The vision of 2030STEM is to address systemic barriers in institutional structures and funding mechanisms required to achieve full inclusion in Science, Technology, Engineering, and Mathematics (STEM) and provide leadership opportunities for individuals from underrepresented populations across STEM sectors. 2030STEM takes a systems-level approach to create a community of practice that affirms diverse cultural identities in STEM. This is the first in a series of white papers based on 2030STEM Salons - discussions that bring together visionary stakeholders in STEM to think about innovative ways to infuse justice, equity, diversity, and inclusion into the STEM ecosystem. Our salons identify solutions that come from those who have been most affected by systemic barriers in STEM. Our first salon focused on the power of social media to accelerate inclusion and diversity efforts in STEM. Social media campaigns, such as the #XinSTEM initiatives, are powerful new strategies for accelerating change towards inclusion and leadership by underrepresented communities in STEM. This white paper highlights how #XinSTEM campaigns are redefining community, and provides recommendations for how scientific and funding institutions can improve the STEM ecosystem by supporting the #XinSTEM movement., 13 pages, 2 Figures

Genus Oxymeris Dall, 1903 (Fig. 6 F–H) Type species: Buccinum maculatum Linnaeus, 1758; OD. Synonyms: Abretia H. & A. Adams, 1853 (invalid, junior homonym of Abretia Rafinesque, 1814; type species Terebra cerithina Lamarck, 1822; SD, Dall, 1908); Abretiella Bartsch, 1923 (replacement name for Abretia H. & A. Adams, 1853; type species Terebra cerithina Lamarck, 1822; by typification of replaced name); Nototerebra Cotton, 1947 (type species Terebra albida Gray, 1834; OD). Definition: Includes all species in clade B of Modica et al. (2019), and those that show a combination of conchological, anatomical and distribution features closely comparable with Oxymeris maculata or any genetically proven member of the clade. Diagnosis: Diagnostic nucleotide combinations in Table 5. Shell: Medium-sized to large, reaching 273 mm; weakly sculptured, typically with orthoconoid spire and rather wide aperture. Protoconch multispiral, 3–3.75 whorls. Sculpture of subsutural band, smooth or with regular crenulations; juvenile sculpture often consisting of axial ribs. Whorls flattened in outline; last adult whorl inflated; siphonal canal short, stout. Aperture wide, elliptic to rounded. Anatomy: Rhynchodeal introvert very large, proboscis absent or vestigial, salivary glands absent or very small, radula venom gland and accessory proboscis structure absent. Distribution: Indo-Pacific, tropical East Pacific, West Africa. Remarks: Species of Oxymeris are among the largest terebrids and can usually be easily identified by their large, shiny shells, with an orthoconoid or even slightly acuminate spire, often with a bulbous last whorl, a very wide aperture and a very short siphonal canal separated from the shell base by a deep groove. Nevertheless, some smaller species (e.g. O. cerithina) have a spire with convex sides and superficially resemble medium-sized Punctoterebra and Myurella species. However, in most cases (except O. crenulata), the Oxymeris species can be recognized by the complete lack of axial sculpture other than growth lines, while axial elements of varying strength and shape are present in Punctoterebra, Myurella and most other terebrid genera. Finally, widely spaced deep spiral grooves differentiate Perirhoe from Oxymeris. Included species: Oxymeris albida (Gray, 1834) 2; O. areolata (Link, 1807) 1; O. barbieri (Aubry, 2008) 2; O. caledonica (G. B.

