphery and median columellar area whitish. Operculum typical for the genus, thin, corneous, paucispiral with eccentric nucleus. Soft parts (Figs 18 A���D): semi-transparent whitish background with dark-grey/black areas on head and snout (forming a sort of mask encircling eyes and mouth), opercular area, and on both sides of the body, extending and merging into a median band on the sole of foot. Yellow speckles on snout, merged in short stripes on head behind and in front of eyes, forming lines along cephalic tentacles, on foot, on opercular area and on propodium, and a yellow �� figure under the operculum; scattered white speckles on cephalic tentacles; 3���4 metapodial tentacles. Remarks (See also Table II and Figs 1 A���R; 2A���J; 3; 14A���C; 15A���C; 18A���D). Alvania scabra is known from most of the Mediterranean Sea (Material examined, and Fig. 3), and although major checklists of some countries do not report this species explicitly, it is frequently reported from neighbouring countries. For instance, neither B.D.D. (1884) nor Giribet & Pe��as (1997) reported it from France and Catalunia, respectively; however, it is rare, but present in Mediterranean France and at Baleares (see Material examined). It was not reported by Crocetta et al. (2019) for Lebanon, or by Pallary (1912) for Egypt, but it is known from southern Turkey and from Malta (Cachia et al. 1996). Cecalupo et al. (2008) did not report it from the Gulf of Gab��s but Fekih & Gougerot (1974) did report it from the Gulf of Tunis. A. scabra is strikingly variable in size, proportions and thickness of the shell, and in sculpture, with some degree of variation even within populations (Figs 1 I���N), and with almost all intermediates. The size of the protoconch microtubercles is variable. Rare specimens have stronger teleoconch spirals than the axials (Fig. 1N). In some specimens the tubercles are very small or absent (Fig. 1N), or so large that they tend to nearly fuse vertically into a rib (Fig. 1M). Colouration varies in the intensity of the background from whitish to yellowish, or yellow, and in the size and shape of the brown blotches, from dark quadrangular subsutural (Figs 1F, G), to pairs of smaller ones (Figs 1Q, R). Monochrome white (Fig. 2I), orange and brownish specimens are occasionally found (Figs 1L, 2H), as also are shells with short and fine dashed stripes on the base over the spirals or more rarely banded with two darker brown bands (Fig. 1H). The few observations on live animals revealed also some variation; specimens from Sicily (S. Giovanni Li Cuti, Catania, 4 m depth: Figs 18A, B) showed four metapodial tentacles, and darker and more intense black staining on the animal, with the lateral black stripes continuing almost uninterrupted on the foot-sole. The animal sketched by Serge Gofas (Malaga) from Southern Spain (Los Escullos, Cabo de Palos, H. 2.35 mm, AN29. MNHN: Figs 18C, D) showed three metapodial tentacles, lighter black staining on the animal, with the lateral black stripes reaching the foot-sole but not merging into continuous band. This is the type species of Alvaniella Sacco, 1895 ex Monterosato ms, currently regarded as a synonym of Alvania Risso, 1826. The type material of Rissoa scabra Philippi, 1844 is lost, having not been found in the Philippi collections either at MNHNS (Santiago de Chile) (Oscar Alfredo Galvez Herrera, Santiago de Chile, pers. comm. 2017) or at MNH (Berlin) (Christine Zorn, Berlin, pers. comm. 2017). The report of two syntypes (MNHNS 178) of A. scabra (Coan & Kabat 2017) was recently refuted by the curator (Oscar Alfredo Galvez Herrera, Santiago de Chile, pers. comm. 2018). These two non-typical specimens, belonging to the Philippi collection, are very worn and lack the protoconch. They are certainly not referable to A. scabra; the original label is lost and they most probably belong to the extra-Mediterranean fauna. Given the complexity of the present complex, and to stabilize the use of the name, we have selected a neotype, conforming to the original description, from Magnisi, Sicily (Monterosato coll. MCZR-M-22162/N) (Figs 1 A���C; 15A���C). Alvania oranica (Pallary, 1900) has either been considered a valid species (e.g. Pallary 1900; Giannuzzi Savelli et al. 2002; Tabanelli et al. 2011), or as a synonym of A. scabra (Philippi, 1844) (e.g. Amati 1985; CLEMAM 2015; WoRMS 2019), or finally as a synonym of A. sculptilis (Monterosato, 1877) (e.g. Tringali 2001; Gofas et al. 2011). Pallary (1900) stated that his A. oranica differs from A. scabra by the smaller size (H 2 mm), the stouter profile (not so evident in the original drawing), the last whorl larger and the different sculpture. However, the original description and figure of Alvania oranica (Pallary, 1900: 322, pl. VII, fig. 4) are not concordant with the syntypes found in the Monterosato collection (MCZR), which in turn show a remarkable morphological variation (Figs 2 A���J). The label, written by Pallary, reads: ��� Alv. oranica types���La figure qui a ��t�� donne�� dans les Coquilles Marins d���Oran est fort mauvaise et ne permet nullement la reconnaissance de l���esp��ce. J���ai donnerai une photographie dans ma 2�� editions. Pour M. de Monterosato��� [Alv. oranica types���The figure provided in the Coquilles Marins d���Oran is bad and does not allow the recognition of the species. I shall provide a photograph in my second edition. For Mr. de Monterosato]. Subsequently, Pallary (1920: 50, figs 20, 30) pictured two specimens of A. oranica from T��touan and Tangier, Morocco, that are more concordant with the types at MCZR. The shell in his fig. 30 (Fig. 2G) is somehow different, possibly being a mere Atlantic variety (Pallary 1920) or a distinct, still unidentified species. Since there have been difficulties in the past in identifying this species, and the type series available (there is no material at MNHN, Virginie Heros pers. comm. 3.ix.2019) includes at least one specimen of a different species, there is the need for a lectotype designation. To stabilize the name usage, we have selected as lectotype the shell, among the syntypes, best corresponding to the original description (Figs 2 A���C), also in consideration of Pallary���s subsequent remarks on the label. The following nomina nuda probably refer to this species: Alvania mutabilis Brusina, 1866: 27 ex Schwartz ms (nomen nudum), from Molat and Zadar (Dalmatia); Rissoa mutabilis Weinkauff, 1868: 311 ex Schwartz ms (nomen nudum), from Algeria; Rissoa mutabilis Monterosato, 1872: 36 ex Schwartz ms (nomen nudum), from Palermo, Ognina, Pantelleria and Algeria; Rissoa (Alvania) mutabilis Seguenza G., 1874: 4 ex Schwartz ms (nomen nudum); Rissoa mutabilis Aradas & Benoit, 1874: 201 ex Schwartz ms (nomen nudum), from?Sicily; Rissoa etnea Monterosato, 1884: 59 ex Aradas ms (nomen nudum), from Catania, Sicily; Alvania mutabilis Carus, 1893: 329 ex Schwartz ms (as synonym of the A. scabra) (nomen nudum), from several localities for A. scabra; Alvania sericea Parenzan, 1970: 78 ex Monterosato ms (as synonym of the A. scabra) (nomen nudum). Rissoa mutabilis Weinkauff, 1868 ex Schwartz ms has been regarded as either available and a synonym of A. scabra (Bogi, Coppini & Margelli 1983; WoRMS 2019), or a nomen nudum (van Aartsen 1982; Moolenbeek & H.J. Hoenselaar 1998). Actually, Weinkauff (1868) only reported, without any description, the record by Brusina (1866) from Dalmatia, which is also a nomen nudum, and his own findings in Algeria. Subsequently, this binomen was not made available by other authors (e.g. Monterosato 1872; G. Seguenza 1874; Aradas & Benoit; Carus 1893; all ex Schwartz ms), nor is our intention to make them available in this work. Specimens (see ���Other material examined���) in the Monterosato collection (ex Granata-Grillo coll. MCZR-M-22227: labelled ��� Ris. mutabilis Schw. ms. (Alv.)���, subsequently corrected into ��� R. scabra Ph. ���) (Fig. 1D, E) and in the G. Seguenza collection (MGUF, vertical showcase 153: labelled ��� Rissoa mutabilis Schw. ���), are in fact A. scabra. Rissoa schwartzii Aradas & Benoit, 1874 was introduced for A. scabra sensu Jeffreys (1856); Jeffreys & Capellini (1860); Tapparone Canefri (1869) non Philippi, 1844. It is probably a synonym of R. lanciae Calcara, 1845 (see B.D.D. 1884: 289; Monterosato 1884: 59; Priolo 1953: 72), and not of R. scabra Philippi as suggested by Monterosato (1878: 85; 1884: 59), but is anyway preoccupied by Rissoa schwartzi H��rnes, 1856 (currently Alvania schwartzi) (H��rnes 1856: 573, pl. 48, fig. 18; Kowalke & Harzhauser 2004: 121, 122, fig. 7D). No specimens under this name were found in the Aradas collection at MCSNM, although Priolo (1953) mentioned finding some among the material studied therein. Tabanelli et al. (2011) used the names Alvania cf. scabra (Philippi, 1844) and Alvania cf. oranica (Pallary, 1900) for Pliocene specimens that evidently may be referred to another species, Rissoa (Alvaniella) pagodulina Sacco, 1895 sensu Chirli & Linse (2011). Alvania cf. scabra sensu Tabanelli et al. (2011) differs from A. scabra (Philippi, 1844) by the protruding spiral cord III, that gives a keeled appearance to the whorls (particularly the last one), never so marked in A. scabra (but similar to what is obsereved in A. lucinae and A. leopardiana Brunetti & Vecchi, 2012), and for the presence of denticles on the inner side of the outer lip, never observed in A. scabra (despite their erroneous record in the original description by Philippi). Ponder (1985) used the name Alvania scabra (Philippi, 1844) for specimens from Madeira, probably corresponding to Alvania canariensis (d���Orbigny, 1840) (see also van Aartsen & van der Linden 1986; Moolenbeek & Hoenselaar 1989). Bitlis Bakir & ��zt��rk (2016: 446, 448, pl. 2, fig. 20) figured as A. scabra a subadult specimen of A. clarae Nofroni & Pizzini, 1991, recognizable by its cylindrical outline, the lack of the first subsutural cord producing more stepped whorls, the opisthocline axials (vs orthocline or sligthly prosocline in A. scabra), the tubercles at the intersections more spinose and directed toward the apex, the 3 spiral c, Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on pages 417-425, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["Philippi, R.

