Description. FEMALE: Idiosomal length 305, maximum width 135. Gnathosoma ( Figs. 12 ) dorsally with 2 pairs of simple setae, ch 1 distinctly longer than ch 2. Dorsal medial apodeme well developed. Setae dFe needlelike. Idiosomal dorsum ( Fig. 11 ). All tergites punctate. Setae v 2 smooth, other dorsal setae barbed. Tips of setae sc 2, c 1, d, and e, blunt. Other dorsal setae pointed. Seate e with several large barbs. Length of dorsal setae: v 2 12, sc 2 45, c 1 48, c 2 68, d 39, e 26, f 72, h 1 69, h 2 57. Distances between dorsal setae: v 2- v 2 36, sc 2- sc 2 37, c 1– c 1 52, c 1– c 2 30, d–d 36, e–f 8, f–f 67, h 1– h 1 35, h 1– h 2 9. Idiosomal venter ( Fig. 12 ). Apodemes 1, 2, and sejugal apodeme well developed and joined with presternal apodeme. Secondary transverse apodeme present, not joined with apodemes 2. All ventral plates weakly punctate. Setae 1 a, 1 b, and 2 a strongly barbed, other ventral setae smooth. Posterior margin of posterior sternal plate convex. Setae ps 3 well separated from base of ps 2. Apodemes 3 weakly developed, diffuse. Apodemes 4 long, reaching level of setae 3 c. Apodemes 5 absent. Posterior margin of aggenital plate concave. Length of ventral setae: 1 a 30, 1 b 25, 2 a 30, 2 b 29, 3 a 31, 3 b 35, 3 c 25, 4 a 34, 4 b 37, 4 c 31, ps 1 12, ps 2 5, ps 3 11. Legs ( Figs. 13–15 ). Setation of legs as in B. latissimosetosa sp. nov. Leg I ( Fig. 13 ). Tibiotarsus with simple small claw situated on long pretarsus. Solenidia ω1 20> ω2 18> φ1 11 <φ2 12. Solenidion ω1 finger-shaped. Solenidion φ1 baculiform. Solenidia ω2 and φ2 uniformly thin. Seta dFeI hook-like, setae l’GeI blunt. Leg II ( Fig. 14 ). Tarsus with large padded claws. Solenidion ω (18) fingershaped. Solenidion φ small, difficult to see, setae d’FeII blunt. Leg III. Solenidion φ small, difficult to see, setae d’FeIII blunt. Leg IV ( Fig. 15 ). Tarsus short. Pretarsus short, with large simple claws and thin, tonguelike empodium distally. Setae v”TiIV, pl”TaIV blunt. Length of setae v”TiIV 23, pl”TaIV 20.

MALE and LARVA unknown.

Type material. Female holotype and 1 female paratype, UKRAINE, Crimea, “Cape Martyan” Nature Reserve, in soil under grass, 10 March 2010, coll. A. A. Khaustov.

Etymology. The species name refers to distribution of the new species on Cape Martyan.

Differential diagnosis. The new species is most similar to B. taurica Khaustov, 2008 . Both species have setae e with several strong barbs, subequal setae f and h 1 which much longer than e. The new species differs by position of setae ps 3 on distinct distance from base of setae ps 2 (in B. taurica setae ps 3 situated close to base of setae ps 2), by much shorter and smooth setae of posterior sternal plate (in B. taurica setae of posterior sternal plate distinctly longer and barbed).
