( Figs 3 View Fig , 88–92 View Figs 88–94 , 210 View Figs 205–213 , 221 View Figs 214–223 )

Diagnosis. Antenna flattened, scape widest at apex ( Fig. 89 View Figs 88–94 , 221 View Figs 214–223 ); frontofacial suture straight ( Fig. 90 View Figs 88–94 ); vertex flat, in same plane as thoracic dorsum, with long and strong setae ( Fig. 90 View Figs 88–94 ); head triangular in lateral view ( Fig. 89 View Figs 88–94 ); pronotal collar without a carina along anterior margin ( Fig. 88 View Figs 88–94 ); midlobe of mesoscutum with one pair of long and strong setae ( Figs 88, 89 View Figs 88–94 ); fore wing with apical one-third with median one-third infuscate and with an infuscate spot just below stigmal vein and one infuscate spot further down below level of stigmal vein ( Fig. 210 View Figs 205–213 ), to predominantly infuscate with dorso-apical and ventro-apical one-third and basal one-third hyaline ( Figs 3 View Fig , 88, 89 View Figs 88–94 ); hind tarsus with T1&4 whitish, T2&3 infuscate ( Fig. 89 View Figs 88–94 ); length of body female 0.7–1.4mm, male 1.0– 1.3mm.

Female holotype: length of body 1.4mm.

Antenna dark brown. Frons golden below level of toruli, golden-green above this level. Vertex metallic bluish-purple. Mesoscutum, mesoscutellum and dorsellum metallic purple. Propodeum brown with metallic purple tinges. Legs with fore coxa white, mid and hind coxae dark brown; fore and mid femora white with dorsal margin infuscate, hind femur dark brown with ventral part infuscate; tibiae white; tarsi with T1&4 whitish, T2&3 infuscate. Fore wing hyaline with apical one-third with median one-third infuscate and with an infuscate spot just below stigmal vein and one infuscate spot further down below level of stigmal vein; hind wing hyaline. Petiole dark brown. Gaster with Gt 1-2 metallic purple, remaining tergites dark brown with metallic tinges.

Antenna flattened with all flagellomeres distinctly separated, scape widest at apex. Frons and vertex with strong reticulation, reticulation on frons weaker than on vertex. Frontofacial suture straight. Subtorular sutures present but very short. Occipital margin rounded.

Pronotal collar without a carina along anterior margin. Mesoscutum with strong reticulation; notauli distinct in anterior one-half; midlobe of mesoscutum with one pair of long and strong setae, attached in posterior one-half of mesoscutum. Mesoscutellum smooth and shiny. Dorsellum convex and smooth. Propodeum smooth, without median carina; 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.

Relative measurements: head length dorsal 17; head length frontal 19; head width 34; POL 6; OOL 4; lateral ocellus maximum width 3; eye length 14; malar space 6; mouth width 10; mesosoma length 42; mesosoma width 28; mesoscutellum length 17; mesoscutellum width 16; fore wing length 66; fore wing width 39; marginal vein length 31; postmarginal vein length 4; stigmal vein length 5; fore wing marginal fringe length 6; gaster length 50; gaster width 28.

Variation in paratype material. Length of body: 0.7–1.4mm. Vertex metallic bluish-purple or bluish-green. Mesoscutum metallic purple, metallic bluish-purple or metallic bluish-green, with strong reticulation to smooth. Mesoscutellum metallic purple, bluish-purple or bluish-green. Fore wing hyaline with apical one-third with median one-third infuscate and with an infuscate spot just below stigmal vein and one infuscate spot further down below level of stigmal vein, or predominantly infuscate with dorso-apical and ventro-apical one-third and basal one-third hyaline.

Male ( Figs 91, 92 View Figs 88–94 ). Length of body 1.0– 1.3mm. Antenna weakly flattened; flagellomeres with setae confined to a basal whorl. Mesoscutum with midlobe golden-green, sidelobes metallic bluish-purple, or completely metallic purple. Mesoscutellum golden-red with lateral and posterior parts metallic bluish-purple. Gaster with a white spot medially in anterior one-half. Otherwise similar to female.
