Campocraspedon caudatus ( Thomson 1890, Homotropus )

Diagnosis. Fore wing length 4.5–5.5 mm. Antenna in females with 17, rarely with 18, in males with 17–18 flagellomeres. Female face black, male face entirely yellow or with a median vertical black line. Propodeum with carinae weak, pleural and lateral longitudinal carinae usually present, transverse carina and median longitudinal carinae usually absent but indicated by some weak rugae; petiolar area coriaceous and rugose.

Colouration of females. Antenna black, paler below. Head and mesosoma black, face black, yellow on clypeus, mouthparts often more orange, yellow on hind corner of pronotum, tegula, and often upper mesepimeron; scutellum black, at most with a light brown mark on extreme apex. Legs orange, coxae black; femora orange; hind tibia orange with apex and tarsomeres dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, subtegular ridge, often most of mesosternum and a stripe on lower mesopleuron; face entirely yellow but often with a black median stripe which arises below antennal sockets. Fore and mid coxae often largely yellow. Tergites 2 to 4 often with yellow markings along hind margin.