Genus Profunditerebra new genus (Fig. 9 A–E) Type species: Profunditerebra papuaprofundi n. sp. Zoobank registration: urn:lsid:zoobank.org:act: A5A78A3D-AB11- 41C3-86F0-7C1451512FF4 Definition: Includes all species included in clade E3 of Modica et al. (2019) and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Profunditerebra papuaprofundi n. sp. or any genetically proven member of the clade. Diagnosis: Diagnostic nucleotide combinations provided in Table 8. Shell: Small to medium-sized (< 45 mm), with multispiral protoconch and slender siphonal canal. Whorls subcylindrical or flattened. Sculpture varying greatly; axial sculpture of rounded ribs, weak to very strong and elevated; spiral sculpture typically limited to striae in interstices and a subsutural groove, but may be absent or represented by strong cords generating overall cancellate pattern. Anatomy: Proboscis, radula, venom gland and salivary glands present. Radula of duplex marginal teeth (Fig. 9E). Accessory proboscis structure absent. Distribution: Almost exclusively deep water (typically 150–600 m) of tropical Indo-West Pacific from Taiwan to New Caledonia; one species known from shallow water of South Australia. Remarks: Profunditerebra is the only terebrine genus with duplex radular teeth similar to those in Pellifroniinae; however, members of the two groups can easily be differentiated by shell characters. Species of Profunditerebra can be separated into four clusters based on their shell morphology; however, only the first cluster corresponds to a phylogenetic lineage. Profunditerebra papuaprofundi n. sp. group. Shell uniformly coloured white to dark brown; heavily sculptured, with distinct subsutural groove and subcylindrical whorls. Sculpture of strong rounded ribs forming row of prominent nodules on subsutural band. Spiral sculpture of fine striae limited to interstices between axials, or overriding them to form fine continuous cords (including on subsutural band), or coarse cancellate pattern. Species of Neoterebra (e.g. N. armillata) exhibit a similar sculpture, but can be differentiated from Profunditerebra by their flattened whorls. The Punctoterebra textilis group also includes some similar forms (see Remarks on Punctoterebra). Profunditerebra orientalis group. Shell with flattened whorl profile; variegated colour pattern. Sculpture of fine orthocline ribs intersected by cords of about equal strength or slightly weaker than axials, to form delicate cancellate pattern. Subsutural band demarcated by shallow punctuate groove. Species of this group can easily be differentiated from congeners that either lack spiral elements, or display an overall much coarser sculpture. Both P. orientalis and P. hiscocki closely resemble species of Maculauger, from which they can confidently be differentiated only by anatomy (all studied species of Maculauger lack a radula) or molecular characters. Profunditerebra anseeuwi group. Shell with flattened whorl outline; subsutural band represented by short ribs or indentation. Sculpture of axial ribs, pronounced throughout whorl height, but weakening and becoming obsolete on later whorls; spiral sculpture absent. Species of this group are conchologically close to Duplicaria and to the Punctoterebra teramachii group; however, they can be differentiated from both by the overall weaker sculpture. In addition, these lineages can confidently be differentiated by the radular teeth morphology, Duplicaria having solid and recurved teeth, Profunditerebra duplex teeth and Punctoterebra flat teeth. Profunditerebra brazieri stands apart from other species in the genus, being endemic to temperate shallow water off Tasmania. Morphologically, it is close to the P. anseeuwi group, but has a very weakly defined subsutural band. Etymology: Name refers to the considerable depths at which almost all known species of the genus occur. Gender feminine. Included species: Profunditerebra anseeuwi (Terryn, 2005) 1 n. comb.; P. brazieri (Angas, 1871) 1 n. comb.; P. evelynae (Clench & Aguayo, 1939) 3 n. comb.; P. macclesfieldensis n. sp.

