Diagnosis. Fore wing length 5.4–7.1 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. Face strongly coriaceous and distinctly punctate, especially centrally. Clypeus strongly excised, with lobes rounded. Mesopleuron coriaceous and strongly punctate over almost entire surface. Mesoscutum coriaceous between dense punctures. Hind coxa with hind surface coriaceous and matt, smooth and shining only apically. Fore wing areolet closed, vein 3rs-m often partly unpigmented. Propodeum with only pleural and apical parts of lateral longitudinal carina present, coriaceous, more rugose on petiolar area. Female metasoma gradually tapered posterior to third segment. First tergite with median dorsal carinae present only basally, never surpassing middle of tergite, with numerous longitudinal wrinkles, especially on median part, 0.9–1.2 times as long as wide in females, 1.3 in males; second tergite basally with some short longitudinal wrinkles, 0.55–0.65 times as long as wide in females, 0.8–0.9 in males, second tergite 0.8–0.9 times length of 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 separated from yellow on clypeus, yellow on mouthparts, hind corner of pronotum, tegula, sometimes upper part of mesepimeron, scutellum at most with apical spot. Legs orange, all coxae orange, fore coxa dark basally, femora orange, hind tibia orange with apex dark, hind tarsus dark. Metasoma black.
