Paladilhiopsis grobbeni Kuščer, 1928 , fig. 2

Paladilhia (Paladilhiopsis) robiciana grobbeni ( Kuščer, 1928) — Schütt 1970: figs. 10–12.

Material examined: ZMUJ2121–ZMUJ2122

Diagnosis: shell differs from that of B. robiciana ( Clessin, 1882) by larger size, markedly narrower spire, more pointed apex, aperture higher and wider, sometimes more oblique, the edge of the aperture more curved.

Described from the cave Raja peč, near Sevnica, E Slovenia, and springs in the surrounding area ( Slapnik 1995, 2010). As it is believed to be restricted to these sites, this species is considered to be 'Rare' in the Red List of Threatened Species in Slovenia ( Bole & Velkovrh 1986, Bole 1992). We have studied the topotypes, and the shell of P. grobbeni is unique, and unlikely to be erroneously identified. They were similar to the ones photographed by Schütt (1970) and Slapnik (1995).
