Montenegrina skipetarica danyii ssp. n. Fig. 30N

Diagnosis.

Small, slender subspecies with costate apical whorls and neck, overlapping lamellae superior and spiralis, and in front view mostly visible lamella subcolumellaris.

Description.

The small, slender, light brownish-corneous shell consists of 10 to 11½ whorls. The lower whorls are smooth, the upper ones are increasingly costate toward the tip. The weakly inflexed neck is densely costate. The basal crest is weak, the peripheral one is well visible. The ovoid to somewhat quadrangular peristome is broadly attached, its margin is somewhat swollen. The lamella superior is long, its frontal half is of even height. Inward it overlaps with the lamella spiralis. The moderately emerged lamella inferior ends with a straight descent. The broadly-bent lamella subcolumellaris is mostly visible in front view. The inner end of the plica principalis is often fused to the superior. The dorsolateral lunella is short and broad, it is mostly connected to the plica basalis. The basalis and subclaustralis are of the same length. The sulcalis is week. The anterior part of the plica superior is weak, separate from the lunella complex, occasionally absent. The clausilium plate is only barely visible through the aperture.

Dimensions

(in mm). Holotype Hs: 16.2, Ws: 4.1, Ha: 3.6, Wa: 3.0; paratypes Hs: 13.1-16.2 (mean 14.7, S.D. 0.77), Ws: 3.5-4.1 (mean 3.8, S.D. 0.24), Ha: 2.9-3.7, Wa: 2.4-3.0 (HNHM 99472, n = 12).

Differential diagnosis.

The new subspecies can be distinguished from Montenegrina skipetarica pifkoi ssp. n. by its more slender shell and overlapping lamellae superior and spiralis, whereas from all other Montenegrina skipetarica subspecies by its considerably smaller size.

Type locality.

Albania, Dibrë District, 9 km N of Cidhnë along the road from Cidhnë to Fushë-Lurë, 1330 m, 41.8149°N, 20.2775°E.

Type material.

Type locality, leg. TD, ZE, ZF, DM, 10.x.2005, holotype (HNHM 99471), paratypes (HNHM 99472/48, MMM-B01323/49, ER/49, SZ/4); type locality, leg. LD, ZE, ZF, AH, DM, 29.vi.2007, paratypes (HNHM 99473/64, NHMW 111210/2+1a, ER/69, HU/69, SZ/3).

Etymology.

The new taxon is named after László Dányi, entomologist and pedozoologist (HNHM), who was the companion to the first author on several Balkan field trips, including the one during which this subspecies was collected.

Distribution.

Eastern part of the Lura Mountain in northern Albania. Known only from the type locality (Fig. 31B).
