Description.

Female. Body length 1.60–2.05 mm; fore wing length 1.50–1.90 mm.

Coloration. Head and mesosoma green with diffuse metallic coppery luster, propodeum dorsally dark blue green with diffuse metallic coppery luster; antenna with scape, pedicel and anelli yellowish brown, F 1 – F 5 and clava brown, F 6 yellow. Fore and hind coxae dark green with diffuse metallic coppery luster, mid coxae yellowish brown, all femora yellowish brown, all tibiae and tarsi yellow. Fore wing with one spot near S, venation brown. Metasoma dorsally dark brown with metallic violet, green and coppery luster; ovipositor sheaths brown.

Sculpture. Head and mesosoma reticulate; clypeus striate-reticulate; scutellum, frenal area and propodeum reticulate, nucha finely reticulate; petiole smooth; metasoma smooth and shiny.

Head. Head in dorsal view 2.27–2.30 × as broad as long and 1.39–1.42 × as broad as mesoscutum; in frontal view 1.47–1.67 × as broad as high. POL 0.56–0.57 × as long as OOL. Eye height 1.09–1.21 × eye length and 1.38–1.65 × malar space. Distance between antennal toruli and lower margin of clypeus 2.70–3.00 × distance between antennal toruli and median ocellus. Antenna with scape 0.94–1.05 × as long as eye height and 1.14–1.15 × as long as eye length; pedicel 1.11–1.35 × as long as broad; combined length of pedicel and flagellum 0.78–0.80 × breadth of head; F 1 – F 6 longer than broad, F 1 1.78–2.10 × as long as broad and with 2–3 rows of sensilla; clava 1.71–2.26 × as long as broad, with small microsetose area on C 3 and C 4. Lower posterior corner of gena with sharp spine. Lower margin of clypeus concave bilaterally, in middle broadly emarginate.

Mesosoma. Mesosoma 1.19–1.20 × as long as broad. Scutellum moderately arched, 0.78–0.81 × as long as broad, frenal area differentiated by sculpture. Propodeum 0.59–0.70 × as long as scutellum, without costula but with median carina, nucha not small. Fore wing 1.93–2.14 × as long as its maximum width; basal cell partly setose, basal vein setose; speculum closed below; M 0.77–0.79 × as long as PM and 1.13–1.15 × as long as S, stigma small.

Metasoma. Metasoma 1.50–1.60 × as long as broad, 0.93–1.00 × as long as mesosoma, 0.77–0.79 × as long as mesosoma and head. Petiole 0.90–1.00 × as long as broad. Ovipositor sheaths projecting slightly beyond apex of metasoma.

Male. Body length 1.20 mm; fore wing length 1.15 mm. Head posterior to malar space striate reticulate. POL 0.75 × as long as OOL. Distance between antennal toruli and lower margin of clypeus 2.20 × distance between antennal toruli and median ocellus. Fore wing with M 1.25 × as long as S. Otherwise, similar to female.
