Female. Body length 1.50–1.55 mm; fore wing length 1.43–1.50 mm.

Coloration. Head black in dorsal view and dark blue-green with metallic diffuse luster in frontal view; antenna with scape yellowish brown; pedicel, anelli, F 1 – F 6, and clava brown. Mesosoma black, but propodeum dorsally dark blue-green with metallic diffuse luster; fore and mid coxa black, hind coxae basally black, apically yellowish brown, all femora yellowish brown, all tibiae and tarsi yellow. Fore wing hyaline, venation yellowish brown. Metasoma dark brown with metallic green, diffuse coppery luster; ovipositor sheaths dark brown.

Sculpture. Head finely reticulate; clypeus radially striate, but near clypeal margin smooth. Mesosoma finely reticulate; propodeum weakly alutaceous. Metasoma Mt 2 and Mt 3 smooth, Mt 4 – Mt 8 weakly alutaceous and shiny.

Head. Head in dorsal view 2.30–2.36 × as broad as long and 1.31–1.33 × as broad as mesoscutum; in frontal view 0.90–1.11 × as broad as high. Vertex with one continuous crest composed of small sharp teeth, crest height 0.50 × eye length. POL 0.85–0.87 × as long as OOL. Eye height 1.37–1.40 × eye length and 1.95–2.10 × as long as malar space. Distance between antennal toruli and lower margin of clypeus 4.40–4.15 × distance between antennal toruli and median ocellus. Antenna with scape 1.09–1.12 × as long as eye height and 1.44–1.53 × as long as eye length; pedicel 1.35–1.45 × as long as broad; combined length of pedicel and flagellum 0.95–0.98 × breadth of head; F 1 – F 6 longer than broad, with 1 row of sensilla; clava 3.70–3.84 × as long as broad, with small micropilose areas on each C 3 and C 4. Clypeal margin rounded.

Mesosoma. Mesosoma 1.30–1.36 × as long as broad. Scutellum moderately depressed, 0.77–0.81 × as long as broad, frenal area indistinct. Propodeum 0.45–0.48 × as long as scutellum; nucha short. Fore wing 2.24–2.28 × as long as its maximum width; basal cell with several hairs; basal vein pilose; speculum open below; M 0.90 × as long as PM and 2.10–2.22 × as long as S; stigma small.
