Diagnosis. Fore wing length 3.9–5.3 mm. Antenna with 22–24 flagellomeres in both sexes, first flagellomere 5 to 5.9 times longer than wide; in males with narrow, long tyloids on flagellomeres 7 to 10/11. Face without a sulcus between compound eye and base of mandible, at most with a change in sculpture instead. Mesopleuron with punctures weak, distinct at most on lower half. Propodeum with basal area 1.5 times wider than to as wide as long, enclosed by strong carinae; petiolar area mostly smooth, with some irregular wrinkles close to its margins. Tergite 2 with longitudinal wrinkles basally, remainder smooth and shining. Females with metasoma slightly laterally compressed and tapered apically.

Colouration of females. Antenna orange or brown to black. Head and mesosoma black, face with or without yellow central face patch, yellow on mouthparts, hind corner of pronotum, tegula, usually subtegular ridge, and upper mesepimeron; without yellow shoulder marks; scutellum black. Legs orange, coxae yellow; femora orange; hind tibia and tarsus orange or brown. Metasoma orange on tergites 2 to 4, 5 or 6, often dark basally on tergite 2 and on median part of tergites.

Colouration of males. As in females but with yellow ventrally on antenna and entire face. Metasoma as in females, but tergites often dark medially.
