Montenegrina sturanyana sp. n.

Diagnosis.

Shell small, glossy, light corneous. All whorls smooth. Neck weakly inflexed, striate to striate-costate. Basal crest weak to well developed, peripheral crest absent to recognizable. Peristome attached, ovoid to somewhat angular, its margin wide and swollen. In front view lamella inferior is weakly emerged, medium-bent subcolumellaris hidden or only barely visible. Lunella broad, dorsolateral to dorsolateral-lateral. Plica superior often fused to the principalis and can reach farther forward than its contact with the lunella. Basalis absent to short and separate from the lunella. Sub claustralis absent to residual, sulcalis of variable strength. Anterior plica superior absent or weak and not fused to the lunella complex. The clausilium plate is not or only barely visible through the aperture. Differs from Montenegrina tomorosi Brandt, 1961 by its slender stature, stronger basal crest, deeper lamella subcolumellaris and weaker subclaustralis, and from all other Montenegrina species by the combination of the dorsolateral to lateral lunella and strongly reduced basal plicae.
