 Diagnosis. Antenna dark brown with F5 pale brown, scape widest at apex, F1–3 flattened, F4 moderately flattened, F5 not flattened and long and narrow (Figs 197, 198); pronotal collar without a carina along anterior margin (Fig. 197); midlobe of mesoscutum with one pair of ±strong setae (Fig. 197); fore wing weakly infuscate (Fig. 198); legs predominantly white with hind coxa dark brown at base (Fig. 198); length of body female 0.9–1.1mm.   
Female holotype: length of body 0.9mm.  
Antenna dark brown with F5 pale brown. Frons below frontofacial suture golden-green, above suture metallic purple. Vertex metallic bluish-green. Mesoscutum golden-green; mesoscutellum golden-green with median part golden-red; dorsellum and propodeum golden-green. Legs white with fore tarsus infuscate and hind coxa dark brown in basal one-half. Fore wing weakly infuscate; hind wing hyaline. Petiole dark brown with metallic tinges. Gaster metallic bluish-green with median part golden-red.  
Antenna predominantly flattened, except F5 which is narrow, scape widest just below apex. Frons with strong reticulation. Vertex with very weak reticulation, partly smooth. Frontofacial suture ±straight. Subtorular sutures present. Occipital margin rounded.  
Pronotal collar without a carina along anterior margin. Mesoscutum with weak reticulation on midlobe, strong reticulation on sidelobes; notauli distinct in anterior one-third; midlobe with one pair of ±strong setae.
