Descrição original:

“Shell minute (height 2.0 mm, diameter 1.1 mm), sinistral, thin, elongate, conical in first whorls then cylindrical; colour white, subtranslucent. Whorls 5.2, inflated, strongly rounded, separated by a deep suture. Protoconch 1.5 whorls, smooth; protoconch/teleoconch transition distinct because of change in sculpture; surface of teleoconch with lamellate axial ribs (27 on body whorl) and distinct minute spiral striae between the ribs. Body whorl rounded, ventrolaterally with a distinct bulge through which an inner, palatal, crescent-shaped denticle can be seen.

Aperture almost circular; upper insertion of the peristome not descending; peristome continuous but the upper part largely merged to the preceding whorl, double, weakly expanded and thickened; there is a columellar lamella at the bottom of the columella, which can be fully seen only by looking through the aperture (also indistinctly visible in frontal view in the aperture); perforate, umbilicus marked by the continuation of the axial ribs. Operculum unknown.”