Distribution. Known from the Central-Western Mediterranean (Scaperrotta et al. 2012 as Alvania sororcula) (Fig. 13), where empty shells only have been collected at 20���280 m depth. The shells from deeper bottoms (Capraia Is., Italy, 110���280 m depth and off Fiumicino, Italy, 100���110 m depth) have quite probably been drifted from shallower bottoms. Found sympatric with A. scabra, A. lucinae, A. scuderii and A. sororcula. Diagnosis. Small shell with stepped outline, slightly turriculate. Whorls with wide subsutural ramp. Spiral microsculpture absent. Spiral cord V absent. Description (data on the holotype in parentheses). Shell (Figs 12 A���G; 17D���F) small for the genus, height 1.87���2.40 mm (2.30) mm, width 1.10���1.37 (1.25) mm, H/W ratio 1.65���1.84 (1.84), ovate-conical. Protoconch (Fig. 17E) paucispiral, with moderately twisted nucleus, of 1.3-1.5 (1.4) convex whorls, height 0.27���0.32 (0.32) mm, nucleus diameter 0.10���0.12 (0.11) mm, first half whorl diameter Do 0.20���0.24 (0.22) mm, maximum diameter DM 0.30���0.37 (0.35) mm. Sculpture of a dozen spiral rows of close-set, rounded microtubercles (Fig. 17E). Teleoconch of 3���4.1 (3.6) convex, angled whorls, suture impressed. Axial sculpture on the last whorl of 12���18 (18) slightly prosocline ribs plus the labial varix, narrower than the interspaces and sharply interrupted at the base. Spiral sculpture same strength as axial, of equidistant cords, 7���8 (8) on the last whorl, with 3 (3), exceptionally 4, above the aperture and 4���5 (5) on the base. Cords II and IV starting after protoconch/ teleoconch boundary; cord I absent; cord III appearing at 1.4���2 (1.45) whorls (Table VIII); wide subsutural ramp. Small rounded tubercles at the intersections; interspaces quadrangular. Microsculpture of only growth lines (Fig. 17F). Narrow umbilical chink. Subsutural ramp devoid of sculpture. Aperture pyriform, large, height 0.80���0.92 (0.90) mm, H/Ha ratio 2.34���2.70 (2.55), peristome continuous, smooth internally, thickened externally by a modest varix with sharp edge. Colouration translucent yellowish with large subsutural brownish quadrangular blotches. Operculum and soft parts unknown. Etymology. This species is named after Mauro Pizzini, our dear friend recently passed away who greatly contributed to micromollusc taxonomy. Remarks. The examined materials showed negligible morphological variation. Maximum height in the examined material 2.40 mm; Giannuzzi-Savelli et al. (2002: 113, figs 470, 471) reported (as A. sororcula) two conspecific shells from Bocche di Bonifacio, the largest stated as 3.4 mm high (which we suspect might be an error). In the specimens with the lowest H/W ratio the sculpture is usually more robust. The columellar wall sometimes covers the last spiral cord (VII). All examined specimens of A. pizzinii n. sp. (320 shells, including 212 adults) lacked cord I, with the exception of four specimens (4 adults out of 144 adult shells in the same sample) from Marettimo Is., with cord I appearing at 2.2���2.5 whorls. Some shells are monochrome yellowish-orange or brownish. A. pizzinii n. sp. differs from A. scabra by its stepped outline, the lack of spiral cord I (always present in A. scabra); the lack of spiral microsculpture on the teleoconch (always markedly present in A. scabra), the spiral cord V never present vs rarely present above the aperture in A. scabra. A. pizzinii n. sp. differs from A. sculptilis in having the cords II and IV starting after the protoconch/ teleoconch boundary; cord I not starting; cord III appearing at 1.4���2 whorls vs cords II, IV and V starting after the protoconch/ teleoconch boundary; cord III appearing at 2.2 whorls; cord I appearing after 1.2���2.5 whorl in A. sculptilis (or cords II and IV starting after protoconch/ teleoconch boundary; cord III appearing after 0.25���2 whorls; cord I starting after 1.2���2.5 whorl; cord V not starting). A. pizzinii n. sp. differs from A. lucinae in the protoconch sculpture of a dozen parallel rows of closely set, broadly rounded but not homogeneous microtubercles, vs ca. 10 parallel rows of broadly rounded but not homogeneous microtubercles, with spiral threadlets in the interspaces; teleoconch spiral cord I always absent vs always present in adults of A. lucinae; tubercles at the intersections small and rounded vs large and spinose, particularly on cord III in A. lucinae; spiral microsculpture absent on teleoconch vs present in A. lucinae. A. pizzinii n. sp. differs from A. sororcula by being more robust; the fewer axials on the last whorl (12���18 vs 25���29 in A. sororcula); teleoconch cord III appearing at 1.4���2 whorls vs 0.7���1 whorls in A. sororcula; cord I always absent vs always present in A. sororcula; spiral microsculpture absent on teleoconch vs present, weak on spiral cords in A. sororcula. A. pizzinii n. sp. differs from A. josefoi by its more slender outline; the teleoconch spiral cord I always absent vs always present in A. josefoi; fewer axials on the last whorl (12���18 vs 19���32 in A. josefoi); spiral microsculpture absent on teleoconch vs very fine spiral threadlets between the spiral cords in A. josefoi. A. pizzinii n. sp. differs from A. scuderii by its larger size (1.87���2.4 mm, mean 2.16 mm vs 1.55���2.1 mm, mean 1.81 mm in A. scuderii; colouration (translucent yellowish with large subsutural brownish quadrangular blotches, or monochrome orange-yellowish or brownish vs brownish background with dark brown spiral cords in A. scuderii); cord I always absent vs always present in A. scuderii. Three species of the Alvania scabra -complex are currently accepted from the eastern Atlantic, and are briefly discussed below for comparison: Alvania canariensis (d���Orbigny, 1840), Alvania angioyi van Aartsen, 1982, and Alvania grancanariensis Segers, 1999. Future studies may reveal more undescribed species, as happened with some other genera of rissoids (e.g. Alvania, Manzonia: Amati, 1987, 1992; Moolenbeek & Faber, 1987; Rol��n, 1987a, 1987b; Gofas, 1990, 2007, 2010; Rol��n, & Fernandes, 1990; Bouchet & War��n, 1993; Hoenselaar & Goud, 1998; Cordeiro & ��vila, 2015).

