Description (after Gittenberger 1973).—Shell very slender, fusiform or somewhat cylindro-conical, with 8¼–9⅝ weakly to moderately inflated whorls, sculptured with more or less regularly placed, weak to strong axial ribs. Body whorl obliquely flattened, not or only slightly narrowed, with a very indistinct keel and a very short basis. Palatalis superior accompanied by an external indentation in the apertural lip. Palatal side of the aperture slightly leaning forward (in lateral view). Umbilicus narrowly open. Shell height, 6.0– 11.3 mm; width, 2.0– 2.9 mm.

Apertural lip moderately thickened; its parietal edges connected by a very faint callus. Angularis not connected with spiralis, a short subangularis is present. Parietalis well developed, situated deep inside body whorl and not visible in frontal view. Infraparietalis only present when there are more weak folds on the apertural lip. Columellar lamellae weakly developed, reaching hardly beyond the columella. Infrapalatalis, palatalis inferior and palatalis superior are more or less indented or interrupted, reaching up to the edge of the aperture. Suprapalatalis and weak suturalis present at dorsal to posterodorsal palatal center.