Neoterebra guadeloupensis Malcolm, Terryn & Fedosov newspecies (Fig. 13A, B) Type material: Holotype: MNHN IM-2013-61448, 1 lv, 17.2 mm; S Marie-Galante, Guadeloupe, 15 ° 50 'N, 61 ° 19 'W, 305–312 m (N/O Antea, KARUBENTHOS 2015 Stn DW4638). Paratypes 1–3: off Fajou, Guadeloupe, 16 ° 22 'N, 61 ° 34 ', 80 m (KARUBENTHOS 2012 Stn GD02). Paratype 1: MNHN IM-2013-20542, 1 lv, 6.5 mm. Paratype 2: MNHN IM-2013-20541, 1 lv, 5.7 mm. Paratype 3: MNHN IM-2013-20539, 1 lv, 10.4 mm. Paratype 4: MNHN IM-2013-9110, 1 lv, 7 × 2.1 mm; Port Louis, Guadeloupe, 16 ° 22 ' 46 'N, 61 ° 34 'W, 66 m (KARUBENTHOS 2012 Stn GD35). Zoobank registration: urn:lsid:zoobank.org:act: 57E995EE-24F0- 47A0-9DDC-E9D54948B056 Diagnostic nucleotide positions: Table 11. Description: Shell small. Protoconch multispiral, transparent with 3 whorls tinged yellow; protoconch/teleoconch transition clear-cut with visible sinusigera. Teleoconch of holotype with 15 whorls; overall whorl outline straight to convex. Weak axial sculpture of 15 narrow axial ribs with wider interspaces, increasing with maturity to 25 on penultimate whorl. Deep subsutural groove crossed obliquely by ribs. Subsutural band with strong elongate nodes; subsequently, 2 strongly projecting spiral cords at top and middle of whorl dominating sculpture, forming reticulate pattern of deep indentations with thin ribs; the upper cord projects in outline beyond subsutural band. On mature whorls interspaces sometimes with 1 or 2 weak spiral striae. Reticulate sculpture continuing on shell base. Aperture long with weak callus; columella with 2 weak folds. Shell lacks any pattern; coloured in shades of white to yellow. Habitat: Deep water, 60– 310 m. Distribution: Only known from off Guadeloupe. Etymology: Named after the type locality, the French Caribbean island of Guadeloupe. Remarks: Anumber of species of Terebridae have been described from the Western Atlantic and Caribbean Sea that have a similar strong reticulate sculpture. These include N. limatula that has more than 2 strong spiral cords in addition to the subsutural band (Fig. 13C) and a paucispiral protoconch. Neoterebra colombiensis is very similar to N. guadeloupensis n. sp., but the spiral sculpture in the former is less dominant, giving a more uniform reticulate sculpture with nodes at the intersections. In addition, N. colombiensis has a paucispiral protoconch in comparison with the multispiral protoconch of N. guadeloupensis n. sp. Neoterebra simonei is similar in colour and sculpture, but has 3 spiral cords in addition to the subsutural band and has a distinctive paucispiral protoconch of 1.5 whorls. Other similar species from the region, e.g. N. intumescyra and N. alagoensis (Fig. 9F), all have paucispiral protoconchs and different sculpture., Published as part of Fedosov, Alexander E, Malcolm, Gavin, Terryn, Yves, Gorson, Juliette, Modica, Maria Vittoria, Holford, Mandë & Puillandre, Nicolas, 2019, Phylogenetic classification of the family Terebridae (Neogastropoda: Conoidea), pp. 359-388 in Journal of Molluscan Studies The Malacological Society of London 85 (4) on pages 25-26, DOI: 10.1093/mollus/eyz004, http://zenodo.org/record/4469844

