Diagnosis.
Shell medium, light violet-brown with whitish tint. Whorls flattened, smooth, only weakly inflexed neck costate. Basal and peripheral crests weak. Peristome broadly attached, ovoid, with somewhat swollen margin. Lamellae superior and spiralis do not overlap. In front view lamella inferior moderately emerged, medium-bent subcolumellaris hidden. Lunella dorsolateral, fused to the short basalis. Subclaustralis also short, sulcalis residual. Anterior plica superior mostly absent, if present short and separate from the lunella complex. Clausilium plate almost entirely visible through the aperture.
Dimensions
(in mm). Hs: 16.1-18.0 (holotype 18.0), Ws: 4.2-4.6 (holotype 4.5).
Type locality.
Albania, Tiranë District, N slope of Mt. Dajti, 1600 m.
Type material.
Type locality, ex Edlauer, paratypes (NHMW 75000/-E 16652/4); Mal i Dajtit, N-slope, 100 m beneath the summit, ex Edlauer, paratypes (NHMW 75000/-E 32343/4). The holotype (NHMW 76600) could not be found in the NHMW collection.
Distribution.
This taxon is known from the summit region of the Mt. Dajti (1613 m), east of Tiranë (Fig. 12).
Remarks.
The type material is from the collection of Edlauer and, according to the label information, it has been determined as weigneri by Käufel. Therefore, it could have been collected in the 1930s, possibly by Fuchs or Bischoff. Although the type locality seems to be limited to the summit region of the Mt. Dajti, we were unable to find this species there.