Empty shells in 1���11 m depth. Found sympatric with A. scabra, A. scuderii and A. pizzinii n. sp. Shells from deeper bottoms (50���500 m) probably drifted from shallower habitat (Bonfitto et al. 1994a; 1994b; Smriglio & Mariottini 1996). Description. Shell (Figs 6 A���N; 16A���C) small for the genus, height 1.65���2.55 mm, width 1.0��� 1.38 mm, H/W ratio 1.65���2.00, ovate-conical. Protoconch (Fig. 16B) paucispiral with nucleus moderately intorted, of 1.2���1.3 whorls, height 0.275 ���0.287 mm, nucleus diameter (d) 0.110 ���0.125 mm, first half whorl diameter (Do) 0.200 ��� 0.210 mm, maximum diameter (DM) 0.350 ���0.400 mm, sculpture of ca. 10 parallel rows of broadly rounded microtubercles (Fig 16B). Protoconch-teleoconch boundary well marked. Teleoconch of 2.75���3.75 slightly angled whorls, with suture impressed. Axial sculpture on the last whorl (when present) of 24���29 orthocline or slightly opisthocline ribs, plus the labial varix, narrower than the interspaces and gradually vanishing at the base. Spiral sculpture of equidistant cords, 7���9 on the last whorl, with 3���5 above the aperture and 4���5 on the base, 3���4 on the penultimate whorl, cords I and IV finer than II and II. Moderate subsutural ramp when cord I absent. Cords II and IV starting immediately after the protoconch-teleoconch boundary; cord I starting after 0.9���1.8 whorls or absent; cord III after 0.7���1.2 whorls (Table IV). Small, rounded tubercles at the intersections; interspaces quadrangular. Microsculpture of growth lines (more evident on the base) and spiral threads only on the spiral cords surface (Fig. 16C). Umbilical chink barely visible. Aperture pyriform, large, height 0.7���1.2 mm, H/Ha ratio 2.17���2.42, peristome continuous, outer varix modest, margin sharp, internally smooth. Colouration whitish-yellowish, with slightly prosocline quadrangular subsutural brown blotches; periphery and median columellar area whitish. Operculum typical for the genus, thin, corneous, paucispiral with eccentric nucleus. Body (Figs 18E, F) semi-transparent whitish with dark brown/grey areas on head and snout, darker on opercular area, fading on both sides of the body, extending only at edge of sole of foot. Yellow areas on both sides of the body merging towards the opercular area. Yellow speckles on snout, merged in short stripes on head behind and in front of eyes, forming lines along cephalic tentacles, on foot, on opercular area and on propodium, and a yellow �� figure under the operculum; scattered white speckles on cephalic tentacles; 4 metapodial tentacles. Remarks (See also Table IV and Figs 6 A���M; 10; 16A���C; 18E, F). Species not very variable (except for some large size shells corresponding to A. asperella, with on whorl more than usual, and the thickened labial varix). Granata-Grillo (1877a) described A. sororcula stating that the name was suggested by Monterosato (likely also the epithet asperella, as suggested by samples in the collection Monterosato, MCZR-M-autograph labelled ��� R. asperella inedita foss.? Messina���: Figs 6 I���J). See under A. scabra, A. sculptilis and A. pizzinii n. sp. for differences with these species. TABLE IV. Measurements of teleoconch and protoconch of Alvania sororcula in mm, with range, mean and standard deviation. 1 = syntype numbered 1 of A. sororcula; 2 = syntype of A. sororcula numbered 2; 3 = syntype of A. sororcula by USNM, Washington; 4 = Palermo; 5 = syntype numbered 1 of A. asperella; 6 = syntype of A. asperella numbered 2. Alvania sororcula differs from A. lucinae by the size (H 2.55 mm in A. sororcula vs 1.95 mm in A. lucinae); the tubercles at the intersections (small, rounded nodulose A. sororcula vs spinose or almost spinose in A. lucinae); the spiral cords (all the same strength in A. sororcula vs cord III more protruding in A. lucinae). A. sororcula differs from A. josefoi by the spiral microsculpture of the teleoconch: barely perceptible only on the spiral cords vs numerous, fine and spaced, seemingly striated threadlets in A. josefoi. A. sororcula differs from A. scuderii by the axial riblets on the last whorl (24���29 in A. sororcula vs 15���18 in A. scuderii); the appearance of the teleoconch spiral cords (cord III at 0.7���1 whorls, cord I when present at 1.8 whorls in A. sororcula vs cord I at 1.2���1.5 whorls, cord III at 1.5���1.8 whorls in A. scuderii); the shell colouration (yellowish-whitish, with quadrangular subsutural brown blotches in A. sororcula vs brownish background with dark brown spirals in A. scuderii)., Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on pages 431-434, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["Granata-Grillo, J.

