Diagnosis. Males may be easily identified according to the key (but see Bicellaria sp. 3 in “Unrecognized specimens” section); differences in genitalia of two allied species, B. sulcata and B. vana, are discussed under the latter species. The left phallic hook is long and broad, right one strongly reduced. Females may be identified according to characters given in the key.

Distribution. A broadly distributed West Palaearctic species. Record from East Siberia (Tuomikoski 1955) needs verification.

Remarks. Tuomikoski (1955) briefly redescribed this species, illustrated the hypandrium and synonymized it with his B. sulcata vanella. Collin (1961) provided a short redescription and illustrated the male genitalia. Chvála (1983) also redescribed this species, illustrated the face, antenna, hind leg, and genitalia, discussed the synonymy, and designated the lectotype.
