Diagnosis.

Shell medium, light corneous. Lower whorls smooth to very densely striate, upper ones densely costate. Neck densely costate. Peristome angular, with swollen, reflexed margin. Lamellae superior and spiralis do not overlap. Subcolumellaris not or only barely, clausilium plate not at all visible through the aperture. Lunella lateral, fused to the basalis. Sulcalis absent or residual. Anterior plica superior separate from the lunella complex.

Distribution.

Originally this taxon was known only from the eastern coastline of the Ohrid Lake, between Ohrid and Gradište (see: Brandt 1962; Loosjes 1966). Recently it was also found in Central Albania, east of Bulqizë (Fig. 25). On the Mt. Temlishi it lives syntopically with Montenegrina nana barinai ssp. n.

Remarks.

First ochridensis was regarded by Nordsieck (1972) a subspecies of Montenegrina perstriata but later, pointing out the differences in shell morphology, he classified it as a distinct species ( Nordsieck 1988). More recently he again mentioned this taxon as Montenegrina perstriata ochridensis ( Nordsieck 2009).

In the original description the subgenus name Delima is likely a typographic error ( Wagner 1925: 70), because earlier and in the plate caption of the same paper he used Albanodelima ( Wagner 1924, 1925).
