Material: 44 specimens, 19 from L5, 11 from Lp2 and 14 Lp10 (one specimen PMBBU 23856 )

Description: Conical shell with 5-6 whorls; up to 2.25 mm in height and 1.37 mm in width. In adult specimens, the protoconch is only partly preserved; juvenile specimens show protoconch with two convex whorls ornamented with fine spiral threads. Teleoconch with slightly convex whorls and canaliculate suture. The last whorl is about 70% of the total shell height. It is ornamented with more-pronounced 16-20 axial ribs intersected by 6 spiral threads. Towards the base, additional 3-4 spiral threads. Oval aperture, slightly sharper towards the top. The inner lip partly covers the umbilicus while the external one shows inner denticles and external varix.

Distribution: identified in Austria ( Kowalke and Harzhauser, 2004), Poland ( Friedberg, 1954; Bałuk, 1975; Krach, 1981), Hungary ( Strausz, 1966), Romania ( Rado, 1971; Popa and Ianoliu, 2000).
