Diagnosis. The species may be easily identified according to the key. Males have typically S-shaped and apically bent left phallic hook (right one reduced), slightly asymmetrical postgonites (right one slightly broader than left) and relatively short and broad, apically slightly diverging and short setose hypandrial processes. Moreover, it differs from similar species ( B. spuria , B. mera ) by paler prescutellar depression in both sexes, broader face and longer anteroventral setae on mid femur and ventral setae on hind tibia. We found a single male specimen with one dorsal seta on base of left third antennal segment.

Distribution. West Palaearctic species, distributed in Europe from Andorra , Italy, Bulgaria and Greece in the south up to the extreme north of Scandinavia.

Remarks. Tuomikoski (1955) provided a short redescription and illustration of the hypandrium. Collin (1961) also included a short redescription, and illustrations of the hind leg and genitalia (however, phallic hook on his fig.

91a appears as in B. vana not showing typical strong curves). Chvála (1983) also redescribed this species and provided illustrations of the face, antenna, hind leg, and male genitalia.
