Material – 23 specimens.

Description – Shell biconical, small (SL: 5–11). Spire high, outline straight. Teleoconch sutural ramps slightly concave, ornamented with two fine grooves in the middle. Shoulder angular, finely tuberculate on some specimens. Body whorl conical, outline straight to sigmoid, smooth with spiral ridges at the base or entirely covered with regularly spaced, fine spiral ridges. Subsutural flexure symmetrically curved, of moderate depth.

Remarks – The Letkés material agrees with the holotype (figured by PAVIA 1976, pl. 2, fig. 12), and with the specimens represented from other Hungarian localities. The species occurs in two phenotypically different forms. The typical form is ornamented by spiral rows of granulations on the body whorl (see the holotype, and BAŁUK 1997, pl. 20, figs 2–4), while the characteristic Central Paratethyan form has mainly smooth, and finely striate shell ( STRAUSZ 1966; BAŁUK l. c., pl. 20, fig. 1).

Distribution – France (M), Italy (M-P), Austria, Bosnia, Bulgaria, Czech Republic, Poland, Romania, Slovakia, Ukraine (MM). Hungary: Bánd, Borsodbóta, Letkés, Szob (MM).
