Description. Body length (from apex of vertex to tip of forewings): Brachypterous: male 3.9–4.2 mm, female 4.2–4.4 mm; Macropterous: male 4.5–5.1 mm, female 4.9–5.1 mm.

General colour brown or ochreous, abdomen dark brown. Vertex and pronotum pale ochreous ( Fig. 7 ). Frons with one pair of dark oval patches. Postclypeus dark brown, anteclypeus stramineous with pale yellow median callus, genae pale yellow, lorae diffusely dark ( Fig. 8 ).

Vertex ( Fig. 35 ) shorter in middle than widest breadth (1.0:1.5). Frons ( Fig. 36 ) longer in middle than widest breadth (1.6:1.0). Pronotum ( Fig. 35 ) broader than long (3.8:1.0). Froewings ( Fig. 38 ) with about five apical cells. Hind tibia with 2 distinct lateral spines, spinal formula of hind leg 7–8–2.

Male genitalia. Pygofer ( Fig. 40 ) symmetrical, irregularly quadrate in left view, dorsal margin narrow, deeply excavated to accommodate anal tube, ventral margin broad. Anal tube ( Figs 43–44 ) short, anal style not surpassing anal tube. Gonostyli ( Figs 40–42 ) bilaterally symmetrical, in lateral view about 1.7 times as long as broad, axe-like, basal 1/3 broad, then narrowing, with triangular process arising from base of dorsal margin, a strong hook-like process arising from laterodorsal margin, acute tip bent lateroventrad, with triangular process, pointing to inner side, arising from dorsal margin in side view. Aedeagus ( Figs 40, 43–44 ) elongate and sclerotized; shaft slender, Sshaped in lateral view, base very broad, cystiform-like, then becoming slender. Periandrium ( Figs 40, 44 ) surrounding penis at base, ringed in basal part, arising from two long processes, almost equal to aedeagus in length.
