Description: Elongated conical shell consisting of six whorls; up to 3.25 mm in heights and 1.60 mm in width. Protoconch consisting of about 2.75 convex whorls ornamented with spiral threads. Teleoconch with slightly convex whorls and canaliculate suture. Ornamentation consisting of axial ribs intersected by spiral threads of equal intensity. This leads to the formation of a reticulated network with sharp knots at the intersection. The last whorl is about 65% of the total shell; ornamented with 16–21 axial ribs and six spiral threads. Two additional well-defined spiral threads are noticeable towards the base. Drop-like aperture; the inner lip covers the umbilicus, external lip shows an external varix and inner denticles.
Distribution: identified in Poland ( Friedberg, 1954; Bałuk, 1975; Krach, 1981), Hungary ( Strausz, 1966), Austria ( Kowalke and Harzhauser, 2004).
