description: Genus <i>Oxymeris</i> Dall, 1903 (Fig. 6 F–H) <i>Type species:</i> <i>Buccinum maculatum</i> Linnaeus, 1758; OD. <i>Synonyms</i>: <i>Abretia</i> H. &amp; A. Adams, 1853 (invalid, junior homonym of <i>Abretia</i> Rafinesque, 1814; type species <i>Terebra cerithina</i> Lamarck, 1822; SD, Dall, 1908); <i>Abretiella</i> Bartsch, 1923 (replacement name for <i>Abretia</i> H. &amp; A. Adams, 1853; type species <i>Terebra cerithina</i> Lamarck, 1822; by typification of replaced name); <i>Nototerebra</i> Cotton, 1947 (type species <i>Terebra albida</i> Gray, 1834; OD). <i>Definition:</i> Includes all species in clade B of Modica <i>et al.</i> (2019), and those that show a combination of conchological, anatomical and distribution features closely comparable with <i>Oxymeris maculata</i> or any genetically proven member of the clade. <i>Diagnosis</i>: Diagnostic nucleotide combinations in Table 5. <i>Shell</i>: 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. <i>Anatomy</i>: Rhynchodeal introvert very large, proboscis absent or vestigial, salivary glands absent or very small, radula venom gland and accessory proboscis structure absent. <i>Distribution:</i> Indo-Pacific, tropical East Pacific, West Africa. <i>Remarks</i>: Species of <i>Oxymeris</i> 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. <i>O. cerithina</i>) have a spire with convex sides and superficially resemble medium-sized <i>Punctoterebra</i> and <i>Myurella</i> species. However, in most cases (except <i>O. crenulata</i>), the <i>Oxymeris</i> 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 <i>Punctoterebra</i>, <i>Myurella</i> and most other terebrid genera. Finally, widely spaced deep spiral grooves differentiate <i>Perirhoe</i> from <i>Oxymeris</i>. <i>Included species:</i> <i>Oxymeris albida</i> (Gray, 1834) 2; <i>O. areolata</i> (Link, 1807) 1; <i>O. barbieri</i> (Aubry, 2008) 2; <i>O. caledonica</i> (G. B. Sowerby III, 1909) 1; <i>O. cerithina</i> (Lamarck, 1822) 1; <i>O. chlorata</i> (Lamarck, 1822) 1; <i>O. consors</i> (Hinds, 1844) 1; <i>O. crenulata</i> (Linnaeus, 1758) 1; <i>O. dillwynii</i> (Deshayes, 1859) 2; <i>O. dimidiata</i> (Linnaeus, 1758) 1; <i>O. fatua</i> (Hinds, 1844) 2; <i>O. felina</i> (Dillwyn, 1817) 1; <i>O. gouldi</i> (Deshayes, 1857) 2; <i>O. lineopunctata</i> (Bozzetti, 2008) 2; <i>O. maculata</i> (Linnaeus, 1758) 1; <i>O. ngai</i> Thach, 20162; <i>O. senegalensis</i> (Lamarck, 1822) 2; <i>O. strigata</i> (G. B. Sowerby I, 1825) 1; <i>O. suffusa</i> (Pease, 1869) 2; <i>O. swinneni</i> Terryn &amp; Ryall, 20142; <i>O. trochlea</i> (Deshayes, 1857) 2; <i>O. troendlei</i> (Bratcher, 1981) 1.