Type Material. Holotype KBIN.28739, type 484; paratypes: 53 sh (Segers coll.), 7 sh (Swinnen coll.), 15 sh (Zorn coll.), 4 sh (ZMA), type locality: Maspalomas, Gran Canaria Is., Canary Islands. Material examined. Canary Islands: Gando (Gran Canaria Is.), 48 m depth, 5 sh (JT, JDO); Los Gigantes (Tenerife Is.), 10���35 m depth, xii.1994, 8 sh (CS-PM). Distribution. Canary Islands: Gran Canaria and Tenerife. Remarks. This species was originally described as having a robust shell, bright orange-yellow protoconch and first teleoconch whorls, translucent pale whitish-yellowish last teleoconch whorls. However, specimens with monochrome whitish shells or with pale subsutural brownish blotches, and with the protoconch nucleus brown, are not rare. Furthermore, the material examined and the figures in Rol��n et al. (2011: figs 39F, G) always show a spiral sculpture of four cords above the aperture (rarely 3), starting with two cords (not three as originally described). It is worth mentioning that the holotype of A. grancanariensis has two initial cords, whereas the specimen figured by Segers (1999: 82, fig. 2) with three cords was not part of the type material, and may belong to a different species. A. grancanariensis differ from A. canariensis in its lighter colour, with the first whorls of more or less intense orange; the dark spot on the protoconch nucleus, not marked; the more delicate sculpture on the teleoconch. It was sympatric with easily separable shells of A. canariensis. Concluding remarks We have revised the species of the Alvania scabra- complex with a focus on the Mediterranean Sea. Based on the scanty fossil record, the origin of this group seems younger than other lineages of Alvania (e.g. Alvania areolifera (Sandberger, 1863) (Garilli & Parrinello 2014) appearing in the Oligocene). We consider the following species to be valid: Alvania scabra (Philippi, 1844), Alvania sculptilis (Monterosato, 1877), Alvania sororcula Granata-Grillo, 1877, Alvania lucinae Oberling, 1970, Alvania josefoi Oliver & Templado, 2009, Alvania scuderii Villari, 2017 and Alvania pizzinii n. sp. All species have paucispiral protoconchs indicating non-planktotrophic larval development. Only A. scabra has a wide range, spanning almost the entire Mediterranean (with some local gaps to be checked). All other species have seemingly restricted ranges, and all are sympatric with A. scabra (Figs 3, 8, 10, 13)., Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on page 453, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["Segers, W.

