Description. Body black, with following parts ochraceous: apical half of postclypeus, lorum, spots on fore femur, mid femur, mid tibia, hind femur, hind tibia and tarsus, sternites III–VII in males and 9th abdominal segment in female.

Head ( Fig. 13 ) black, with golden hairs in dorsal view; postclypeus as long as vertex in dorsal view; compound eye fuscous; ocellus ochraceous. Distance between lateral ocellus and corresponding eye as long as distance between lateral ocelli. Anterolateral margin of vertex and antenna ochraceous; rostrum fuscous, extending to apex of mid coaxe.

Pronotum ( Fig. 13 ) black, with golden hairs. Mesonotum ( Fig. 13 ) black, with golden hairs; cruciform elevation with dense short golden hairs on both sides.

Fore wing ( Fig. 13 ) fuscous basally, hyaline apically; hind wing ( Fig. 13 ) hyaline, veins fuscous. Variation of wing infuscation as shown by Hayashi (1976).

Abdomen ( Fig. 13 ) black, cylindrical, with short golden hairs and forming longitudinal golden fasciae medially; terga VI–VII with silvery tuft of hairs laterally in dorsal view. Timbal cover small and triangular; timbal with seven ribs and six intercalary ribs, caudal five ribs fused at base, 6th rib independent, 7th rib very small. Ventral surface of abdomen mostly black, with silver white hairs. Male operculum short, falcate.

Male genitalia. Pygofer dorsal beak long, protruding upwards in lateral view; upper lobe of pygofer short and stout, curved upwards basally in lateral view. Clasper with median clasper process long, digitate and curved inwards; lateral clasper lobe short and rounded in ventral view. Aedeagus with five long spine-like processes apically and subapically, which are all ventrally curved inwards in lateral view.

Female with ovipositor sheath extending to apex of abdomen; posterior margin of sternite VII with deep incision.

Measurements (in mm). Body length: 3 16.0, Ƥ 14.5; fore wing length: 3 22.0, Ƥ 20.0. (According to the measurments of Matsumura, 1907).

Material examined. No specimen available.

Biology. This species is distributed from lowlands to mountainous areas up to about 1,100m in altitude. Adults appear from April to August, often found on leaves of low shrubs ( Hayashi, 1976; Lee & Hayashi, 2004). Males often sing on leaves of shrubs. According to Hayashi (1976), copulation is performed in end-to-end style mainly on leaves of trees.

Distribution. China ( Taiwan).

Remarks. There were two specimens (13, 1Ƥ) of this species from Taiwan deposited in NWAFU ( Chou et al., 1997), but a search for them was unsuccessful. However, we took photos of the specimens of this species deposited in BMNH, and redescribe this species according to those and the descriptions of Matsumura (1907), Hayashi (1976) and Chou et al. (1997).
