The caspica group

Diagnosis. Members of this group can be recognized by (1) the claw like outgrowth below embolus, (2) the almost straight diagonal course of seminal duct, (3) the short and wide embolus starting from 9–10 o’clock, and (4) the wide semicircular epigynal fovea lacking septum.

Composition. We place two species in this group: B. apscheronica Dunin, 1984 and B. caspica Ponomarev, 1979 . It is very likely that these two species are synonyms.
