Montenegrina skipetarica pifkoi ssp. n. Fig. 30L

Diagnosis.

Small subspecies with indistinctly costate apical whorls, wrinkled neck, non-overlapping lamellae superior and spiralis, and frontally visible lamella subcolumellaris.

Description.

The small, light brownish-corneous shell consists of 9 to 11½ whorls. The lower whorls are smooth, the upper ones are indistinctly wrinkled-costate. The weakly inflexed neck is strongly, irregularly wrinkled. The basal crest is weak, the peripheral one is well recognizable. The ovoid to somewhat quadrangular peristome is broadly attached, its narrow margin is somewhat swollen. The lamella superior initiates at the depth where the spiralis ends, without overlap. The moderately emerged terminal part of the lamella inferior descends in a straight line. In front view the broadly-bent lamella subcolumellaris is mostly well visible. The inner end of the plica principalis is often fused to the superior. The dorsolateral lunella is short and broad, it is connected to the similarly short plica basalis. The basalis and subclaustralis are of the same length. The sulcalis is week. The anterior part of the plica superior is separate from the lunella complex. The clausilium plate is partly visible through the aperture.

Dimensions

(in mm). Holotype Hs: 15.4, Ws: 4.2, Ha: 3.7, Wa: 2.9; paratypes Hs: 13.2-17.1 (mean 15.4, S.D. 1.24), Ws: 3.7-4.4 (mean 4.0, S.D. 0.21), Ha: 3.4-4.0, Wa: 2.6-3.2 (HNHM 99465, n = 12).

Differential diagnosis.

Differs from Montenegrina skipetarica danyii ssp. n. by the stouter shell and non-overlapping lamellae superior and spiralis, from Montenegrina skipetarica pindica by the separate anterior plica superor, whereas from all other Montenegrina skipetarica subspecies by the much smaller shell size.

Etymology.

The new taxon is named after Dániel Pifkó, botanist (HNHM), who collected invaluable zoological material during his field trips in Albania.

Distribution.

Mt. Dejë in northern Albania. This taxon was found at the western slope along the climbing path from Macukull village to the Dejë Summit, between 1250 and 2000 m (Fig. 31B).
