Thorax. Prothorax 2.3–3.3 mm long in males, 2.5–4.1 mm long in females, elongate, entirely brown to dark brown with one or two yellow spot(s) at anterior broad section. Meso- and metanotum generally blackish brown except yellow region at anterior margin of scutum and yellow scutellum.

Legs. Foreleg: coxa with posterior surface generally yellow with longitudinal brown stripe from distal half to one-third; anterior surface generally yellow with longitudinal brown stripe ( Fig. 17B View Fig ). Femur posterior surface generally yellow with few brown spots, anterior surface entirely dark brown. Yellow femoral major process at proximal two-fifths of profemur length, yellow posteroventral row of processes present on distal three-fifths of profemur length ( Fig. 17B View Fig ). Tibia generally yellow, gradually brown towards apex. Tarsus brown to dark brown. Mid- and hindlegs: coxa entirely dark brown ( Fig. 17E View Fig ). Trochanter dark yellow. Femur to their tarsi yellow to dark yellow, pretarsal claws with three or four apical teeth, arolium present.

Wings. Forewing 7.6–11.0 mm long in males, 9.0– 12.6 mm long in females, elongate, membrane hyaline, venation generally dark brown except yellow on wing base. Pterostigma dark brown. Radius Anterior (RA) and Radius Posterior (RP) partly fused at wing apex ( Fig. 17F View Fig ). Media (M) and Radius (R) fused along approximately basal one-quarter of wing length, M vein posteriorly retracted to Cubitus (Cu), forming small radial triangle (rt) ( Fig. 17F View Fig ). Hind wing 6.5–9.1 mm long in males, 7.0– 10.5 mm long in females, elongate, membrane hyaline, venation generally dark brown except yellow on wing base. Pterostigma dark brown.

Anterotergite of tergite II generally black with yellow stripe at anterior margin, posterotergite generally black with yellow stripe at lateral margins. Tergites III to V with triangular black spot, yellow on anterior regions ( Fig. 17H View Fig ). Tergites VI to VIII generally yellow with black stripe at posterior margins. Sternites I and II entirely black. Sternites III to VII generally yellow with black stripe at posterior margins.
