Description.

Female (holotype, Figs 1-6 ). Body length 2.1 mm; Head with metallic tinge, vertex with small yellow area outside of each posterior ocellus, and with a triangular yellow T-shaped area in front of anterior ocellus; eye red; ocelli dark red; antenna with scape, pedicel and flagellum yellow; mandible dark brown. Mesosoma green with strong metallic tinge. Legs yellow except all coxae mostly dark green with metallic luster, as on mesosoma, and apical tarsomeres brown (Fig. 2 ). Metasoma with tergum I yellow except for metallic tinge in a triangular anteromedial area; terga II-IV entirely yellow; tergum V medially with a round green or orange metallic pattern; tergum VI mostly with green metallic tinge, laterally with small yellow part round like, yellow part not large than metallic tinge area; tergum VII fully dark green with metallic tinge. Ovipositor black with green metallic tinge; hypopygium fully black with green metallic tinge; outer plate of ovipositor mostly black.

Head (Fig. 3 ) 1.1 × as wide as high, 1.5 × as wide as midlobe of mesoscutum. Ocellar triangle surrounded by shallow grooves (vertex collapses along these lines in air-dried specimens). POL 3.8 × OOL. Torulus at lower margin of eye. Malar space about 0.4 × eye height. Malar sulcus strongly curved.

Antenna (Fig. 4 ) with scape 4.0 × as long as wide, not reaching anterior ocellus; pedicel 1.6 ×, F1 1.6 ×, F2 1.5 ×, F3 1.0 ×, and clava 1.9 × as long as wide; C3 short with rounded apex, without a terminal spine.

Mesosoma 1.7 × as long as wide, convex. Pronotum in dorsal view medially very short. Mesoscutum with midlobe about 1.2 × as long as wide, with median line very weak, and with a single row of 3 or 4 adnotaular setae. Scutellum 1.2 × as long as wide, with anterior pair of setae in posterior half, and submedian and sublateral grooves strong and parallel to each other. Propodeum medially as long as dorsellum, with a median carina but without paraspiracular carinae; callus with 4 or 5 setae; with a groove extending from spiracle to posterior margin of propodeum.

Fore wing (Fig. 5 ) hyaline, 1.9 × as long as wide. Speculum large, extending from parastigma to stigmal vein. Discal setae short. CC 1.6 × as long as MV; MV thick, 6.0 × as long as wide; MV 2.4 × as long as STV, with 7 marginal setae (about 0.5 × as long as STV); STV rather thick; PSV not thicker than MV, short, stub-like. Hind wing rounded apically, 4.5 × as long as wide.

Legs. Metafemur 3.5 × as long as wide.

Metasoma (Fig. 6 ) 1.2 × as long as mesosoma, 2.0 × as long as wide; hypopygium extending to about half length of metasoma; cercal setae subequal in length; ovipositor sheath slightly protruding.

Variation (paratypes, Figs 7-12 ). Body length 1.9-2.1 mm. Metasomal tergum V with metallic area small to large size which occupying most of the tergum (Figs 7 , 9 , 11 ); tergum VI with metallic pattern area large to very large, relatively, with yellow part laterally from middle size to small (Figs 8 , 10 , 12 ); hypopygium from dark brown to black; outer plate of ovipositor mostly black to entirely black with metallic reflections (Figs 8 , 10 , 12 ). Pedicel 1.6-1.7 ×, F1 1.6-1.7 ×, F2 1.5-1.6 ×, F3 0.9-1.0 ×, clava 1.8-1.9 × as long as wide. POL 3.8-4.0 × OOL. EL 1.9-2.4 × MSP. ML 1.6-1.7 × MW. STL 1.1-1.2 × STW. FWL 1.8-1.9 × FWW. HWL 4.4-4.9 × HWW. CC 1.5-1.6 × MV. MV 2.3-2.4 × STV. GL 2.0-2.3 × GW. MFL 3.5-3.8 × MFW.
