Berlandina nakonechnyi Marusik et al., 2014a: 204 , figs 74‒82 (♂).

Material examined. MONGOLIA: Khovd Aimag: holotype ♂ ( ISEA) 33 km SW from Altai Village, Bodonchiyn- Gol River Valley , 45°46’17”N, 92°12’52”E, stony desert, 1300 m, 6–7.05.2012 (AF) ; paratype ♂ ( ISEA) 36 km SW from Altai Village, Bodonchiyn-Gol River Valley , 45°45’N, 92°11’E, stony desert, 1300 m, 7–8.05.2012 (AF) ; 1♀ 1♂ ( ISEA) 36 km SW from Altai Village, Bodonchiyn-Gol River Valley , 45°46’N, 92°12’E, stony desert, 1300 m, 17.05.2015 (AF).

Diagnosis. This species is most similar to B. yakovlevi Marusik et al., 2014 . The female of B. nakonechnyi can be separated from the former species by receptacles shifted anteriorly, much narrower septum and by the course of insemination ducts. Males of this species can be distinguished by the shape and proportions of embolus. B. nakonechnyi differs from B. yakovlevi by dark coloration of carapace and abdomen (cf. Fig. 5 and figs 90, 93 in Marusik et al. 2014a).

Description. Female. Total length 6.9. Carapace: 3.1 long, 2.4 wide. Coloration. Carapace dirty-yellow, with gray edges and two diverging stripes running from fovea and fringing cephalic area. Chelicerae brown. Sternum, labium and maxillae yellow. Legs dirty-yellow. Abdomen gray dorsally with pattern ( Fig. 5 ) and beige ventrally. Spinnerets yellow.

Receptacles round, located below atrium, separated by less than 1 diameter; margin of lateral pocket 3 times longer than diameter of receptacle. Distribution. Known from the type locality only.

Comments. This species was described based on two males, collected in almost one and the same locality. The newly collected material from the same locality contains both a male and a female. The single female obtained has a coloration very similar to that of the male of B. nakonechnyi , almost the same size and the epigyne resembling to that of B. yakovlevi , which is the sibling to B. nakonechnyi . Based on this we decided that this female belongs to B. nakonechnyi .
