Diagnosis. Bicellaria nigrita may be, as are all three European species of the B. nigra complex, easily identified in males according to the genitalia. Postgonites are shortened, both phallic hooks present and longer than the postgonites. Moreover, males have a black setose body which differentiate it from both other species of this complex. However, identification of females may be difficult, differing by characters given in the key; however, the variation range of these characters remains unknown.

Distribution. Temperate and southern Europe from Great Britain to central European Russia, south to Bulgaria and Greece.

Remarks. Tuomikoski (1955) provided a short redescription and illustration of the hypandrium. Collin (1961) briefly redescribed this species and provided an illustration of the genitalia. Chvála (1983) redescribed this species and provided illustrations of the face, antenna, mid tibia, hind leg, and genitalia.
