Clypeus except for dorsal part, mandible except for teeth, palpi and ventral surfaces of scape and pedicel and basal segments of flagellum yellowish brown to whitish yellow. Flagellum usually with subapical white band. Bases of T I and T II whitish yellow to white. Each posterior margin of T I to T III, T VII and subgenital plate narrowly tinged with reddish brown. Ovipositor reddish brown. Wings hyaline except for apical clouded area of fore wing. Veins and pterostigma blackish brown except for yellowish-brown wing base. Fore and mid legs except for coxae dark yellowish brown to blackish brown. Fore and mid coxae whitish yellow. Hind leg blackish brown and partly tinged with dark reddish brown except for bases of TS II and TS III more or less tinged with whitish yellow.

Male (n = 5). Similar to female except for coloration ( Figs 3 C , 10 B , 13 A). Head 0.7–0.75 × as long as wide. Clypeus 1.5–1.7 × as broad as high.
