Montenegrina tomorosi hunyadii ssp. n. Fig. 34J

Diagnosis.

Small subspecies with smooth whorls, inflexed neck, and well developed basal and peripheral crests.

Description.

The small, light corneous shell consists of 8½ to 9½ whorls. The surface is smooth, only at the neck is wrinkled-costate. The neck is inflexed, the basal and peripheral crests are well developed. The ovoid to somewhat angular peristome is attached, its margin is slightly swollen. The lamellae superior and spiralis usually do not overlap. In front view the lamella inferior is moderately emerged, the weakly-bent subcolumellaris is mostly not visible. The broad, dorsolateral lunella is fused, via the plica superior, to the plica principalis. The basalis is weak, not connected to the lunella. The subclaustralis is absent, the sulcalis is well developed. The anterior plica superior of variable strength is separate from the lunella complex. The clausilium plate is partly visible through the aperture.

Dimensions

(in mm). Holotype Hs: 12.1, Ws: 3.4, Ha: 3.2, Wa: 2.4; paratypes (HNHM 99511, n = 12): Hs: 10.8-13.1 (mean 12.2, S.D. 0.69), Ws: 3.0-3.6 (mean 3.3, S.D. 0.18), Ha: 2.8-3.5, Wa: 2.2-2.6.

Differential diagnosis.

Differs from all other Montenegrina tomorosi subspecies by its smaller, translucent shell, as well as the stronger neck inflection and crests.

Type locality.

Albania, Skrapar District, Tomorr Mts, ca. 1.5 km W of Terovë, dry gorge, 850 m, 40.7127°N, 20.1839°E.

Type material.

Type locality, leg. ZF, AH, TH, DM, 24.viii.2006, holotype (HNHM 99510), paratypes (HNHM 99511/97, NHMW 111232/5, HU/97, SZ/8).

Etymology.

The new taxon is named after András Hunyadi, malacologist, who accompanied the first author on several Balkan field trips, including the one that led to the discovery of this subspecies.

Distribution.

Tomorr Mts in southern Albania. Known only from the type locality, in the eastern slope of the Tomorr (Fig. 36).
