Diagnosis.
Shell small to medium, elongate. In front view lamella inferior weakly emerged. Lunella dorsolateral. Sulcalis present. Anterior plica superior mostly absent. Clausilium plate partly visible through the aperture.
Dimensions
(in mm). Hs: 13.9-15.6 (holotype 13.9), Ws: 3.4-4.4 mm (holotype 3.4) (see type and other material).
Type locality.
"Theth valley" = Albania, Prokletije Mts, one of the mountains surrounding the Theth Valley (probably Mt. Jezercë).
Type material.
"Theth valley", ex Nádai, ex Holzinger, collected by an unknown mountaineer, vii.1996, holotype (HNHM 94839).
Other material.
Albania, Malesia District, above the N side of the Qafa e Valbonës, along the footpath between Rragam and Theth, 1850 m, 42.4068°N, 19.8122°E, leg. TD, ZE, ZF, DM, 06.x.2005 (HNHM 99613); same locality, leg. Ádám, GP, Somay, 5.ix.2005 (HNHM 99614).
Distribution.
In the central part of the Prokletije Mts in northern Albania.
The description of this subspecies was based on a single shell without precise locality and collector information. Accordingly, type locality was defined only as "Maja e Jezerces region" ( Erőss et al. 2006). Recently the subspecies has been re-discovered near the Valbona Pass (Qafa e Valbonës), south of the Jezercë Summit. Notably, along the Theth to Rragam footpath that crosses the main mountain ridge, Montenegrina okolensis okolensis could be found only around its highest point, near to and above the pass, between 1760 and 1850 m (see also: Fehér and Erőss 2009) (Fig. 26).
Remarks.
Nordsieck (2009) considered okolensis a synonym of caesia Fehér & Szekeres, 2006. New okolensis samples confirm the stability of its morphological differences from caesia , namely the elongate shell, deeper lunella and better developed sulcalis. Therefore we maintain it as a distinct subspecies.
