Differential diagnosis

Cochlostoma (T.) mnelense has a female genital morphology with a long, almost tubular and slim seminal receptacle, whereas it is short, with a simplified loop path, in the new taxon. Cochlostoma (T.) muranyii sp. nov. has much thinner and regular ribs. Although often not clearly visible, in C. (T.) kontschani sp. nov. the columellar lobe is deeply indented.

Etymology

The species is dedicated to Jenő Kontschán, a leading figure in Hungarian agro-zoological research, once an enthusiastic mite taxonomist, who used to have time to participate in some of the field trips where this species was collected.

Type locality

Description

SHELL. Closely spaced riblets on last part of protoconch. Teleoconch spotless, with rather strong ribs. Quite developed and strong lip with wide, abruptly inwardly curved or indented columellar lobe covering umbilicus.

MEASUREMENTS. 16 ♀♀: whorls =7.1–8, H = 7.1–8.8 mm, H/W=2.42–3.05, roundness=0.13–0.2, ribs incl.= 54–68°, apert. incl.= 13–24°, ribs/mm 1 st wh.= 4–12, ribs/mm 4 th wh.=6–15.

FEMALE GENITAL ORGANS. Ventral connection of pedunculus to bursa copulatrix. Short seminal receptacle confined to ventral side of body with 2–3 loops close to apex. Junction of uterus gland close to connetion between distal oviduct and pedunculus.

Remarks

These samples come from an area located in the Burrel and Dibrë districts. They are closely related with each other (p-distances =0.0–0.5%). The samples from “Pr. i Setës” have a very distinctive shell morphology ( Fig. 52F ).