The type material of Rissoa scabriuscula Requien, 1848 is lost (Pierre Moulet, Museum Requien, Avignon, pers. comm. 23.iv.2018) and the original description [���(27) Testa oblonga, acuta, alba, pellucida, anfractibus convexiusculis eleganter cingulatis, cingulis inferioribus ultimi anfractus simplicibus, superioribus granulato-muricatis, labro simplici. Long. 3. lat. 1 ��.���] is insufficient for a proper identification, making it a nomen dubium. Given the size indicated (3 mm), it may represent a form of A. pagodula (B.D.D., 1884) or A. rudis (Philippi, 1844). Monterosato (1878) referred it to A. weinkauffi Schwartz in Weinkauff, 1868 (that does not live along the Mediterranean French coast, though) and later (1884) to A. philippiana (Jeffreys, 1856) (= A. pagodula). See under A. scabra, A. sculptilis, A. sororcula and A. pizzinii sp. n. for the differences with these species. A. lucinae differs from A. josefoi by the teleoconch microsculpture (weak and sparse in A. lucinae vs fine and dense in A. josefoi); the tubercles at the intersections (large, spinose and protruding, especially the row on cord III, in A. lucinae vs small rounded tubercles in A. josefoi); the number of axials (13���16 in A. lucinae vs 19���32 in A josefoi); the colouration (whitish-yellowish with subsutural blotches, and periphery and median columellar area whitish in A. lucinae (rarely completely whitish) vs monochrome white, with the typical brown subsutural blotch before the varix in A. josefoi). A. lucinae differs from A. scuderii by the tubercles at the intersections (large, spinose and protruding, especially the row on cord III in A. lucinae vs small rounded tubercles in A. josefoi); the appearance of the spiral cords (cord III at 0.8���1 whorls, cord I at 1���2 whorls I A. lucinae vs cord III at 0.5���0.8 whorls, cord I at 1���1.5 whorls in A. josefoi)., Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on pages 434-436, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["Oberling, J.

