Montenegrina skipetarica gurelurensis ssp. n. Fig. 30O

Diagnosis.

Medium-size, strongly costate subspecies with detached peristome, dorsolateral lunella and often uninterrupted plica superior with long anterior part.

Description.

The shell is medium- to large-sized, light brownish-corneous, somewhat tumid, of its 9½ to 12½ whorls the lower three are almost of the same width. The surface is strongly costate, with denser ribs at the weakly inflexed neck. The basal crest is weak, the peripheral one is well visible. The light brown, ovoid peristome has simple, detached (rarely very narrowly attached) margin. The lamellae superior and spiralis overlap. The lamella inferior is emerged, well visible in front view. The broadly-bent lamella subcolumellaris is not visible in frontal, only in slanted view at the aperture. The lunella is dorsolateral, broad, mostly fused to the basalis that is as long as the subclaustralis. The sulcalis is week. The anterior part of the plica superior is long, ends in a lump behind the aperture, mostly does not reach the lunella complex. Part of the clausilium plate is visible through the aperture.

Dimensions

(in mm). Holotype Hs: 23.5, Ws: 5.4, Ha: 5.5, Wa: 4.2; paratypes Hs: 14.4-23.5 (mean 20.1, S.D. 2.36), Ws: 4.2-5.5 (mean 5.0, S.D. 0.39), Ha: 4.1-5.5, Wa: 3.2-4.3 (n = 12).

Differential diagnosis.

Distinguishable from Montenegrina skipetarica thysi Loosjes & Loosjes-van Bemmel, 1988 by the slender shell and deeper lunella, whereas from all other Montenegrina skipetarica subspecies by the costate shell and detached peristome.

Type locality.

Albania, Dibrë District, ca. 2 km W of Cidhnë along the footpath to Gurë-Lurë, gorge of the Përroi i Setës, 780 m, 41.7525°N, 20.2484°E.

Type material.

Type locality, leg. ZE, ZF, AH, DM, 12.iv.2006, holotype (HNHM 99459), paratypes (HNHM 99460/42+3aj, ER/42, HU/42, SZ/4); same locality, leg. ZE, DM, 10.x.2005, paratypes (HNHM 99461/24+7a+3aj, MMM-B01322/24, ER/24, SZ/6); 1.5-1.9 km W of Cidhnë, leg. ZE, ZF, JG, 1.vii.2015, paratypes (HNHM 99462/45, NHMW 111208/34+26a+12aj, GR/70).

Other material.

Albania, Dibrë District, ca. 1.5 km W of Cidhnë, 41.7528°N, 20.2505°E, leg. ZE, ZF, AH, DM, 12.iv.2006 (HNHM 99463).

Etymology.

The new taxon is named after the village Gurë-Lurë, as the type locality is along the footpath leading there.

Distribution.

Southern part of the Lura Mountain in northern Albania. This taxon is known only from the Setë Gorge, where it was found at a short section of the footpath between Cidhnë and Gurë-Lurë. Towards Cidhnë, at ca. 1.5 km from the hydroelectric station, there is a narrow contact zone between this taxon and Montenegrina skipetarica puskasi , and to the east of that zone only Montenegrina skipetarica puskasi could be found (Fig. 31B).
