Diagnosis. Bicellaria spuria may be identified according to the key; however, there are several other very similar (still undescribed), species and some will be described elsewhere (see also “Unidentified specimens” section). The main differential characters are as follows: prescutellar part of mesoscutum equally dark as the rest of mesoscutum, usually at most 9 setae in posthumeral and intrahumeral area, body entirely black setose, fore tibia with elongated posteroventral setae, face medium wide (about as 2–3 facets), only left phallic hook long and simply bowed, right one reduced, and hypandrium with narrow and apically straight processes. Because of uncertainty of identification of females, records based solely on females are omitted here.

Distribution. West Palaearctic species. Melander (1965) recorded this species from North America, but this record remains doubtful as well as a record from the Oriental Region [ B. spuria?: Bezzi (1912) ].

Remarks. Tuomikoski (1955) provided a short redescription, and illustration of the hypandrium. Collin (1961) also provided a short redescription, with notes on synonymy. Chvála (1983) again redescribed this species, provided a habitus figure, and illustrations of the mouthparts, face, antenna, fore tibia, hind leg, and genitalia, and examined the synonymy.
