Other specimens

CROATIA • 1- Klek Mt , close to the top (topotypical); 45.259° N, 15.1404° E; 2009; De Mattia and Zallot leg.; EZ0069 • 2- Klek Mt Cliffs halfway (topotypical); 45.2544° N, 15.1456° E; 2009; De Mattia and Zallot leg.; EZ0068 .

Type locality

CROATIA • Karlovac County, Mount Klek.

Description

SHELL. Closely spaced riblets on last part of protoconch. Teleoconch spotless, ribbed with not prominent and closely spaced ribs almost disappearing toward aperture. Moderately developed lip with flat columellar lobe. Umbilicus visible but narrower than in C. (T.) elegans .

MEASUREMENTS. 8 ♀♀: whorls =6.7–7.2, H = 6.2–7.7 mm, H/W=2.25–2.44, roundness=0.09–0.13, ribs incl.= 48–56°, apert. incl.= 20–24°, ribs/mm 1 st wh.= 7–14, ribs/mm 4 th wh.=9–13.

FEMALE GENITAL ORGANS. As in C. (T.) nanum .

Remarks

The specimens reported in Welter-Schultes (2012: 92) do not belong to this species. Cochlostoma (T.) braueri has a flat columellar lobe with the umbilicus visible. The illustrated specimen has a curved columellar lobe obstructing the umbilicus. The ribbing of the types and of fresh specimens from the type locality is different too. As far as known, this species lives only on Mount Klek.
