Diagnosis.

Shell very small, light corneous. All whorls smooth. Neck finely striate, deep inflexed, with strong basal and peripheral crests. Peristome detached, projected, pear-shaped, with simple margin. Lamellae superior and spiralis overlap. In front view lamella inferior hidden or barely emerged. Subcolumellaris and clausilium plate barely visible through the aperture. Lunella dorsolateral-lateral, separate from the short to rudimentary basalis. Subclaustralis absent, sulcalis residual or absent. Anterior plica superior only exceptionally present, either fused to or separate from the lunella complex.

Type locality.

Albania. Mat District, 3 km W of the Qafa e Murrës, gorge of the Lumi i Varoshit near the Shkëmb i Skanderbeut, 970 m, 41.6465°N, 20.1898°E.

Type material.

Type locality, leg. ZE, ZF, JK, DM, 26.vi.2003, holotype (HNHM 94831), paratypes NHMUK 20050214/2, HNC 63178/2, HNHM 94832/229, NHMW 103272/2, RMNH 100319/2, SMF 328076/2, NMBE 534918/6).

Other material.

Type locality, leg. TD, ZE, ZF, DM, 11.x.2005 (HNHM 96824); Mirditë District, 2 km NE of Kurbnesh, 800 m, 41.7952°N, 20.1117°E, leg. ZF, DM, ZU, 20.v.2010 (HNHM 99625); 1 km N of Kurbnesh, 41.7883°N, 20.1068°E, leg. ZE, ZF, JK, DM, 27.vi.2003 (HNHM 94833).

Distribution.

Lura-Dejë mountain group in northern Albania. Known only from two sites: the type locality at the southern foothills of the Mt. Lura in the gorge of the Varosh Stream, and the locality in the valley of the Urakë River, at the western foot of the Dejë. Although the elevation seems different, the record "Kurbnesh, 400 m" ( Dhora and Welter-Schultes 1999) most probably refers to the latter occurrence (Fig. 22).

Remarks.

In the gorge of the Varosh Stream this species occurs syntopically with Montenegrina skipetarica skipetarica .
