( Figs 124, 125 , 706 ) Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 ( Fig. 706 ); genal carina absent; mesoscutum and mesoscutellum ( Fig. 124 ) with strong reticulation with elongate meshes, mesoscutellum with submedian grooves weak, indicated in the reticulation; hind coxa with a carina along posterior margin; gaster ( Fig. 124 ) 2.3× as long as wide, with short Gt 2 , 0.13× as long as wide, and Gt 4 0.45× as long as wide, Gt 2 0.36× as long as Gt 4 , medio-basal Gt 1 with a transverse edge dorsally, with weaker reticulation and more shiny than remaining tergites. Female holotype : length of body 2.2mm ( paratypes 1.9–2.2mm ). Scape yellowish-brown, pedicel and flagellum dark brown. Head with frons metallic greenish blue with scrobes black with metallic tinges and clypeus dark brown; vertex black with metallic blue tinges. Mesosoma golden-green. Legs with fore and mid coxae metallic greenish-blue, hind coxa golden-green; fore and mid trochanters dark brown, hind trochanter black; femora golden-green with apex yellowish-brown; tibiae and tarsi yellowish-brown, T4 dark brown. Petiole black. Gaster with Gt 1 golden-green, Gt 2-7 metallic greenish-blue; gonoplac black. Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation. Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without median groove, with five setae in one row close to notauli. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct, slightly curved and diverging towards posterior part; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with strong sculpture. Propodeum with a triangular median carina, concave; 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 three setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken. Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a transverse edge dorsally, more shiny than remaining tergites which have rather strong reticulation.
