(Figs 86, 87, 953, 1007)
Diagnosis (female). Antenna with a weak constriction between C1 and C2 (Fig. 1007); genal carina absent; mesosoma bright metallic bluish-green; mesoscutum and mesoscutellum (Fig. 86) with strong reticulation, mesoscutellum with weak submedian grooves; dorsellum with or without median carina; propodeum (Fig. 86) with median carina triangular, anterior part distinctly elevated, callus with two setae; hind coxa with a carina along posterior margin; gaster (Fig. 86) 3.1× as long as wide, with Gt 2 0.06× as long as Gt 4, Gt 1 with weak reticulation and shiny in posterior half. Brightly metallic species in both sexes (Figs 86, 87).
Female holotype: length of body 2.9mm (paratypes 2.3–3.2mm).
Scape yellowish-brown, pedicel and flagellum dark brown to black. Head metallic bluish-green, clypeus dark brown, antennal scrobes black. Mesosoma bright metallic bluish-green. Legs with coxae metallic bluish-green, mid coxa with weaker metallic tinges; trochanters pale brown; femora black with metallic blue tinges and with apex yellowish-brown; tibiae yellowish-white; T1–3 yellowish-white, T4 pale brown. Petiole black. Gaster with Gt 1,6 metallic bluish-green, Gt 2-5 metallic purple, Gt 7 black with metallic green tinges; gonoplac black.
Antenna with a weak constriction between C1 and C2. Face below level of antennal toruli and scrobes with weak reticulation, frons with strong reticulation; without genal carina. Vertex with strong reticulation.
Mesoscutum with strong reticulation, meshes predominantly isodiametric but with elongate meshes in posterior one-third of midlobe; midlobe without median groove, with ten scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate, submedian grooves ±distinct and diverging towards posterior part. Dorsellum with strong reticulation, with median carina. Propodeum with median carina triangular, anterior part distinctly elevated; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin. Fore wing with five setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.
Petiole very short, just a narrow band. Gaster very elongate; medio-basal Gt 1 without edge or carina dorsally, this part smoothly rounded; Gt 1 with weak reticulation and shiny in posterior half, remaning tergites with strong reticulation.
