Figs 13 A–F, 14

Type material. Holotype ♀ ( MMUE), TAJIKISTAN: Vahdat District : Hissar Mt. Range, Ramit Reserve, 38°44’N, 69°18’E, 1324 m, 1.V.2015, leg. S.L. Zonstein.

Etymology. The specific epithet refers to the type locality of the new species.

Diagnosis. Female of the new species differs from that of B. hyrcanicus sp. n. by the lack of a dorsal abdominal scutum (vs. present), presence of two pairs of receptacles (vs. one pair), and converging glands of receptacles (vs. diverging).

Description. Female. Habitus as in Figs 13 A–C. Total length 2.18. Carapace 0.97 long, 0.78 wide. Eye sizes and interdistances: AME: 0.06, ALE: 0.06, PME: 0.06, PLE: 0.08, AME–AME: 0.03, PME–PME: 0.03. Carapace, sternum, labium, chelicerae and maxillae light reddish-brown. Legs yellowish-brown, without annulations. Abdomen grey dorsally, with distinctly lighter anterior part; venter light brown with grey marginal areas posteriorly. Spinnerets light brown, uniform in colour. Leg I measurements: 3.63 (0.93, 0.35, 0.96, 0.85, 0.54). Spination: I: Fe 2pl, Ti 14v, Mt 8v; II: Ti 10v, Mt 6v; IV: Fe 1d.

Epigyne as in Figs 13 D–F; fovea present, anterior margin distinct, copulatory openings closely spaced; two pairs of receptacles, duct connecting receptacles and receptacular glands visible through integument; both pairs of receptacles globular, primary receptacles located behind (in ventral view) copulatory openings, spaced from posterior margin of plate by one diameter, receptacles with small anterior and dorsal extension(s); secondary receptacles weakly sclerotized, connected to primary receptacles by wide ducts, ducts as long as length of receptacles; secondary receptacles separated by more than one diameter; thin, stick-like receptacular glands attached to duct near primary receptacles, glands converging; fertilization ducts located close to each other on meso-anterior part of primary receptacles, large, diverging.

Male. Unknown.

Comments. Generic placement is due to the ventral abdominal pattern, lack of large secondary receptacles, and pair of distinct hoods, characters shared with the type species.

Distribution. Known only from the type locality in Khatlon Region, southwestern Tajikistan ( Fig. 14 ).
