Description. Head ( Fig. 11 A–D) reddish brown in dorsal view; apex of vertex with tuft of hairs; postclypeus very long, distinctly longer than vertex in dorsal view; compound eye fuscous; ocellus ochraceous. Distance between lateral ocellus and corresponding eye slightly shorter than distance between lateral ocelli. Rostrum black, extending to apex of mid coaxe. Face yellowish brown, gena with tuft of hairs.

Pronotum ( Fig. 11 C) red brown, with golden short hairs. Mesonotum ( Fig. 11 C) red brown, slightly narrower than pronotal collar, without distinct marks in dorsal view.

Legs ( Fig. 11 G) mostly brown; fore femur with primary spine prostrate and appressed; secondary and subapical spines erect, sharp and short.

Wings ( Fig. 11 A–B) hyaline; fore wing with wide yellowish fasciae along node line, each lateral margin of wide fasciae with brown oblique fasciae; basal cell of fore wing yellowish; apical half of fore wing hyaline.

Abdomen ( Fig. 11 A–B) red brown, cylindrical, with golden short hairs; lateral margin of tergum II with black patches in dorsal view; timbal cover ( Fig. 11 F) fuscous, with apex rounded. Timbal largely exposed, with nine ribs and eight intercalary ribs, caudal six ribs fused at base. Ventral surface of abdomen reddish brown, with golden hairs. Male operculum ( Fig. 11 E) brown, falcate; tympanum exposed; opercula widely separated from each other.

Male genitalia ( Fig. 12 A–D). Pygofer barrel-shaped in ventral view; dorsal beak long, protruding upwards in lateral view; basal lobe of pygofer very short, with apex acute; upper lobe of pygofer in lateral view stout, digitate and curved upwards; distal shoulder broadly rounded and convex submarginally, forming a distinct submargin in lateral view. Claspers in ventral view with median clasper process very long, with apex narrowed apically and curved laterally. Prominent lobe-like process at both sides of base of aedeagus a bit long. Aedeagus bifurcate subapically in lateral view; with seven long and one short spine-like processes apically and subapically, of which four processes dorsally curved inwards and the other three processes curved ventrally in lateral view. Posterior margin of sternite VII rounded.

Female pygofer distinctly wider than sternite VII in ventral view; ovipositor sheath extending to apex of abdomen; posterior margin of sternite VII deeply incised at middle.

Biology. This species is widely distributed in low mountains. Males often sing on leaves of shrubs, but sometimes are found in arbors. Some of them perch on the surface of leaves in the shade.

Variations. Ground colour of body dark brown, reddish brown to black; fasciae on basal half of fore wing with various hyaline, translucent or opaque stripes; some examined specimens with timbal cover a bit developed and fore femur with two subapical spines.

Distribution. China (Hainan, Hong Kong, Guangdong, Guangxi, Fujian, Hunan, Zhejiang, Anhui), India.