Genus Duplicaria Dall, 1908 (Fig. 3 A–E) Synonyms: Diplomeriza Dall, 1919 (unnecessary new name for Duplicaria Dall, 1908, treated by Dall as homonym of nonexistent ‘ Duplicaria Rafinesque, 1833 ’; type species Buccinum duplicatum Linnaeus, 1758, by typification of replaced name); Myurellisca Bartsch 1923, type species Myurella duplicatoides Bartsch, 1923, OD); Pervicacia Iredale, 1924 (type species Terebra ustulata Deshayes, 1857, OD). Type species: Buccinum duplicatum Linnaeus, 1758; OD. Definition: Primarily defined based on phylogenetic analysis, including all species in clade F1 of Modica etal. (2019) and, in addition, species that show shell morphology, anatomical or genetic characteristics closely comparable with Duplicaria duplicata or any genetically proven member of genus. Diagnosis. Diagnostic nucleotide combinations in Table 2. Shell: Elongate, small to large, 20–100 mm, with wide aperture, predominant axial sculpture, either continuous from suture to suture or interrupted by shallow to deep subsutural indentation. Spiral structure obsolete, sometimes microscopic striae or weak band joining nodes. Anatomy: Rhynchodeal introvert small; salivary glands and radular sac present; radula of solid curved marginal teeth attached to strong membrane. Venom gland, proboscis and accessory proboscis structure absent. Distribution: Tropical and subtropical Indo-Pacific, West Africa. Remarks: According to shell morphology, three distinct clusters can be delineated: Duplicaria duplicata group. Small to large shells, 25–100 mm; paucispiral protoconch; sculpture of strong axial ribs. Deep narrow spiral groove delineating distinct flattened subsutural band; no spiral sculpture. Whorl outline flattened, or shouldered due to elevated ribs below subsutural band. Duplicaria tristis group. Small shells, 10–30 mm; paucispiral protoconch; sculpture of strong axial ribs, subsutural area weakly impressed. Duplicaria tricincta group. Small shells, 10–25 mm; paucispiral protoconch; sculpture of strong spiral ribs. Amore convex shape with outline flattened due to elevation of ribs below subsutural area. Ribs weakening on mature whorls. Included species: Duplicaria albozonata (E. A. Smith, 1875) 2; D. australis (E. A.

Subfamily PELLIFRONIINAE new subfamily (Fig. 2) Type genus: Pellifronia Terryn & Holford, 2008 Zoobank registration: urn:lsid:zoobank.org:act: E827742C-E1B3- 42DD-B5EB-5D7EAA6E2C95 Diagnosis: Diagnostic nucleotide combinations in Table 1. Shell: Small to medium-sized (12–50 mm), with predominant axial sculpture. Early teleoconch whorls often with angled profile, later ones flattened or even slightly concave to convex. Sculpture of numerous close-set, evenly spaced, ribs, or forming raised nodules bordering upper or lower suture. Spiral sculpture absent or of very shallow, wide subsutural depression. Anatomy: Rhynchodeal introvert small; proboscis, radular sac, odontophore, salivary and venom glands well developed. Radula with well-developed membrane, bearing 2 rows of wide marginal teeth of duplex type. Accessory proboscis structure absent. Remarks: This subfamily comprises five described species in two genera, Bathyterebra and Pellifronia, that occur in the Indo-Pacific and Caribbean at bathyal depths. The anatomy of the studied species shows characters that are believed to be ancestral for Terebridae in general, i.e. weakly developed rhynchodeal introvert and radular teeth of duplex type (Castelin et al., 2012).

Genus Perirhoe Dall, 1908 (Fig. 10E) Type species: Perirhoe circumcincta (Deshayes, 1857); OD. Diagnosis: Shell small to medium-sized (< 50 mm), solid; axial sculpture weak to obsolete; spiral sculpture of irregular punctate groves; subsutural band weakly defined. Distribution: S Pacific, particularly New Caledonia. Remarks: Perirhoe is close to the genus Oxymeris in terms of shell proportions; however, it can be readily differentiated from species of the latter by the distinct spiral grooves throughout the whorls’ height. The sculpture pattern of widely set spiral grooves in Perirhoe resembles that in some species of Terebra, but the latter group has notably more slender shells, with higher spire and less robust siphonal canal. Included species: Perirhoe circumcincta (Deshayes, 1857) 4; Perirhoe valentinae (Aubry, 1999) 4 n. comb.

