Material: two specimens from L5 (one specimen PMBBU 23860)

Description: Scalarifom conical shell consisting of five whorls; up to 2.30 mm in height and 1.25 mm in width. Poorly preserved protoconch; thus, transition towards teleoconch or ornamentation could not be observed. Teleoconch with convex whorls separated by a strongly incised suture. Ornamentation consis of strong varicate axial ribs intersected by fine spiral threads. The interspaces between spiral threads are covered by extremely fine spiral threads. The last whorl represents about 65% of the total shell height. It is ornamented by 12 axial ribs intersected by seven spiral threads. Of these, two are very pronounced; they represent the ornamentation of the shell basis. Rounded aperture with strongly thickened holostome-type peristome.

Distribution: identified in: Austria (Kowalke and Harzhauser, 2004), Poland (Friedberg, 1954; Bałuk, 1975; Krach, 1981), Romania (Nicorici, 1973; Garilli and Parrinello, 2012).
