Head ( Fig. 5 A–D) triangular in dorsal view, without distinct marks; postclypeus longer than vertex; apex of vertex with tuft of hairs; compound eye black; ocellus ochraceous. Distance between lateral ocellus and corresponding eye slightly shorter than distance between lateral ocelli. Rostrum black, extending to apex of mid coxae.

Pronotum ( Fig. 5 C) without carina or groove except for grooves of inner area. Mesonotum ( Fig. 5 C) slightly narrower than pronotal collar; cruciform elevation black.

Legs ( Fig. 5 G) mostly black; fore femur with primary spine prostrate; secondary and subapical spines erect, sharp and short.

Fore wing ( Fig. 5 A–B) hyaline in apical half; basal membrane red; basal half of fore wing yellowish, translucent, with fuscous spot on outer side of nodal line which connected with costal margin; or basal half entirely fuscous, opaque, without spots; veins of fore wing fuscous or orange in basal half and fuscous in apical half. Hind wing ( Fig. 5 A–B) hyaline, basal part red.

Abdomen ( Fig. 5 A–B) cylindrical, a little longer than distance from head to cruciform elevation, not extended laterally in dorsal/ventral view. Timbal cover ( Fig. 5 F) small, wide and somewhat triangular, with apex rounded; timbal largely exposed, with eight ribs and seven intercalary ribs, caudal five ribs fused at base. Ventral surface of body black, shining metallic blue. Male operculum ( Fig. 5 E) black, comparatively short, falcate, extending to anterior margin of seternite II; opercula widely separated from each other.

Male genitalia ( Fig. 6 A–D). Pygofer barrel-shaped in ventral view; dorsal beak long, protruding upwards in lateral view; basal lobe of pygofer short, with apex acute; upper lobe of pygofer in lateral view long, slightly curved downwards apically; distal shoulder broadly rounded and convex submarginally, forming a distinct submargin in lateral view. Clasper with median clasper process very long, narrowed and curved inwards apically in ventral view; lateral clasper lobe short, broadened and rounded in ventral view. Prominent lobe-like process at both sides of base of aedeagus small. Aedeagus with seven long spine-like processes apically and subapically; apical process on right side longest and curved upwards; other processes curved ventrally in lateral view. Posterior margin of sternite VII rounded.

Female pygofer acute in dorsal view; dorsal beak long, posterior margin of sternite VII incised at middle.

Measurements (103, 20Ƥ) (in mm). Length of body: 3 15.0–16.5, Ƥ 15.0–19.0; length of fore wing: 3 16.5–17.0, Ƥ 15.5–19.0; width of fore wing: 3 5.0–5.5, Ƥ 4.5–6.5; width of head including eyes: 3 4.0–4.5, Ƥ 3.5–5.0; width of pronotum (including pronotal collar): 3 6.0–6.5, Ƥ 6.0–7.0; width of mesonotum: 3 5.0–5.5, Ƥ 4.5–6.0.

Biology. This species is widely distributed in low mountains of Palaearctic Region and Oriental Region. Adults appear from May to July. According to Kato (1956), adults are slow in movement, and males often sing on leaves of shrubs, but sometimes stay on weeds. According to Hayashi (1976), adults of this species settle on higher twigs of broad-leaved trees, rarely on leaves of grasses.

Variations. Basal half of fore wing with various translucent or opaque stripes.

Distribution. China ( Taiwan, Guangdong, Guangxi, Yunnan, Fujian, Zhejiang, Hunan, Jiangxi, Sichuan), Myanmar, India.
