Montenegrina perstriata mavrovoensis Nordsieck, 2009: 78, plate 3, fig. 11.

Diagnosis.

Shell medium, elongate, light corneous. Lower whorls nearly of the same width, almost smooth to finely, indistinctly costate. Upper whorls indistinctly wrinkled-costate. Neck costate. Peristome with simple margin. Lamellae superior and spiralis mostly overlap. Lamella subcolumellaris deep, even in oblique view barely visible. Lunella dorsolateral to lateral, not connected to the weak basalis. Subclaustralis residual, sulcalis present. Anterior plica superior absent or weak and separate from the lunella complex. Clausilium plate mostly not visible through the aperture.

Dimensions

(in mm). Hs: 15.4-18.4 (holotype 17.7), Ws: 3.9-4.5 (holotype 4.3).

Macedonia, Bistra Mts, Mavrovo 2 km towards Galičnik.

Type material.

Type locality, leg. H. Nordsieck, 4.viii.1974, holotype (SMNS 70545), paratypes (SMNS-N 6922/15, SMF320048/8).

Distribution.

Bistra Mts in western Macedonia. Known only from the type locality (Fig. 25).

Remarks.

Nordsieck (1977) noticed the peculiarity of this taxon and mentioned it as 'a morph standing close to subcristatula '. Later, in the description, he suggested that it is probably closer to Montenegrina perstriata diminuta ( Nordsieck 2009).
