Description: Conical-elongated shell consisting of six whorls reaching up to 3 mm in height and 1.5 mm in width. The protoconch is build-up of 2.25 convex whorls. The teleoconch displays convex whorls separated by an incised suture. Ornamentation consists of prominent axial ribs that become more convex over the suture. On the last whorls, in their lower half, one can notice fine spiral threads, more obvious on the last whorl. This latter represents about 55% of the total shell height and is ornamented with 12 axial ribs. Oval aperture, the inner lip covers the umbilicus while the external lip displays varices.
Distribution: identified in Austria ( Kowalke and Harzhauser, 2004), Poland ( Bałuk, 1975).
