Diagnosis. Fore wing length 4.1–5.1 mm. Antenna in females with 16–18, in males with 16–20 flagellomeres. Face with punctures disappearing against the coriaceous background. Mesopleuron smooth and polished weakly punctate largely restricted to lower half. Propodeum with carinae largely reduced, at most with pleural and traces of lateral longitudinal carinae and with a change in sculpture around petiolar area. Tergite 1 1.15–1.3 times as long as wide in females, 1.2–1.8 in males, tergite 2 0.7–1.1 times as long as wide in both sexes; tergites 2 and 3 strongly coriaceous and matt, punctures indistinct, sculpture extending across the weak transverse impressions. Transverse impressions weak but distinct on tergites 1 and 2, at most present as a change in sculpture on tergite 3. Metasoma compressed posterior to third segment.

Colouration of females. Antenna dark brown, sometimes paler below. Head and mesosoma black, face with yellow along inner orbits, without yellow central face patch, yellow on clypeus and mouthparts, hind corner of pronotum, tegula, subtegular ridge, small to large shoulder mark, upper mesepimeron; scutellum at least with yellow tip, sometimes also with yellow sides, sometimes orange centrally. Legs orange, fore coxa yellow, mid coxa yellow or orange, hind coxa orange; femora orange, without black marks; hind tibia white with a dark apex, sometimes with a subbasal dark spot, hind tarsus dark, but first tarsomere basally white. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face, propleuron, epicnemium and a stripe on lower mesopleuron. Coxae and fore and mid legs often largely yellow.