About 20% of the specimens from Espardell Is. (Baleares) have cords II, III and IV starting after the protoconch/teleoconch boundary and cord I appearing at 1���1.5 whorls (Table VI). Few shells (2 out of 44 examined) show the subsutural brownish blotches typical of the A. scabra group, weaker than in the other species (Figs 14 D���F). Others lack even the blotch on the outer varix (19 shells out of 44 shells from Menorca and Ibiza, Baleares). See under A. scabra, A. sculptilis, A. sororcula, A. lucinae and A. pizzinii n. sp. for the differences with these species. TABLE VI.

Found sympatric with A. scabra and A. josefoi. Description. Shell (Figs 4 A���O; 5A���O; 15D���I) small for the genus, height 1.55���2.42 mm, width 0.91���1.4 mm, H/W ratio 1.607 ���1.967, ovate-conical. Protoconch (Figs 15E, H) paucispiral with nucleus moderately intorted, of 1.2���1.5 whorls, height 0.275 ���0.325 mm, nucleus diameter (d) 0.075 ���0.133 mm, first half whorl diameter (Do) 0.150 ���0.250 mm, maximum diameter (DM) 0.275 ���0.362 mm; sculpture of a dozen parallel rows of rounded to broadly triangular microtubercles, sometimes fused, and occasional spiral threads in the interspaces (Figs 15E, H). Protoconch-teleoconch boundary well marked. Teleoconch of 3���3.8 convex, slightly angled whorls, with suture impressed. Axial sculpture on the last whorl present or absent, of 10���20 orthocline or very slightly opisthocline ribs, plus the labial varix, narrower than the interspaces, gradually vanishing at the base. Spiral sculpture finer than the axial, of equidistant cords, 7���10 on the last whorl, with 3���5 above the aperture and 4���5 on the base, 2���3 on the penultimate whorl. Wide subsutural ramp devoid of spirals. Cords II, IV and V starting immediately after the protoconch-teleoconch boundary; cord III starting as a cordlet after 2.2 whorls, gradually yet rapidly turning into a cord; cord I appearing at 1.2���2.5 whorls (Table III), (or cords II and IV starting after the protoconch-teleoconch boundary; cord III appearing after 0.25���2 whorls; cord I starting after 1.2���2.5 whorl; cord V not starting). The casual examination of 41 shells showed, after the protoconch-teleoconch boundary, 3 spiral cords on 13 specimens and 2 spiral cords on 28 specimens. Small, rounded tubercles at the intersections; interspaces quadrangular. Microsculpture of growth lines and spiral threads on the whole surface (Figs 15F, I). Umbilical chink present or absent. Aperture pyriform, small, height 0.66���0.96 mm, H/Ha ratio 2.235���2.63, peristome continuous, outer varix modest, internally smooth. Colouration translucent whitish-yellowish, with quadrangular subsutural brown blotches; periphery and median columellar area whitish. Operculum typical for the genus, thin, corneous, paucispiral with eccentric nucleus. Soft parts unknown. Remarks (See also Table III and Figs 4 A���O; 5A���O; 15D���I). A. sculptilis is morphologically more variable than previously suggested, even within the same population (Figs 5 A���O), in size, proportions, outline and in the strength and disposition of sculpture. In most specimens the axial sculpture is lacking or very weak (often present only on the first teleoconch whorls). The tubercles at the intersections are variably evident, but very rarely spinose. Gofas et al. (2011: 183) considered A. oranica as a synonym of A. sculptilis, differing from the closely related A. scabra in its 3 spiral cords. Actually, A. sculptilis may also have 2 spirals on the first whorl and up to 5 above the aperture. Tringali (2001: 209) considered A. sculptilis and A. scabra easily diagnosable in the western Mediterranean based on the lack of the fourth abapical spiral cord in A. sculptilis and the protoconch with a more confused sculpture in A. sculptilis (vs more dome-shaped and with more regular rows of microtubercles in A. scabra). Tringali (2001: 210, figs 6���8) stressed the variability of A. sculptilis, with shells showing axial and spiral sculpture of the same strength, others with axials only on the first whorls (the last dominated by spirals), and finally shells almost devoid of axial sculpture. Noteworthy, A. scabra shows almost the same range of variation (Fig. 1N). Gofas et al. (2011: 183) considered the status of A. sculptilis vs A. scabra as unsettled, not excluding the possibility of a single very variable species. Conversely, Agamennone & Micali (2009: 4) considered the morphological difference and the geographic ���separation��� (albeit they are sympatric in the Western Mediterranean) as sufficient to separate the two species.

