Type locality.

Albania, rocks along the road Hani i Hotit to Vermosh, 7.2-7.8 km north of the junction, 370 m a.s.l., 42°22.451'N, 19°27.507'E.

Diagnosis.

Protoconch glossy; aperture without teeth.

Measurements. SW: 3.6-4.2 mm (median = 4.0 mm), SH: 1.9-2.2 mm (median = 2.1 mm), AW: 1.5-1.7 mm (median = 1.6 mm), AH: 1.3-1.6 mm (median = 1.4 mm), (n = 6; largest and smallest specimens of multiple populations measured).

Differential diagnosis.

This new subspecies differs from the nominotypical subspecies in the following traits: aperture relatively larger, and its basal area not straight; apertural barriers (teeth) absent; protoconch smooth, glossy; ribs somewhat less dense (rib density on body whorl: 35-54).

Variation among specimens.

This subspecies shows some variability in terms of shell size and rib density.

Etymology.

This new subspecies is named after its toothless aperture, which distinguishes it from the nominotypical subspecies.

Distribution.

This taxon is found in the northeastern part of the Lake Shkodër Basin (Figure 4).
