( Figs 37–48 , 57, 60 , 67–68 ) Diagnosis . Achrysocharoides robinicolus is very similar to A. robiniae but differs in having a narrower male scape ( Figs 44 , 68 ), which is 3.0X as long as wide ( holotype ) (1.8X as long as wide in holotype of A. robiniae , Figs 32 , 66 ), anteromedian white spot in male gaster triangular and small, reaching to posterior margin of 1st or 2nd tergites ( Figs 57, 60 ) (shaped as a pentagon in A. robiniae , Figs 56, 59 ), hind coxae in both sexes with base brown to metallic ( Figs 47–48 ) (completely white in both sexes of A . robiniae , Figs 35–36 ). Description . FEMALE. Length 1.2–1.4 mm . Scape white with apical 1/3 infuscate; pedicel and flagellum brown with weak metallic tinges. Frons below frontal suture golden-green to golden-red, antennal scrobes golden-red, above frontal suture metallic bluish-purple with metallic green tinges. Vertex inside ocellar triangle golden-red, outside ocellar triangle golden-green. Mesoscutum and scutellum metallic bluish-green. Propodeum metallic blue with green tinges. Legs white, hind coxa with base brown to metallic. Wings hyaline. Gaster with first two tergites golden-green, remaining tergites dark brown with metallic green tinges. FIGURES 37–42.

Mesoscutum with midlobe with raised and strong reticulation, sidelobes with fine and weak reticulation; notauli as smooth impressions in posterior 2/3.
