Diagnosis. Body including legs and entire frons yellowish-brown to pale brown ( Figs 1, 2 View FIGURES 1–4 ), antenna with F1–3 dark brown, F4 and clava yellowish-white ( Fig. 1 View FIGURES 1–4 ), fore wing infumate with median one-third darker ( Figs 1, 2 View FIGURES 1–4 ); pronotal collar without a carina along anterior margin ( Fig. 2 View FIGURES 1–4 ); midlobe of mesoscutum with two pairs of long and strong setae ( Fig. 2 View FIGURES 1–4 ); mesoscutellum with sublateral grooves ±straight in lateral part, joining in posterior part ( Fig. 2 View FIGURES 1–4 ).

Description (female holotype). Length 1.9mm. Frons and vertex with weak reticulation; Pronotal collar without a carina along anterior margin. Mesoscutum, mesoscutellum, dorsellum and propodeum with very weak reticulation, almost smooth; midlobe of mesoscutum with two pairs of long and strong setae; mesoscutellum with sublateral grooves joining in posterior part; propodeal callus with six setae. Fore wing with six setae on dorsal surface of submarginal vein; with 20 admarginal setae; costal cell with a row of ten setae on ventral surface, apico-dorsal margin with three setae. Gaster short ovate.

Colour. Head including antennal scrobes yellowish-brown, occiput around occipital foramen dark brown. Antennae with scape yellowish-brown, pedicel and F1–3 dark brown, F4 and clava yellowish-white.
