Diagnosis.

Shell small to medium, smooth to strongly wrinkled-costate. Neck weakly inflexed to inflexed, basal and peripheral crests well recognizable. In front view lamella inferior moderately emerged, medium-bent subcolumellaris not or only barely visible. Lunella dorsolateral to lateral, mostly fused to the basalis. Subclaustralis and sulcalis present. Anterior plica superior absent or weak. Clausilium plate not or barely visible through the aperture.

Remarks.

Montenegrina nana , which was formerly classified as a subspecies of Montenegrina perstriata , differs from this species by its smaller size, oblique peristome, and deeper inflexed neck. One of the subspecies, Montenegrina nana barinai ssp. n., occurs syntopically and does not hybridize with Montenegrina perstriata ochridensis , indicating that they are distinct species.
