( Figs 152, 153 View Figs 152–157 , 215 View Figs 214–223 , 227 View Figs 224–232 , 236 View Figs 233–238 )

Diagnosis. Antenna flattened, scape widest at apex, all flagellomeres distinctly separated ( Figs 153 View Figs 152–157 , 227 View Figs 224–232 ); frontofacial suture straight ( Fig. 236 View Figs 233–238 ); pronotal collar with a weak carina along anterior margin ( Fig. 152 View Figs 152–157 ); midlobe of mesoscutum with one pair of strong setae ( Figs 152, 153 View Figs 152–157 ); fore wing with basal one-half weakly infuscate, almost hyaline, apical one-half strongly infuscate with two hyaline spots ( Figs 152, 153 View Figs 152–157 , 215 View Figs 214–223 ); hind tarsus completely pale (infuscate to white) ( Fig. 153 View Figs 152–157 ); length of body female 1.7–2.0mm.

Female holotype: length of body 1.7mm.

Antenna dark brown. Frons golden-green. Vertex metallic bluish-purple. Mesoscutum, mesoscutellum and dorsellum metallic bluish-purple. Propodeum metallic purple. Coxae and femora dark brown with metallic tinges; fore and mid tibiae white, hind tibia dark brown; tarsi white to slightly infuscate. Fore wing predominantly infuscate, weakly infuscate in basal one-half and darker in apical one-half, apical one-half with two large hyaline spots, hind wing hyaline. Petiole black with metallic tinges. Gaster golden-purple with metallic bluish-purple tinges.

Antenna flattened, scape widest at apex. Frons with strong reticulation. Vertex with strong reticulation in anterior one-half, with very weak reticulation in posterior one-half. Frontofacial suture straight. Subtorular sutures present but short. Occipital margin rounded.

Pronotal collar with a weak carina along anterior margin. Mesoscutum with strong reticulation; notauli distinct in anterior one-half; midlobe of mesoscutum with one pair of strong setae. Mesoscutellum convex with strong reticulation, smooth along hind margin. Dorsellum flat and almost smooth. Propodeum smooth, some parts with weak reticulation; callus with two setae. Fore wing speculum closed; with a stigmal hairline and with radial cell bare.

Petiole very short, just a narrow band. Gaster ovate-elongate; Gt 1-2 smooth, remaining tergites with weak reticulation.

Relative measurements: head length dorsal 20; head length frontal 24; head width 43; POL 8; OOL 5; lateral ocellus maximum width 3,2; eye length 19; malar space 6; mouth width 11.5; mesosoma length 54; mesosoma width 36; mesoscutellum length 22; mesoscutellum width 21.5; fore wing length 89; fore wing width 60; marginal vein length 47; postmarginal vein length 6.5; stigmal vein length 7; fore wing marginal fringe length 3; gaster length 65; gaster width 33.

Variation in paratype material. Length of body: 1.9–2.0mm. Fore wing predominantly infuscate, weakly infuscate in basal one-half and darker in apical one-half, apical one-half with two large hyaline spots, or with basal one-half hyaline.
