description: Genus <i>Bathyterebra</i> new genus (Fig. 2 E–I) <i>Type species:</i> <i>Terebra benthalis</i> Dall, 1889. <i>Zoobank registration:</i> urn:lsid:zoobank.org:act: EF1F9047-25AB- 4400-A1D4-C705B757E114 <i>Definition:</i> Includes species with combination of conchological, anatomical and distributional characteristics closely comparable with <i>Bathyterebra benthalis</i>, including all species in clade A2 of Modica <i>etal.</i> (2019) and any species proven to be a member of this clade. <i>Diagnosis</i>: Diagnostic nucleotide combinations in Table 1. <i>Shell</i>: Small, 12–30 mm, elongate, white to tan. Protoconch paucispiral, cyrthoconoid, about 1.5 glossy whorls. Sculpture of fine dense orthocline ribs, interrupted by depression in adapical portion of whorl. Axial ribs weakening towards anterior throughout their height on mature whorls, often forming weak nodules bordering adapical depression, giving distinctly angulated outline to early spire whorls; late teleoconch whorls gently convex. Last adult whorl evenly convex, transitioning to shell base without visible angulation. Siphonal canal stout, slightly recurved at tip, shallowly notched; siphonal fasciole weak or strong. Aperture elongate, wide. <i>Anatomy</i>: Rhynchodeal introvert small; proboscis, radular sac, salivary and venom glands well developed. Accessory proboscis structure absent. Radula with well-developed membrane, bearing 2 rows of wide marinal teeth of duplex type. <i>Distribution:</i> South China Sea, New Caledonia, Caribbean; bathyal depths. <i>Etymology</i>: Name refers to bathyal depths, at which three known species of the genus were sampled. Gender feminine. <i>Remarks: Bathyterebra</i> spp. can be differentiated from members of most other genera of Terebridae by the combination of relatively faint sculpture lacking spiral elements, weakly defined subsutural band and relatively high last adult whorl with convex outline. In shell proportions the genus resembles <i>Oxymeris</i>; however, the latter has more flattened whorls and typically can be easily differentiated by a larger size at maturity. <i>Included species:</i> <i>Bathyterebra benthalis</i> (Dall, 1889) 1 n. comb.; <i>B. coriolisi</i> (Aubry, 1999) 1 n. comb.; <i>B. zhongshaensis</i> Malcolm, Terryn &amp; Fedosov 1 n. sp.
