Montenegrina dofleini sinosi Pall-Gergely, 2010 Fig. 11N

Montenegrina dofleini sinosi Páll-Gergely, 2010: 150-152, figs 1-2. (genital anatomy, clausilium plate).

Diagnosis.

Shell medium, elongate. Lower and upper whorls strongly wrinkled or ribbed. Neck very weakly inflexed, behind the aperture densely striate-costate. Peristome ovoid. Lamella superior weak, does not overlap spiralis. In front view lamella inferior moderately emerged, subcolumellaris mostly hidden. Lunella dorsal-dorsolateral, weaker toward the basis. Basalis and subclaustralis mostly absent, residual sulcalis occasionally recognizable. Anterior plica superior absent or, if present, occasionally connected to the lunella complex.

Dimensions

(in mm). Hs: 13.9-16.3 (holotype 15.0), Ws: 3.4-3.7 (holotype 3.5 mm).

Type locality.

Greece, Western Macedonia, southern shore of the Prespa Lake, Agios Achillios, near the junction to Psarades, 850 m, 40.8105°N, 21.0702°E.

Type material.

Type locality, leg. Páll-Gergely, 25.v.2009, holotype (HNHM 97145), paratypes (HNHM 97146/3, SMF 333885/3, NMBE 28607/2, NHMW 107878/2); at the confluence of the Great and Small Prespa Lakes, leg. HS, 21.v.1986, paratypes [ prespaensis ] (NHMW 84022/3).

Other material.

Type locality, leg. ZE, ZF, JG, 28.vi.2013 (HNHM 99580); same locality, leg. ZF, EH, KJ, HS, 18.x.2014 (NHMW 110430/MN/0058).

Distribution.

The subspecies is known only from its type locality, which is only at 4 km distance from the nearest occurrence of Montenegrina dofleini prespaensis . Potentially suitable intermediate localities have not been searched, therefore it is not clear whether there are transitional populations between the two taxa (Fig. 14).

Remarks.

Morphologically Montenegrina dofleini sinosi might be an extremely ribbed morph of the closely related Montenegrina dofleini prespaensis . Its distinct subspecific status remains questionable until the finer distribution pattern and population genetic relationship of the two taxa becomes better known.
