Diagnosis. The species is a member of the B. austriaca complex (see under this species). Males of all four species of this complex ( B. italica , B. austriaca , B. intermedia , B. collini ) may be easily identified according to the key due to different genitalia. Males of B. intermedia may be easily recognized according to two long and narrow, irregularly bent phallic hooks [accurately illustrated by both Collin (1961) and Chvála (1983)]. We found no reliable character enabling to differentiate females from B. italica .

Distribution. Eurosiberian species.

Remarks. The species was originally described from many localities in Denmark. Tuomikoski (1955) provided a short redescription and illustration of the hypandrium. Collin (1961) provided a short redescription and illustrations of the hind leg, head, antenna and genitalia, in addition to notes to its identity (comparison with type specimens). Chvála (1983) also redescribed this species, provided illustrations of the face, antenna, hind leg, genitalia (incl. variations in the shape of hypandrium), and designated a lectotype.