(Continued) Rissoa (Alvinia) conspicua Pallary, 1900 ex Monterosato, is a nomen nudum (���close to R. fischeri, but distinct���; Pallary, 1900; 1920). A specimen from Arzew, Oran (Algeria), one of the localities listed by Pallary, was found in the Monterosato collection (MCZR-M-30061). Albeit not a fresh shell, it clearly belongs to A. sculptilis (Figs 4 G���I). Alvania sculptilis (May, 1920) [Merelina sculptilis May, 1920: 62, pl. XV, fig. 15; Criscione & Ponder 2011] (Fig. 4P) is a junior secondary homonym of Alvania sculptilis (Monterosato, 1877). However, as already commented by Bouchet (2011), these two species may prove to belong to different genera when a robust phylogeny of Alvania s.l. becomes available. We thus agree that, for the time being, it is advisable to keep using the invalid name Alvania sculptilis (May, 1920) for the Australian species. See under A. scabra for the differences with this species. A. sculptilis differs from A. sororcula by the axial riblets on the last whorl (10���20 when present in A. sculptilis vs 25���29 in A. sororcula), and the teleoconch spiral microsculpture (spaced threadlets, more closely set only those on the spiral cords in A. sculptilis vs weaker and more spaced in A. sororcula). A. sculptilis differs from A. lucinae by the size (H 2.42 in A. sculptilis vs 1.95 mm in A. lucinae); the tubercles at the intersections (rounded nodulose, in A. sculptilis vs spinose or almost spinose in A. lucinae); the spiral cords (all the same strength in A. sculptilis vs cord III more protruding in A. lucinae). A. sculptilis differs from A. josefoi by the different teleoconch microsculpture (Figs 15E, F; H, I vs 16H, I) and the colouration (whitish-yellowish with subsutural blotches, and periphery and median columellar area whitish in A. sculptilis vs monochrome white, with the typical brown subsutural blotch before the varix in A. josefoi). A. sculptilis differs from A. scuderii by the axial riblets on the last whorl (10���20, when present in A. sculptilis vs 15���18 in A. scuderii); the spiral cords above the aperture (variable 3���5 cords in A. sculptilis vs always 4 cords in A. scuderii); the colouration (translucent yellowish-whitish, with darker spiral band at the base and quadrangular subsutural brown blotches in A. sculptilis vs brownish background with dark-brown spirals in A. scuderii). Some specimens of A. sculptilis with a slender, robust shell found along the southern Spanish coasts (Getares, Algeciras) are similar to A. pizzinii n. sp., but differ by their more robust and slender shell, the wider subsutural ramp and the visible umbilical chink., Published as part of Amati, Bruno, Appolloni, Massimo, Giulio, Andrea Di, Scuderi, Danilo, Smriglio, Carlo & Oliverio, Marco, 2020, Revision of the Recent Alvania scabra (Philippi, 1844) complex (Mollusca, Gastropoda Rissoidae) from the Mediterranean Sea with the description of a new species, pp. 415-458 in Zootaxa 4767 (3) on pages 425-431, DOI: 10.11646/zootaxa.4767.3.3, http://zenodo.org/record/3772979, {"references":["Monterosato, T.

Type locality. “Numerous localities” in Mediterranean and Atlantic. Remarks. Monterosato (1890b: 159) deemed Jeffreys’ (1867: 203; 1869: 214; pl. 77, fig. 4) interpretation of Eulima intermedia Cantraine, 1835, as not corresponding to Cantraine’s actual species [= Melanella polita (Linnaeus, 1758)]. He had previously described this form as Acicularia intermedia var. “ solidula ” (1884h: 103; nomen nudum in 1878c: 96). The name Eulima solidula, however, may fall in homonymy with Eulima solidula A. Adams & Reeve, 1850, and it may therefore be argued that Monterosato (1890b: 159) preferred to introduce by a description a different name, Acicularia lubrica for Eulima intermedia Cantraine sensu Jeffreys. This is a well– known species of the genus Melanella Bowdich, 1822, parasitic on holothurians (Bouchet & Warén, 1986: 352). It is noteworthy that in the type material and additional (non-type) samples in the collection the typical spiral microsculpture, assumed to be diagnostic of M. lubrica as currently conceived (e.g. Bouchet & Warén, 1986: 362, figs 742,743; Gofas et al., 2011: 228), is rather variable in presence/absence and strength.

Family DENTALIIDAE † brugnonei, Dentalium [Dentalium brugnonei Monterosato, 1891] (Figures 40E, F) 1891c: 15 [XL: 948]—available name Type material.

Ficarazzi” Type locality. Described from Ficarazzi † (Sicily). Remarks. Taxon introduced to replace Dentalium brevifissum Brugnone, 1876, not Deshayes, 1826. The types refer to Brugnone’s name. The name is followed by the mark “F.”, standing for the well–known Lower Pleistocene deposits of Ficarazzi (Palermo). Evidently unaware of Monterosato (1891), Steiner & Kabat (2004) highligthed the same homonymy and proposed the same replacement name for Dentalium brevifissum Brugnone, 1876, not Deshayes, 1826: i.e. Dentalium brugnonei Steiner & Kabat, 2004 [sic!]. Dentalium brugnonei and Dentalium brevifissum are both recorded by MolluscaBase (2018) as taxon inquirendum. It is a valid fossil species [new status]. † philippii, Dentalium [Fissidentalium rectum (Gmelin, 1791)] (Figures 40G, H) 1872a: 27 [V: 65]—available name Type material.

