Male. Generally grayish yellow to grayish ocher. Head in dorsal aspect anterior margin forming approximately 90º angle, in facial aspect usually ocher with tiny brown patterns on frontoclypeus, nearby apical margin of crown with pale grayish yellow pattern, apical margin of crown without black spot, vertex without any spots. Face in lateral aspect nearly flat, posterior margin of antennal ledge closer to apical margin of anteclypeus than apical margin of crown. Pronotum usually grayish yellow, fore margin without dark patches, posterior margin usually darker, first plural sclerite in lateral aspect subtriangular, without spots. Scutellum with brown scutellar spots, inner margin of scutellar spots yellow, outer margin of scutellar spots black. Both pronotum and scutellum with distinct median carina. Forewing usually pale brown to ocher, with many tiny dark brown spots. Tergal apodemes of 2nd abdominal base short, divided by distinctly wide rounded notch. Sternal apodemes triangular, distinctly long, slightly convergent, inner margin with irregular shape.

Male genitalia. Pygofer appendage narrow, distinctly widened beyond midlength, tapered distally. Style comparatively narrow, straight, elongated, apical tooth small bent inward. Aedeagus in lateral aspect very narrow, 1.5 times wider than length, subparallel margined, without apical tooth.

Female. Usually grayish yellow to grayish ocher and comparatively brighter than in male. Head in facial aspect usually ocher with pale ocher obliqued stripe and smoky brown patches on frontoclypeus, apical margin of crown without black spot, vertex without any spots. Face in lateral aspect almost flat, center of eye almost half-way between apical margin of crown and apical margin of lorum. Pronotum usually brownish yellow with oblique pale ocher stripe bifurcated from middle line, fore margin more strongly produced than in male, without dark patches, first plural sclerite in lateral aspect subpentagonal, without spots. Scutellum with brown scutellar spots, inner and outer margin of scutellar spots with black stripe. Forewing usually pale brown to ocher, with many tiny dark brown spots.

Female genitalia. Valvulae-II with 5–6 preapical teeth each.

Length. Male 4.7−4.9mm, female 5.0– 5.2mm.
