Diagnosis
Protoconch fully immersed within the shell. Columellar region of aperture platform-like, with a sharp adapical fold.
Description
Shell acteonoid, thick, elongated; last whorl with slightly rounded profile; imperforate; D/ H ca. 0.5. Spire with slightly rounded whorls and faintly step-like profile; suture distinctly marked. Protoconch indistinct, nucleus fully immersed (Figures 1 (g) and 2(h)). Teleoconch with ca. 4.5 whorls, entirely sculptured by narrow punctuated spiral grooves; grooves are more numerous in later whorls and more closely packed together towards umbilicus (Figures 1 (c) and 2(c)). Grooves composed of small rounded-rectangular punctae, partially fused to the next one within each groove; punctae remain individually distinct or more completely fuse with their neighbours (Figures 1 (f) and 2(g)). Aperture anteriorly rounded, slightly narrowed posteriorly; parietal region with thin well-delimited callus; columellar region broad, slightly expanded, with a sharp edge, bearing a thickened adapical fold; outer lip sharp, thickened externally.
