Homotropus similis Lange 1911

Diagnosis. Fore wing length 4.6–6.6 mm. Antenna in females with 17–19 flagellomeres, in males with 18–19 flagellomeres, with tyloids on flagellomeres 2 to 10/12. Epicnemial carina often only weakly interrupted behind fore coxa. Mesoscutum strongly coriaceous and distinctly punctate. Propodeum almost devoid of carinae, at most with pleural carina and apex of lateral longitudinal carina weakly indicated, sculpture coriaceous and matt. Female metasoma gradually tapered to apex, first tergite 1.0–1.2 times longer than wide in females, 1.2–1.3 in males; spiracle of third tergite either on or above lateral fold.

Colouration of females. Antenna dark brown. Head and mesosoma black, face with a yellow central face patch, yellow on clypeus, mouthparts, tegula, large shoulder mark, upper mesepimeron, and often hind corner of pronotum and subtegular ridge; scutellum yellow along sides and apex. Legs orange, all coxae and trochanters black or brown; femora orange, often marked with black ventro-basally; hind tibia yellow or orange with a dark apex, tarsus dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face, usually entire propleuron, epicnemium, mesosternum and lower mesopleuron. All coxae yellow, hind coxa sometimes marked with black basally. Metasoma black with large yellow spots on anterolateral corners of tergites 3 and sometimes 4.
