Head slightly narrower than pronotum; vertex roundly prominent, pale yellow without black spot at apex, with pair of small black spots near ocelli and pair of large black spots near ocelli; medial length of vertex 1.2 times as long as length next to eyes and half as long as width of head; frontoclypeus pale yellow with narrow blackish stripe and wide blackish band near anterior margin; clypellus and lorum pale yellow and immaculate; gena pale yellow with small blackish marking below antenna. Pronotum 2.1 times as wide as long, slightly longer than mesonotum, brown with wide longitudinal pale stripe and 2 pairs of blackish spots anteriorly; pale stripe of pronotum with pair of brownish small spots anteriorly; mesonotum brown with longitudinal pale stripe and pair of brownish spots medially. Fore wing pale yellowish semitransparent; ventral surface of thorax, legs and abdominal segments pale yellow.

Male genitalia. Pygofer very long and gradually tapered apically in lateral view, with a tuft of very long macrosetae apically and a few shorter macrosetae subapically, without pygofer process. Subgenital plate distinctly widened basally, as long as 1/3 length of pygofer, with uniseriate row of 2–3 macrosetae subbasally. Style slender, with long apodeme; preapical lobe small; apophysis (apical process) short, directing laterally, with 3 short hairs. Connective with pair of long processes; processes as long as connective, gradually tapered and pointed apically; arms nearly parallel. Aedeagus robust; shaft 1.5 times as long as basal apodeme, wide in lateral view, hooked dorsad at apex, without apical processes; gonopore subapical on ventral surface.

Body length (mean). ♂, 4.9–5.4 mm (5.1 mm); ♀, 5.6–6.1 mm (5.7 mm).
