(Figs 14, 15)  
 Diagnosis. Antenna (Fig. 15) with scape and pedicel distinctly flattened, F1–3 weakly flattened, F4–5 not flattened, antenna dark brown with F5 white; occipital margin with a rounded edge; pronotal collar with a carina along anterior margin (Fig. 14); mesoscutum (Fig. 14) smooth and shiny, with weak traces of reticulation on sidelobes and on anterior part of midlobe, notauli distinct throughout, as deep parallel grooves in posterior two-thirds, midlobe with one pair of long and strong setae; mesoscutellum smooth and shiny (Fig. 14); propodeum with two complete and parallel median carinae (Fig. 14); fore wing hyaline with median one-third infuscate, speculum open below and towards base of wing (Figs 14, 15); length of body female 1.7–1.8mm.   
Female holotype: length of body 1.7mm.  
Antenna dark brown with F5 white. Frons golden-green. Vertex metallic purple in front of anterior ocellus, metallic blue in posterior part. Mesoscutum with midlobe golden-purple with anterior one-third metallic purple, sidelobes metallic purple; mesoscutellum golden-purple, with lateral and posterior margins metallic bluish-purple; dorsellum golden-green; propodeum black with metallic tinges. Coxae and femora dark brown, hind femur with apex white; fore and mid tibiae white, hind tibia white with basal one-half dark brown; tarsi white. Fore wing hyaline with median one-third infuscate, hind wing hyaline. Petiole black with metallic tinges. Gaster with Gt 1 dark brown with metallic purple tinges, remaining tergites dark brown.  
Antenna with scape and pedicel distinctly flattened, F1–3 weakly flattened, F4–5 not flattened. Frons with strong reticulation. Vertex with very weak reticulation. Frontofacial suture V-shaped. Subtorular sutures present. Occipital margin with an edge.
