“Drepanodontus new genus
Type Species: Drepanodontus tatyanae new species, by original designation.
Description: Protoconch eroded. Shell large (to 56 mm), thin, strongly fusiform, with long, broad, open siphonal canal. Early whorls straight to concave, subsequently becoming convex. Whorls lacking shoulder, final whorl evenly convex from suture to distinct peripheral cord, evenly concave from peripheral cord to tip of siphonal canal. Sculpture of axial growth lines, most pronounced on early whorls, and strong, evenly spaced spiral cords. Aperture large, narrow, elliptical. Outer lip not reflected. Parietal region broad posteriorly, columella shorter than siphonal fold. Periostracum lamellose. Operculum large (~0.82 AL), oval, thin, translucent, with terminal nucleus. Head medium-sized, with short, stout tentacles, large eyes. Kidney large. Buccal mass small, odontophoral cartilages short. Rachidian teeth variable, tricuspid, cusps may be fused to appear monocuspid, or supplemental denticles or cusps may be present in some specimens. Lateral teeth with single, large, sickle-shaped cusp that may have one or more denticles. Salivary glands not fused, right gland much larger than left. Gland of Leiblein long, glandular anteriorly, tapering, flaccid posteriorly. Oesophagus broadens to form crop, constricts before entering very large, U-shaped stomach that lacks posterior mixing area.
Etymology: Drepane (Gr.)—sickle, odontos (Gr.)—tooth. The name reflects the very unusual sickle shape of the lateral teeth, consisting of a long, narrow basal plate with a single, long, recurved outer cusp, often with one or more denticles along its inner edge.”
