( Figs 158, 159 View Figs 158–163 , 229 View Figs 224–232 , 237 View Figs 233–238 )

Diagnosis. Antenna flattened, scape widest at apex ( Figs 159 View Figs 158–163 , 229 View Figs 224–232 ); frontofacial suture straight ( Fig. 237 View Figs 233–238 ); pronotal collar without a carina along anterior margin ( Fig. 158 View Figs 158–163 ); midlobe of mesoscutum with one pair of strong setae ( Figs 158, 159 View Figs 158–163 ); fore wing hyaline with a strong infuscate band below stigmal vein, reaching to hind margin of wing, with apical margin infuscate and with an infuscate spot below marginal vein ( Fig. 158 View Figs 158–163 ); stigmal vein elongate, ca 3.5× as long as wide ( Fig. 158 View Figs 158–163 ); length of body female 1.7–2.2mm.

Female holotype: length of body 2.2mm.

Antenna dark brown. Frons golden-green. Vertex metallic purple. Mesoscutum metallic purple. Mesoscutellum, dorsellum and propodeum metallic bluish-purple. Coxae, femora and tibiae dark brown; tarsi with T1–3 white, T4 dark brown. Fore wing hyaline with a strong infuscate band below stigmal vein, reaching to hind margin of wing, with apical margin infuscate and with an infuscate spot below marginal vein; hind wing hyaline. Petiole black. Gaster metallic purple.

Antenna flattened, scape widest at apex. Frons and vertex with strong reticulation. Frontofacial suture straight. Subtorular sutures present but difficult to see as they are short and dark. Occipital margin rounded.

Pronotal collar without a carina along anterior margin. Mesoscutum and mesoscutellum with strong reticulation; notauli distinct in anterior one-half; midlobe with one pair of strong setae. Dorsellum convex, with strong reticulation. Propodeum with weak reticulation, without median carina; callus with two setae. Fore wing speculum closed, stigmal vein elongate, without stigmal hairline but with radial cell bare.

Petiole very short, just a narrow band. Gaster elongate; Gt 1,2,7 with weak reticulation, remaining tergites with strong reticulation.

Relative measurements: head length dorsal 21.5; head length frontal 30; head width 55; POL 11; OOL 6.5; lateral ocellus maximum width 4; eye length 23; malar space 9; mouth width 14.5; mesosoma length 67; mesosoma width 53; mesoscutellum length 31; mesoscutellum width 32; fore wing length 110; fore wing width 72; marginal vein length 64; postmarginal vein length 4; stigmal vein length 14.5; fore wing marginal fringe length 3; gaster length 85; gaster width 47.5.

Variation in paratype material. Length of body 1.7–2.2mm. Frons golden-green or dark brown with metallic tinges. Mesoscutellum with strong to weak reticulation to almost smooth. Mesoscutum and mesoscutellum metallic bluish-green, bluish-purple or purple. Fore wing in paratypes with infuscate parts along apical margin and below marginal vein weak. Gaster metallic purple or dark brown with metallic bluish-purple tinges.
