Montenegrina dedovi dedovi Nordsieck, 2009: 75-77, plate 2, fig. 4. - Dedov and Neubert 2009: 92, plate 1, fig. 5.

Diagnosis.

Shell small to medium, light corneous. All whorls smooth. Neck weakly inflexed, finely and densely striate. Basal and peripheral crests weak. Peristome, ovoid to somewhat angular, with simple margin. Lamellae superior and spiralis do not overlap. Subcolumellar lamella not or barely, clausilium plate not at all visible through the aperture. Lunella lateral. Subclaustralis short to residual, sulcalis very weak or absent. Anterior plica superior distant and diverging from the plica principalis, not connected to the lunella complex.

Remarks.

Originally Montenegrina laxa dedovi was described as a separate species (Nordsieck 2008), but its shell structure (and particularly its palatal plicae) positions it among the subspecies of Montenegrina laxa .
