Montenegrina apfelbecki wagneri Szekeres, 2006 in Erőss et al. 2006: 186-188, fig. 6.

Diagnosis.

Shell small, with whitish tint. All whorls smooth and glossy. Neck very weakly inflexed, behind the aperture finely striate. Basal and peripheral crests very weak. Peristome ovoid. Lamellae superior and spiralis do not overlap. In front view lamella inferior barely emerged. Deep subcolumellaris visible only in obliquely through the aperture. Lunella dorsolateral. Basalis mostly, subclaustralis always absent, sulcalis strong. Anterior plica superior usually absent or, if present, residual and connected to the lunella complex.

Dimensions

(in mm). Ws: 13.2-14.9 (holotype 14.9), Ws: 3.4-4.3 (holotype 4.2).

Type locality.

Albania, Mt. Thatë.

Type material.

"Mal i That", leg. Fuchs, holotype (NHMW 103375), paratypes (NHMW 47961/2).

Other material.

Albania, Korçë District, Mt. Thatë, E of Podgorije, ca. 1.3 km E of the Bregu i Stanit Summit, 1830 m, 40.8255°N, 20.8528°E, leg. ZB, CN, DP, 20.v.2007 (HNHM 99576); ca. 4.3 km NW of Liqenas, ca. 700 m south of a summit, 1910 m, 40.8183°N, 20.8728°E, leg. ZB, DP, 22.v.2007 (HNHM 99577); ca. 4.3 km NW of Liqenas, 400 m ESE of a summit, 1780 m, 40.8220°N, 20.8789°E, leg. ZB, CN, DP, 22.v.2007 (HNHM 99578); along the path from Goricë to the ridge, 40.8485°N, 20.8624°E, leg. ZB, CN, Schmotzer, 11.viii.2008 (HNHM 99579); near the 'Tower of the war’, alpine rocky grassland, 1750 m, 40.9122°N, 20.8498°E, leg. ID, 25.v.2013 (DED); same locality, 1810-1830 m, 40.9136°N, 20.8419°E, leg. ID, 24.ix.2013 (DED); Plaja e Pusit Summit, 2200 m, 40.8799°N, 20.8419°E, leg. ID, 25.vi.2013 (DED).

Distribution.

Alpine region (above 1700 m) of the Mt. Thatë in southern Albania. Dedov found this taxon syntopically with Montenegrina hiltrudae fusca Fehér & Szekeres, 2006 in the 'Tower of the war’ area, near the Albanian–Macedonian border (Fig. 14).

Remarks.

Due to misinterpretation of the label information, the original description erroneously indicated the type locality as "Maja e Madhe (1796 m), WNW of Peshkopi".

In Nordsieck’s view ( Nordsieck 2009) Montenegrina dofleini wagneri is synonymous with Montenegrina dofleini fagorum . However, in our opinion their distinct subspecies status is well supported by stable differences in shell morphology.
