Description. Male ( Figs. 1 View FIGURE 1 , 2A View FIGURE 2 , 3 View FIGURE 3 , 4 View FIGURE 4 ).

Head. Head small. Vertex flattened. Eyes enlarged and prominent. Ocellus not visible. Antennal scape large, wider than frontal rostrum. 5th segment of maxillary palpus strongly thickened, 3th segment as long as 5th, but longer than 4th ( Fig. 3A View FIGURE 3 ).

Thorax. Pronotal disc trapezoidal, anterior margin narrowed and straight; posterior margin convex ( Fig. 3B View FIGURE 3 ). Pronotum with carinae between disc and lateral lobes. Metanotal gland with sparse hairs on the upper portion ( Fig. 3D View FIGURE 3 ). Legs. Inner tympanum slit-like, partly covered ( Fig. 3E View FIGURE 3 ). Outer tympanum open and round-shaped, but shorter than the inner one ( Fig. 3F View FIGURE 3 ). Hind tibia with five outer dorsal spurs and six inner dorsal spurs on the apical half, three small spines on the basal half of hind tibia, with outer dorsal spurs in a straight line ( Fig. 3G View FIGURE 3 ). Tegmina and wings. Forewing venation: Sc long and little curved forward, with 9–11 branches reaching anterior margin of forewing. CuPa straight, forking into CuPaα and CuPaβ over half the length of forewing. PCuA straight at basal part and curved at 1/4 of the forewing basally, approximately forming a right angle. Chord1–3 normal, sub-c1 developed and hexagon-shaped. Pilar exist. Harp with six oblique veins. Mirror with one straight dividing vein; sub-mi slender. Apical area developed, longer than mirror ( Fig. 2A View FIGURE 2 ).

Abdomen. Cercus thin and elongate. Lobes of male supra-anal plate separated from each other inconspicuously, posterior side of these lobes densely covered by short setae ( Fig. 3C View FIGURE 3 ). Genitalia. Epiphallus: the upper acute hooks small and slightly forward curved, apex possessing a pair of larger lower hooks provided with an apical round inflation, a tuft of hair at the apical side of this inflation ( Fig. 4 View FIGURE 4 ).

Female. Similar to male ( Fig. 5A, B, E, F, G View FIGURE 5 ), but basal area of forewings not as wide as those of male ( Figs. 1 View FIGURE 1 , 2B View FIGURE 2 ). Ovipositor short, with teeth on the ventral side of apical part ( Fig. 5C, D View FIGURE 5 ).

Coloration.

Body overall yellowish. Two black spots on the pronotal disc. A black line just under lateral carina. Area around inner tympanum black. A black line on the dorsal side of fore- and mid-tibia on apical half. Three spots on the dorsal side of hind femur. In males, the harp, chord1, chord2, sub-mi, sub-c1 and surrounding veins of these structures darkish ( Fig. 2A View FIGURE 2 ). In females, basal half of Sc vein darkish ( Fig. 2B View FIGURE 2 ). When alive, body overall green, middle tibiae, hind tibiae, all tarsi and cercus reddish brown ( Fig. 1 View FIGURE 1 ).

Variation.

Spurs and spines on hind tibiae are varied in number. Different from the holotype, spines in some individuals exist from the first dorsal spur to the last one.
