Montenegrina perstriata tenebrosa Nordsieck, 2009 View in CoL Fig. 27M
Montenegrina perstriata - Dhora and Welter-Schultes 1999: 16.
Montenegrina perstriata tenebrosa Nordsieck, 2009: 78-79, plate 3, fig. 14.
Diagnosis.
Shell medium to large, dark corneous. Lower whorls smooth, upper ones very finely and densely striate. Neck densely striate. Peristome rounded to angular, with strongly swollen, reflexed margin. Lamellae superior and spiralis mostly do not overlap. Subcolumellaris mostly not, clausilium plate not visible through the aperture. Lunella dosolateral-lateral, fused to the basalis. Sulcalis well developed. Anterior plica superior frequently connected to the lunella complex.
Dimensions
(in mm). Hs: 18.3-21.4 (holotype 20.9), Ws: 4.75-5.6 (holotype 5.3).
Type locality.
Albania, Mali i Gurit, Qafa e Zylit, 1800 m.
Type material.
Type locality, leg. Dhora, 16.ix.1996, holotype (SMNS 70546), paratypes (SMNS-N 10698/4, SMF 328780/3).
Other material.
Albania, Bulqizë District, Maja a Zyllit (= Maja e Shullanit), 6 km from the Librazhd to Peshkopi road toward Sebisht, 1360 m, 41.3611°N, 20.3967°E, leg. ZF, 13.iv.2014 (HNHM 98975).
Distribution.
Gollobordë Plateau in northeastern Albania. The precise location of the type locality is unknown, but the material from the road to Sebisht is thought to be from its vicinity (Fig. 25).
Remarks.
Nordsieck (2009) noted that Montenegrina perstriata tenebrosa is close to the ‘crassa’ mentioned by Fehér and Erőss (2009) from central Albania. Based on a large set of recently obtained samlpes we are of the opinion that the form mentined as crassa ( Fehér and Erőss 2009) belongs to Montenegrina perstriata callistoma . We regard Montenegrina perstriata tenebrosa an extremely large member of this heterogeneous group, but maintain its status as a separate subspecies.