Genus Hastula H. Adams & A. Adams, 1858 (Fig. 6 A–E) Type species: Buccinum strigilatum Linnaeus, 1758; SD, Cossmann (1896). Synonyms: Impages E.A. Smith, 1873 (type species Terebra caerulescens Lamarck, 1822 = Buccinum hecticum Linnaeus, 1758; SD, Cossmann, 1896); Acuminia Dall, 1908 (type species Buccinum lanceatum Linnaeus, 1767; OD); Hastulina Oyama, 1961 (type species Terebra casta Hinds, 1844; OD); Egentelaria Rehder, 1980 (type species Terebra stylata Hinds, 1844; OD). Definition: Includes all species in clade D of Modica et al. (2019), and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Hastula strigilata or any genetically proven member of the clade. Diagnosis: Diagnostic nucleotide combinations provided for entire clade with exception of four specimens of H. albula (see Material and Methods) and, separately, for subclade H. albula – H. natalensis – H. aff. casta of clade D (Table 4). Shell: Small to medium-sized, shiny, 12–90 mm. Protoconch paucispiral or multispiral, about 1–5 whorls. Axial sculpture of crenulations on subsutural portion of whorl, or fine ribs on part or throughout whorl height; spiral sculpture of single subsutural groove, occasionally with additional row of punctations. Siphonal canal stout, very short, with well-developed fasciole. Aperture elongate to rounded. Genus Hastula (except four specimens of H. albula) Species/sequences analysed 18/91 Diagnostic nucleotides: 28: A, 67: T, 95: C, 181: T, 221: C, 222: C, 253: A, 581: T, 598: A Subclade H. albula – H. natalensis – H. aff. casta Anatomy: Rhynchodeal introvert, proboscis, venom gland, salivary glands and radula well developed. Radula of hypodermic marginal teeth attached to thin, reduced membrane; walls of marginal teeth often with multiple perforations (Fig. 6E, F) Species/sequences analysed 3/17 Diagnostic nucleotides 49: G, 347: C, 349: T, 517: T Distribution: Indo-Pacific, West Africa, Caribbean. Remarks: Species of Hastula are rather easy to recognize among Terebridae by their typically shiny shells, with fine close-set axial ribs and usually by the lack of a clearly defined subsutural band. The shell morphology in the Partecosta macleani group closely resembles that of Hastula; however, the latter is usually larger at maturity, while shells of comparable size can be differentiated by texture—a polished surface in Hastula vs dull in Partecosta. Furthermore, species of Hastula possess a venom gland and hypodermic radular teeth, whereas Partecosta species lack a venom gland and their radulae teeth are solid.

Protoconch paucispiral, 1.5 translucent whorls. Teleoconch of holotype with 14 whorls; outline of whorls slightly convex. Subsutural band formed of deep pits. Axial ribs narrow with wide interspaces; ribs c. 18–20 on penultimate whorl, straight on subsutural band, becoming oblique at subsutural groove, then curved on abapical part of whorls. Axial ribs intersected by 2–3 evenly spaced spiral grooves. Aperture long, with straight columella. Ground colour chalkywhite, sometimes with vague brown marks on subsutural band. Distribution: Only known from N Macclesfield Bank. Habitat: Depths of 160– 220 m. Etymology: Named after the South China Sea. Remarks: Maculauger campbelli has a similar protoconch and slender overall shape with slightly convex whorls, but in comparison with M. sudchinensis n. sp. has a more continuous subsutural groove, less pronounced sculpture, with 5–7 spiral grooves and a distinctive pattern of straw colour with random square spots. Maculauger sudchinensis n. sp. is similar to Terebra helichrysum (Fig. 13F), which however has a much shorter curved columella, a multispiral protoconch of 3.5 whorls, shorter whorls and a mottled orange colour pattern. Terebra levantina (Fig. 13G) has similar sculpture, but its whorls are much shorter, with 4–6 spiral grooves and it has a mottled colour pattern.

