Diagnosis. Fore wing length 3.4–4.1 mm. Antenna of both sexes with 17–19 flagellomeres. Mesoscutum smooth between irregular, rather weak punctures which are often denser towards anterior margin. Mesopleuron smooth and shining, at most with some weak punctures along anterior margin and very restricted coriaceous areas. Propodeum with a full set of strong carinae enclosing basal, lateral and petiolar areas, the areas with rugose sculpture. Tergite 2 0.8–1.1 times as long as wide. Metasoma in females dorsoventrally depressed, tapered towards apex.

Colouration of females. Antenna black or dark brown. Head and mesosoma black, face with yellow inner orbits which are sometimes restricted to frons, yellow or brown on clypeus and mouthparts, yellow on hind corner of pronotum, tegula, shoulder mark, and sometimes upper mesepimeron; scutellum black. Legs mainly orange or brown, coxae and trochanters black; femora extensively dark basally, hind femur often all dark; hind tibia and tarsus yellow or light brown, tibia sometimes with dark apex and a weak subbasal mark. Metasoma black, often with orange apical bands on tergites 2 to 4 or 5.
