Syrphophilus stibarus Momoi 1973

Syrphophilus dilleriator Aubert 1976

Diagnosis. Fore wing length 4.2–5.5 mm. Antenna in females with 16–17 flagellomeres, in males with 17–19 flagellomeres. Mesoscutum smooth and shining between weak to strong punctures. Mesopleuron smooth and shining between strong punctures which are separated by less than their diameter. Sternaulus weakly to strongly impressed. Propodeum with a full set of strong carinae enclosing basal, lateral and petiolar areas, the areas with rugose sculpture. First tergite with median dorsal carinae at most weakly indicated on part of tergite. Second and third metasomal tergites very strongly punctate against a smooth and polished background.

Colouration of females. Antenna black or brown. Head and mesosoma black, face with yellow inner orbits and often yellow central face patch, yellow on clypeus, mouthparts, hind corner of pronotum, tegula, sometimes subtegular ridge, small to large shoulder mark, and often upper mesepimeron; scutellum partly yellow, at least with yellow apex. Legs orange, coxae and all trochanters black, fore and sometimes mid coxae often with yellow apex; femora orange, marked with black below, sometimes hind femur all dark; hind tibia orange with apex or dorsal side dark, hind tarsus dark. Metasoma orange on tergites 2 to 3 or 4 but sometimes dark and only with orange or yellow posterior bands on tergites 2 to 3.

Colouration of males. As in females but with yellow ventrally on scape, pedicel and sometimes entire antenna, face entirely yellow or with yellow inner orbits and a central yellow spot, and yellow on parts of epicnemium. Fore and mid coxae and their trochanters usually entirely yellow, hind coxa black with a yellow apex. Metasoma as in females but often tergites 2 and 3 black basally.