Zoobank registration: urn:lsid:zoobank.org:act: ABAFB4A7-FCD6- 4632-A07C-E9945D21EA7A Diagnostic nucleotide positions: see Table 11. Description (holotype): Shell of moderate size, to 42 mm. Protoconch of 4 narrow, conical whorls with small nucleus. Teleoconch of 12 whorls; teleoconch whorl outline convex constricted abapically at the suture. Subsutural groove represented by weak indentation on early whorls becoming sharper groove cutting through the ribs on mature whorls. Sculpture of strong slightly convex narrow axial ribs on subsutural band aligned with those on succeeding portion of whorls, varying significantly between specimens in spacing, and in number from 18 to 25 (20 ribs on penultimate whorl). No spiral sculpture in interspaces except for striae on base below periphery. Last whorl cup-shaped, becoming more elongate on mature specimens. Aperture wide with slight callus; columella straight with 2 folds. Colour off-white with tinges of yellow or pink with shiny white columella. Habitat: Depths of 350– 600 m. Distribution: Papua New Guinea, Solomon Islands and Taiwan. Etymology: Named after its deep-water habitat in Papua New Guinea. Remarks: The only sequenced specimen of P. papuaprofundi n. sp. with intact protoconch was designated as the holotype. It is notably smaller than the sequenced paratypes, which reach shell lengths of 42 mm. The larger specimens demonstrate the increased curvature of ribs and increased number and density of ribs to 25 on the penultimate whorl. Profunditerebra papuaprofundi n. sp. is phylogenetically closest to P. orientalis and P. anseeuwi. Profunditerebra anseeuwi has a weaker subsutural groove, straight and oblique ribs and a mottled colour pattern. Profunditerebra orientalis has more axial ribs, a mottled colour pattern, and a sculpture of ribs and spiral cords creating nodes at their intersections. Specimens of P. papuaprofundi n. sp. with more numerous curving ribs are similar to Maculauger cinctella and Terebra textilis (Salvador & Pickering, 2017). However, M. cinctella (Fig. 12C) has a shorter protoconch of 2.5 whorls, a much narrower noded subsutural band and many spiral striae within the interspaces between the ribs. In turn, T. textilis (Fig. 12D) differs in having a spiral groove defined by deep punctations or partially cutting the ribs, and has several spiral striae in the interspaces between the ribs., Published as part of Fedosov, Alexander E, Malcolm, Gavin, Terryn, Yves, Gorson, Juliette, Modica, Maria Vittoria, Holford, Mandë & Puillandre, Nicolas, 2019, Phylogenetic classification of the family Terebridae (Neogastropoda: Conoidea), pp. 359-388 in Journal of Molluscan Studies The Malacological Society of London 85 (4) on page 25, DOI: 10.1093/mollus/eyz004, http://zenodo.org/record/4469844, {"references":["SALVADOR, A. & PICKERING, J. 2017.

Genus Hastulopsis Oyama, 1961 (Fig. 10B) Type species: Terebra melanacme E. A. Smith, 1873; OD. Diagnosis: Shell small to medium-sized (to 60 mm), shiny, faintly axially ribbed, with numerous fine spiral incisions. Subsutural band generally not spirally decorated, bordered by relatively deep incision (Terryn, 2007). Distribution: Indian and western Pacific Oceans. Remarks: The genus comprises two groups of shallow-water species, one found from the eastern coast of Africa to the Arabian Gulf and another in waters of mainland Japan to Australia. Similar, but deeper-water species are found in the genus Maculauger n. gen., most of which can be recognized by having a row of large spots on the periphery. The species of Myurella have much stronger and more distinct sculpture features, and generally a brown basal area.

Genus Gradaterebra Cotton & Godfrey, 1932 (Fig. 10D) Type species: Gradaterebra scalariformis Cotton & Godfrey, 1932; OD. Diagnosis: Shell small (< 25 mm), often dull-coloured, with flattened tobulbouswhorls; axialsculptureof prominentribs; spiralsculpture absent, microscopic or represented by fine cords; last whorl inflated. Distribution: Indian and SW Pacific Oceans. Remarks. The genus mainly comprises small species from Australia and South Africa, which can be differentiated based on adult size < 25 mm. Included species: Gradaterebra scalariformis (Cotton & Godfrey, 1932) 4 n. comb.; G. assecla (Iredale, 1924) 4 n. comb.; G. capensis (E. A.

