Descrição original:

(Vagvolgyi, 1977): “The  shell has a slender, conical spire with slightly convex outlines; height 10.4-12.8 mm, width, 5.7-7.1 mm; it consists of 5.7-6.6, moderately convex whorls, of which the first 1.7-2.0 form the embryonic shell. The umbilicus is very narrow, 0.3-0.7 mm in diameter at its opening, partly covered by the reflection of the columellar lip. The color of the fresh shell is brown, usually with a light band on the periphery of the last whorl. The sculpture of the embryonic whorls consists of widely separated, fine, transverse riblets, 12-16 per mm near the end of the first embryonic whorl, 12-20, near that of the second; the postembryonic whorls are smooth and lustrous, with 12-16 weak, intermittent spiral lines on the last whorl. The aperture is narrow oval, sometimes angular at its base, the lips are thin, the columellar lip reflected; there are no teeth or lamellae present in the aperture.”
