Montenegrina rugilabris golikutensis View in CoL ssp. n. Fig. 28B

Diagnosis.

Medium-size, light to darker purplish-brown subspecies with smooth whorls, not overlapping lamellae superior and spiralis, in front view not visible lamella subcolumellaris, and mostly separate anterior plica superior and lunella complex.

Description.

The medium-size, dark to lighter purplish-brown shell consists of 9 to 10 whorls, which are separated by a whitish suture. The entire surface is smooth, except that of the weakly inflexed, very finely and densely costate neck. The basal and peripheral crests are weak. The light brown, ovoid to somewhat quadrangular, narrowly attached peristome has slightly swollen margin. The lamella superior initiates at the end of the spiralis, without overlap. The lamella inferior is moderately emerged, its end part descends straight. The broadly bent subcolumellaris is not visible in front view. The dorsal to dorsolateral lunella is short and wide, fused to the short subclaustralis but not to the much longer basalis. The sulcalis is strong. The anterior par of the plica superior is long, often connected to the lunella complex. The clausilium plate is partly visible through the aperture.

Dimensions

(in mm). Holotype Hs: 17.6, Ws: 4.7, Ha: 4.3, Wa: 3.5; paratypes Hs: 16.2-20.1 (mean 18.3, S.D. 1.17), Ws: 4.6-5.8 (mean 5.0, S.D. 0.33), Ha: 4.3-5.3, Wa: 3.3-4.2 (NHMW 111215, n = 12).

Differential diagnosis.

Differs from Montenegrina rugilabris irmengardis and Montenegrina rugilabris lambdaformis Reischütz & Sattmann, 1990 by the non-overlapping lamellae superior and spiralis, deeper lunella, and the separate basalis, whereas from all other Montenegrina rugilabris subspecies by its purplish-brown shell surface.