Genus Maculauger new genus (Fig. 7E, F) Type species: Terebra pseudopertusa Bratcher & Cernohorsky, 1985. Zoobank registration: urn:lsid:zoobank.org:act: 3565DB17-E4EF- 478B-8757-3A682BB8F6CF Definition: Includes all species included in clade E5A of Modica et al. (2019) and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Maculauger pseudopertusus or any genetically proven member of the clade. Diagnosis: Diagnostic nucleotide combinations in Table 10. Shell: Small to medium-sized (< 60 mm); typically, orange-brown with irregular maculations on subsutural band. Whorl outline flattened or gently convex. Subsutural band lightly ribbed or flattened, separated from lower portion of whorl by narrow groove or row of punctations. Axial and spiral sculpture of about equal strength, producing cancellate sculpture below subsutural band. Anatomy: Proboscis, radula, venom gland and accessory proboscis structure absent; salivary glands present or absent. Distribution: Indo-Pacific; subtidal and bathyal depths to about 600 m. Remarks: The new genus Maculauger comprises several species, formerly placed in Hastulopsis, that can be differentiated from similar species in Myurella by the equal prominence of spiral and axial spiral elements, producing a fine cancellate sculpture. Hastulopsis species have very weak sculpture and are found in the Indian Ocean or Japan. Some species of Maculauger, such as M. campbelli, are conchologically very close to Profunditerebra orientalis —a case where only anatomical and molecular characters can ensure correct identification (see Remarks on Profunditerebra). Etymology: The name combines ‘macula’ (Latin: spot, blotch), referring to the commonly maculated subsutural band in the species of the genus, with ‘auger’, the English epithet for Terebridae (‘auger shells’). Gender masculine. Included species: Maculauger alveolatus (Hinds, 1844) 1 n. comb.; M. campbelli (R. D. Burch, 1965) 1 n. comb.; M. castigatus (A. H. Cooke, 1885) 1 n. comb.; M. cinctella (Deshayes, 1859) 3 n. comb.; M. minipulcher (Bozzetti, 2008) 1 n. comb.; M. pseudopertusus (Bratcher & Cernohorsky, 1985) 1 n. comb.; M. sudchiniensis n. sp.

Genus Neoterebra new genus (Fig. 9 F–H) Type species: Terebra specillata Hinds, 1844. Zoobank registration: urn:lsid:zoobank.org:act: 68993F36-2AD1- 4DDE-A853-8832B4A9EE30 Definition: Includes all species included in clade E4 of Modica et al. (2019) and those that show a combination of conchological, anatomical and distribution characteristics closely comparable with Neoterebra specillata or any genetically proven member of the clade. Diagnosis: Diagnostic nucleotide combinations in Table 9. Shell: Small to medium-sized (< 60 mm); uniformly creamy-white to light brown or with pattern of brown blotches; pointed multispiral or paucispiral protoconch, 1.5 to about 3 whorls. Axial sculpture of orthocline or arcuate ribs, forming axially elongated subsutural nodules on well-defined band. Spiral sculpture from weak striae in interspaces between ribs to distinct cords, overriding ribs, often forming nodes at intersection or on lower portion of ribs. Last whorl typically abruptly constricted to siphonal canal. Canal clearly separated from shell base, bearing pronounced fasciole. Anatomy: Radula, proboscis, venom gland typically absent. Radula, when present, of hypodermic type. Salivary glands typically present. Accessory proboscis structure absent. Distribution: Tropical East Pacific, Caribbean, off Brazil; intertidal to upper bathyal depths, but typically shallow water. Remarks: Shallow-water species of Neoterebra differ from their congeners from deep water of Brazil and the Caribbean, being larger at maturity and sharing characteristic sculpture of strong axial ribs that form elevated, sometimes axially elongated nodules on the subsutural band. Caribbean species have a weaker subsutural band; those from deep water commonly lack a recognizable subsutural band and display a fine cancellate pattern of narrow axial riblets, intersected by spiral cords of equal strength. Although the affinity of Panamic and Caribbean species is suggested by the analysis of COI, further studies are needed to document relationships and delineate major groupings within the genus. Etymology: The name is a combination of neo (Latin: new) and Terebra, referring to the fact that species of this new genus only occur in the New World, constituting the majority of the terebrid fauna in the region.
