Diagnosis. Fore wing length 3.8–5.9 mm. Antenna in females with 20–22 flagellomeres, with multiporous plate sensilla present also ventrally on apical flagellomeres, without conspicuous velvety areas; in males with 20–23 flagellomeres, with uni-coloured tyloids on flagellomeres 6 / 7 to 11 / 12. Face entirely coriaceous, with punctures indistinct. Mesoscutum smooth and shining, with distinct and evenly distributed punctures. Mesopleuron smooth and shining on upper half and distinctly punctate on lower half. Hind coxa with outer hind surface mostly smooth and shining, without any sculpture apart from around seta roots. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas, the areas with rugose to coriaceous sculpture, but petiolar area often with large smooth areas. Metasoma evenly tapered towards apex, first tergite 1.0– 1.2 times longer than wide in females, 1.4–1.5 in males.

Colouration of females. Antenna black or dark brown. Head and mesosoma black, face usually with a yellow central face patch, clypeus black, yellow on mouthparts, hind corner of pronotum, tegula, subtegular ridge, upper mesepimeron; without yellow shoulder marks, scutellum black. Legs orange, fore and mid coxae black with yellow apices, their trochanters yellow, hind coxa and trochanter black; femora orange; hind tibia orange with a dark apex, tarsus dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on antenna, entire face, propleuron, epicnemium, large part of pronotum and mesosternum, and large shoulder mark. Fore and mid coxae and trochanters yellow, hind coxa with a yellow apex, at most hind trochanter black-marked. Metasoma black, with yellow spots on anterolateral corners of tergites 3 and often 4.
