Bioblapsis polita ( Vollenhoven 1878, Trichomastix )

Bassus flavipes Holmgren 1858 (homonym)

Bassus tibialis Bridgman 1883 (homonym)

Diagnosis. Fore wing length 4.4 to 6.4 mm. Antenna in females with 16–18, in males with 17–20 flagellomeres, without tyloids. Face smooth and shining, with central area strongly protruding. Propodeum with spiracle enlarged, with rim pale; with a full set of carinae enclosing basal, lateral and petiolar areas, strongly rugose on petiolar area.

Colouration of females. Antenna black. Head and mesosoma black, face often with yellow central face patch, yellow on clypeus and mouthparts, hind corner of pronotum, tegula, usually subtegular ridge and upper mesepimeron; scutellum with two yellow anterolateral spots. Legs and all coxae orange; hind tibia orange or yellow, sometimes more whitish, with apex and dorsal side irregularly dark, hindtarsus dark, first and sometimes also other tarsomeres with a white or yellow base. Metasoma black or brown.

Colouration of males. As in females but with inner orbits broadly yellow and with central face patch large. Mesepimeron usually entirely yellow. Fore and mid coxae mostly yellow, hind tibia often whitish with apex dark and with a subbasal dark spot.
