Diagnosis. Fore wing length about 6.5 mm. Antenna in females with 18–19 flagellomeres, first flagellomere about 3.5 times longer than wide; in males with 19 to 20 flagellomeres and with narrow, long tyloids on flagellomeres 5/ 6 to 11. Face without a sulcus between compound eye and base of mandible, at most with a change in sculpture instead. Mesopleuron distinctly punctate over most of its surface. Propodeum with basal area more than 2.5 times wider than long, apical carina complete; petiolar area filled with carinulae. Tergite 2 rugose and matt over entire surface. Females with metasoma dorsoventrally depressed to apex.

Colouration of females. Antenna brown. Head and mesosoma black, yellow or orange on part of clypeus, mouthparts, hind corner of pronotum, tegula, and upper mesepimeron; with or without a small shoulder mark; scutellum black or with a yellow apical spot. Legs orange, coxae orange, femora orange; hind tibia white with a dark apex and a subbasal dark band, hind tarsus dark, first tarsomere white basally. Metasoma largely black but with hind margins of anterior tergites sometimes reddish.

Colouration of males. As in females but with yellow ventrally on scape and pedicel, antenna often orange below, yellow over entire face, propleuron, often large shoulder mark, varying portions of epicnemium and mesosternum, often lower mesopleuron; scutellum usually yellow. Fore and mid coxae usually yellow.
