Diagnosis.

Shell medium to large, tumid and somewhat conical, light corneous. Lower whorls almost smooth to variably wrinkled, upper ones indistinctly wrinkled-costate. Neck strongly, irregularly costate. Relatively large peristome with simple margin. Lamellae superior and spiralis overlap. In front view lamella subcolumellaris occasionally visible. Lunella dorsal-dorsolateral to dorsolateral, mostly separate from the basalis. Subclaustralis short, sulcalis strong. Anterior plica superior weak, not connected to the lunella complex. Clausilium plate partly visible through the aperture.

Dimensions

(in mm). Hs: 14.9-21.7 (holotype 17.7), Ws: 3.9-5.4 (holotype 4.9).

Type locality.

Macedonia, valley of the Crni Drin, gorge above and W of Jablanica, about 25 km NNW of Struga.

Type material.

Type locality, leg. Šteffek, 28.vii.1985, holotype (HNHM 94891), paratypes (NHMUK 20050230, HNC 63194, HNHM 94892/2, NHMW 103292, RMNH 100321, SMF 328096).

Distribution.

Upper valley of the Crni Drin Valley in western Macedonia. The subspecies was collected only once at the type locality. Due to the vague locality data, during later attempts the site could not be found.

Remarks.

In Nordsieck’s (2009) opinion this taxon is closely related to " Montenegrina dofleini occidentalis ".
