Taxon classification Animalia Stylommatophora Clausiliidae
Montenegrina sturanyana sturanyana
ssp. n.
Fig. 34K
Diagnosis
.
Small subspecies with non-overlapping lamellae superior and spiralis, deep-ending subcolumellaris, missing basalis and anterior plica superior.
Description.
The small, light corneous shell is comprised of
91/2
to 10 whorls, of which the last three are of nearly the same width. The weakly inflexed neck is finely striate, otherwise the entire shell surface is smooth. The basal crest is weak, the peripheral one is not recognizable. The ovoid peristome is attached, its margin is wide and swollen. The lamellae superior and spiralis do not overlap. In front view the straight descending end of the lamella inferior is moderately emerged, the medium-bent subcolumellaris is not visible. The lunella is broad, dorsolateral-lateral. The plica superior occasionally reaches farther forward than its fusion with the lunella. Of the lower plicae the basalis is absent, the subclaustralis is residual, the sulcalis is well developed. The anterior plica superior is missing. The clausilium plate is not visible through the aperture.

Differential diagnosis.
The new taxon differs from
Montenegrina sturanyana gropana
by its less elongate shell and the absence of the basalis, from
Montenegrina sturanyana ostrovicensis
by its deeper lunella, and from both subspecies by its finer neck sculpture, non-overlapping lamellae superior and spiralis, and missing anterior plica superior.

Etymology.
The new species is dedicated to Rudolf Sturany (1867-1935), Austrian zoologist, former curator of the Mollusc Collection at NHMW, in appreciation of his pioneering contribution to the research of the Balkan fauna.
Distribution.
Western side of the Jablanica Mts in central eastern Albania. Known from two nearby localities (Fig. 33).
