Diagnosis. Flagellum thick, second flagellomere 1.9X as wide as pedicel ( Fig. 65 View FIGURES 56 – 68 ); frontal suture reaching eyes at level equal with anterior margin of anterior ocellus ( Fig. 35 View FIGURES 35 – 38 ); forewing costal cell ventrally with a sparse row of setae in apical ½ (as in Fig. 51 View FIGURES 47 – 53 ); propodeum with irregular sculpture medially or completely smooth ( Fig. 38 View FIGURES 35 – 38 ), propodeal callus with 5 setae.

Description. FEMALE. Length 1.9–2.4 mm. Scape dark brown with basal 2/3 of outer surface yellowishbrown, pedicel and flagellum dark brown. Frons below level of toruli black with green and blue tinges, between level of toruli and frontal suture metallic purple, above frontal suture metallic bluish-purple. Vertex inside ocellar triangle golden-purple, outside ocellar triangle metallic bluish-purple. Mesoscutum golden-purple, lateral parts of sidelobes metallic bluish-purple. Scutellum metallic bluish-green, with purple tinges in posterior ¼. Propodeum metallic bluish-green, medially with purple tinges. Coxae dark and metallic; femora and tibiae dark brown; mid tarsus completely white, fore and hind tarsi with tarsomeres 1–3 white, 4 dark brown. Forewing hyaline. Gaster with tergite 1 metallic bluish-green, tergite 2 metallic bluish-purple, remaining tergites golden-purple.

Antenna as in Fig. 65 View FIGURES 56 – 68 . Frons with weak reticulation below level of toruli except smooth just below toruli, but with raised, strong reticulation between toruli and frontal suture, and smooth or with very weak reticulation above frontal suture ( Fig. 35 View FIGURES 35 – 38 ); frontal suture reaching eyes at level equal with anterior margin of anterior ocellus. Vertex with engraved, strong reticulation inside ocellar triangle, but smooth outside ocellar triangle ( Fig. 36 View FIGURES 35 – 38 ). Occipital margin rounded. Eyes with sparse, scattered hairs ( Figs 35, 36 View FIGURES 35 – 38 ).

Pronotum without transverse carina close to posterior margin ( Fig. 37 View FIGURES 35 – 38 ). Mesoscutum with raised, strong reticulation ( Fig. 37 View FIGURES 35 – 38 ); notauli as narrow distinct grooves in anterior 1/3, as wide impressions in posterior 2/3. Scutellum with raised, rather strong reticulation in anterior 2/3 ( Fig. 37 View FIGURES 35 – 38 ) and posterior 1/3 with very weak reticulation except posterior margin smooth; with 1 pair of setae. Propodeum completely smooth or with irregular sculpture in median part ( Fig. 38 View FIGURES 35 – 38 ); callus with 5 setae. Forewing speculum closed below; forewing costal cell ventrally with a sparse row of setae in apical ½.

Petiole 0.2X as long as wide, smooth. Gaster ovate with apex acuminate; tergites smooth.
