Diagnosis. Fore wing length 3.6–4.5 mm. Antenna of both sexes with 20 to 21 flagellomeres, apical flagellomeres with multiporous plate sensilla also present ventrally; in males with narrow, long tyloids on flagellomeres 7 to 14 / 15. Face evenly coriaceous, punctures disappearing against the background sculpture. Clypeus weakly excised, with lobes rounded. Mesopleuron strongly coriaceous on lower half and front part of upper half, with very weak or no punctures. Mesoscutum strongly coriaceous, very weakly punctate. Hind coxa with hind surface coriaceous and matt. Fore wing areolet closed, vein 3 rs-m usually unpigmented, rarely areolet open. Propodeum with only pleural carina and apical parts of longitudinal carinae present, evenly coriaceous, smoother on petiolar area. Female metasoma dorsoventrally depressed. First tergite without median dorsal carinae but sometimes with strong longitudinal wrinkles, 1.3–1.7 times as long as wide; second tergite basally with strong longitudinal wrinkles, 0.7–0.8 times as long as wide in females, 0.8–1.1 in males, second tergite 0.9 –1.0 times as long as first tergite; spiracle of third tergite on dorsal part, above lateral fold.

Colouration of females. Antenna black. Head and mesosoma black, sometimes with a yellow central face patch which is always separated from yellow on clypeus, yellow on mouthparts, hind corner of pronotum, tegula, subtegular ridge, large shoulder mark often with inner corners recurved on mesoscutum, mesepimeron, most of scutellum. Legs yellow or orange, either all coxae orange or black, fore and mid coxae with yellow apices, femora orange, hind tibia orange with apex dark, hind tarsus dark. Metasoma black, tergites 2–4 all or mainly orange.

Colouration of males. As in females but additionally with yellow over entire face, scape and pedicel and usually antenna ventrally, propleuron, epicnemium, mesosternum and a stripe on lower mesopleuron, fore and mid coxae; hind tibia often paler than in female, sometimes mainly yellow or white with apex and usually outer surface dark. Metasoma black, often irregularly orange on tergites 2–4, and often basal yellow spots on tergites 3 and 4.
