Figs 105 (blue dot), 107

Pomatias martensianus Möllendorff, 1873: 56–57 .

Lectotype

BOSNIA AND HERZEGOVINA • probably ♀; “ Pomatias (Auritus) martensianus Mlldrf, Lipeta Herzegovina ”; SMF160548 /1.

Type locality

BOSNIA AND HERZEGOVINA • 1- Lipeta and Porim Mountains.

Description

SHELL. Teleoconch spotless, with rounded often whitish ribs more closely spaced on body whorl. Welldeveloped and strong lip with inwardly bent columellar lobe presumably (only seen in frontal and lateral view in picture) covering umbilicus.

MEASUREMENTS. 1 ♂, SMF160548/1: whorls=7.5, H =6.1, H/W=2.54, roundness= 0.11, ribs incl.=60°, apert. incl.=18°, ribs/mm 1 st wh. =20, ribs/mm 4 th wh.= 16.

FEMALE GENITAL ORGANS. Not seen.

Remarks

Because the lectotype is a male specimen, its measurements and features cannot be compared. This species occurs in a poorly explored area from which we have no samples. Based on the morphology of the lectotype, it is not plausible that it is a subspecies of C. (T.) gracile as currently reported.
