(Figs. 1 –2)

Cyclostoma consobrinum: Sandberger, 1874: 606 (pl. 29, fig. 33a [non 33b–c]).

Pomatias consobrinum: Wenz, 1923: 1805; Schütt, 1967: 201; Schlickum, 1976: 2 (pl. 1, fig. 1); Gall, 1980: 67; Stworzewicz, 1995: 26.

Pomatias consorbinum [sic]: Kókay, 2006: 34 (pl. 4, fig. 3).

Material examined. BSPG 1952 XVIII 17 (14 spcm., 29 opercula), 44 (1 spcm.).

Description. Shell medium-sized, trochiform. Protoconch (~1½ whorl) smooth; transition to teleoconch clear.

Teleoconch sculpture reticulated, with stronger spiral ribs and weaker axial ribs; distance between spiral ribs equal to twice their width; distance between axial ribs roughly equal to their width. Whorl profile greatly convex; spire stepped. Suture deep. Aperture rounded. Umbilicus narrow. Operculum with spiral growth.

Previous identification of the material. Gall (1980: Nr. 32 and 33): respectively, Pomatias consobrinum (Sandberger) and Pomatias sp.

Discussion. The present specimens compare well with P. consobrina, being easily identified by its size and strong reticulate sculpture (Stworzewicz 1995; Kókay 2006). The species is known from the Middle Miocene (MN 5–8) of Germany, Hungary and Austria (Schlickum 1976; Kókay 2006).

Paleoecological remarks. Recent species live in forests or shrublands, with more humid soil where they can burrow (Welter-Schultes 2012).
