Diagnosis. Antenna flattened, scape widest at apex ( Figs 177 View Figs 171–177 , 226 View Figs 224–232 ); frons with upper border distinct ( Fig. 177 View Figs 171–177 ); ocelli small, ratio POL/posterior ocellus width = 3.2 ( Fig. 175 View Figs 171–177 ); pronotal collar without a carina along anterior margin ( Figs 170 View Figs 164–170 , 175 View Figs 171–177 ); midlobe of mesoscutum with two pairs of setae ( Figs 170 View Figs 164–170 , 175 View Figs 171–177 ); fore wing triangular and infuscate with two hyaline areas, one L-shaped spot below marginal vein and one band close to apical margin ( Figs 175 View Figs 171–177 , 216 View Figs 214–223 ); hind tarsus with T1–3 white, T4 dark brown ( Fig. 176 View Figs 171–177 ); length of body both sexes 1.1mm.
Female holotype: length of body 1.1mm.
Antenna dark brown. Frons golden-green. Vertex metallic bluish-green. Mesoscutum, mesoscutellum, dorsellum and propodeum metallic bluish-purple. Coxae, femora, mid and hind tibiae dark brown; fore tibia white with basal one-third dark; all tarsi with T1–3 white and T4 dark brown. Fore wing triangular and infuscate with two hyaline areas, one L-shaped spot below marginal vein and one band close to apical margin; hind wing hyaline. Petiole dark brown. Gaster with Gt 1-3 dark brown with lateral parts metallic purplish; remaining tergites dark brown with metallic tinges.
Antenna flattened, scape widest at apex. Frons with weak reticulation; frontofacial suture V-shaped; upper border distinct. Vertex with strong reticulation; ocelli small. Subtorular sutures present. Occipital margin rounded.
Pronotal collar without a carina along anterior margin. Mesoscutum and mesoscutellum with weak reticulation, meshes small and slightly transverse; notauli narrow and complete; midlobe of mesoscutum with two pairs of setae. Dorsellum convex and smooth. Propodeum reticulate with median part smooth, without median carina; callus with two setae. Fore wing triangular; speculum closed; with a stigmal hairline and with radial cell bare.
Petiole very short, just a narrow band. Gaster oval-shaped; tergites with very weak reticulation.