MCZR–M–25166 —8 sh “ Dentalium delessertianum Chenu fossili Pliocene Ficarazzi pr. Palermo” Type locality. Described from Monte Pellegrino † and Ficarazzi † (Sicily). Remarks. Recorded by MolluscaBase (2018) as taxon inquirendum. The name was introduced by means of an indication for Dentalium striatum Lamarck, 1818 [not Born, 1778], sensu Philippi (1844: 208). Later on Monterosato (1877c: 40) adopted the name Dentalium delessertianum Chenu, 1843, reporting his own D. philippii as a synonym. Monterosato’s name is a primary homonym of Dentalium philippii Chenu, 1843, already introduced for Dentalium striatum Lamarck, sensu Philippi. Therefore, like Dentalium delessertianum (Pilsbry & Sharp, 1898: 213; Caprotti, 1979: 223; Steiner & Kabat, 2004: 582, 630), Dentalium philippii Monterosato, 1872 is another junior synonym of Fissidentalium rectum (Gmelin, 1791) [new synonymy].

Described from Palermo, Magnisi, San Vito lo Capo and Messina (Sicily), Napoli (Italy), Roussillon (France), Algiers (Algeria). Remarks. Monterosato introduced this name with a brief description. He referred that the species matches the var. “ exilis ” Monterosato (nomen nudum) of Eulima distorta Deshayes 1830, and (with a question mark) Eulima distorta Deshayes 1830, sensu G.O. Sars (1878: pl. 11, fig. 23). We think that the introduction is valid due to the description rather than to the reference to Sars (1878). Thus, the type material is composed of the shells directly examined by Monterosato for this article. Pending a revision of the Mediterranean species of this difficult genus, it remains an open question whether this is a distinct species or not.

Civitavecchia (Italy) and Mediterranean. Remarks. Name proposed to distinguish Scalaria pseudoscalaris Brocchi, 1814 sensu Auctores, considered as a distinct species by Monterosato based on the lack of spines at the axials. The alleged synonymy with Scalaria lamellosa Lamarck, 1814 (from Western Atlantic) was initially considered as possible by Monterosato’s (1877d: 420) but subsequently (Monterosato, 1878c: 26) rejected. Some Authors have considered the introduction by Monterosato as a replacement name for Scalaria lamellosa Lamarck, 1822 [not Turbo lamellosum Brocchi, 1814 — now Cirsostrema lamellosum (Brocchi, 1814)]. Landau et al. (2006: 18) debated the issue of the name to use for the species, deciding for Epitonium commutatum (Monterosato) [now Gyroscala commutata]. Considering other cases of species from the two sides of the Atlantic almost indistinguishable morphologically (see e.g. Bulla striata Bruguière, 1792 v. B. occidentalis A. Adams, 1850: Malaquias & Reid, 2008) we take a conservative position in regarding the introduction by Monterosato (1877d: 420) as a new species. In case the two entities (Eastern v. Western Atlantic) are considered as conspecific, then the name for both should be Gyroscala commutata (Monterosato, 1877); in case they are proved (for instance by genetics) as distinct, then G. commutata should be restricted to the Eastern Atlantic species. Recorded by MolluscaBase (2018) as a synonym of Gyroscala lamellosa (Lamarck, 1822), we suggest reverting to Gyroscala commutata (Monterosato, 1877) as taxon inquirendum [new status]., Published as part of Appolloni, Massimo, Smriglio, Carlo, Amati, Bruno, Lugliè, Lorenzo, Nofroni, Italo, Tringali, Lionello P., Mariottini, Paolo & Oliverio, Marco, 2018, Catalogue of the primary types of marine molluscan taxa described by Tommaso Allery Di Maria, Marquis of Monterosato, deposited in the Museo Civico di Zoologia, Roma, pp. 1-138 in Zootaxa 4477 (1) on page 36, DOI: 10.11646/zootaxa.4477.1.1, http://zenodo.org/record/1454652, {"references":["Settepassi, F., Schiro, G. & Zanardi, G.

It is the type species of the subgenus Allerychiton Dell’Angelo & Oliverio, 1997 (by original designation). The name was made available by a description included in the important paper on Polyplacophora (1879c), but the manuscript name by Giuseppe Seguenza had already appeared as a nomen nudum in Monterosato (1878c: 77) and Tiberi (1879: 150). Gaglini (in Settepassi, 1985) figured the single specimen.

“ OPISTHOBRANCHIA ” The taxon Opisthobranchia P. Fischer, 1883, has been undergoing a constant critical revision during its history. In recent years there is increasing evidence that it will not survive the molecular revolution in molluscan systematics (Wägele et al., 2014), so that informal names as “sea slugs” may be provisionally adopted to refer to most “opisthobranch” taxa (e.g. Crocetta et al., 2015). Here, however, listing the material under “ Opisthobranchia ” is also convenient to follow the survey on the Monterosato material already provided by Oliverio & Tringali (2001)., Published as part of Appolloni, Massimo, Smriglio, Carlo, Amati, Bruno, Lugliè, Lorenzo, Nofroni, Italo, Tringali, Lionello P., Mariottini, Paolo & Oliverio, Marco, 2018, Catalogue of the primary types of marine molluscan taxa described by Tommaso Allery Di Maria, Marquis of Monterosato, deposited in the Museo Civico di Zoologia, Roma, pp. 1-138 in Zootaxa 4477 (1) on page 72, DOI: 10.11646/zootaxa.4477.1.1, http://zenodo.org/record/1454652, {"references":["Wagele, H., Klussmann - Kolb, A., Verbeek, E. & Schrodl, M.
