Material examined. Holotype (♂). TAIWAN: Taichung City, Huping, Wuling-Chika, Mt. Hsueshan (1900–2400 m alt.), 24.36, 121.31, 13 Aug 1990, M. Tomokuni (NSMT) (AMNH _ PBI 00378773). Paratypes: TAIWAN: Taichung City, Huping, Yunlong, Shanchuang, 2500 m alt., UV lighting, 4 Aug 1990, M. Tomokuni, 1♂ (NSMT); Huping, Szuyuan–Yushong, 1900–2300 m alt., 1 Aug 1990, M. Tomokuni, 1♀ (NSMT).

Diagnosis. Recognized by its generally pale green, moderate-sized, elongate, subparallel-sided body (Fig. 5J– K); darkened apex of clypeus (Fig. 5L); narrow brown macula at apex of corium; reddish brown apical 1/2–1/3 of metafemur; projected phallotheca with a subapical fold (Fig. 20O); and narrow, spatulate vesical ventral sclerite with a small, hooked process at apex (Fig. 20O). A combination of these characters enables this new species to be distinguished from other Asian congeners.

Description. Body elongate-oval, subparallel-sided, moderate in size; basic coloration pale green; dorsal surface with uniformly distributed, pale, simple, short, reclining-semierect setae. Head pale brown, weakly tinged with red, shining; basal transverse carina of vertex slightly narrower than pronotal collar. Antenna pale brown; apex of segment II, entire III and IV brown. Labium pale reddish brown, slightly exceeding apex of mesocoxa, shorter than metafemur; apex of segment IV darkened. Pronotum and scutellum shining, partly tinged with red; thoracic pleura pale reddish brown; scent efferent system pale brown, subtriangular with small peritreme (Fig. 20H). Hemelytra shiny pale green; clavus more or less tinged with brown; apex of corium with a brown, narrow macula; membrane smoky brown, speckled with semitransparent, pale portions. All coxae creamy pale brown; legs pale brown; basal 1/2–1/3 of metafemur reddish brown (Fig. 5L); apex of each tarsomere III darkened; meta-tarsomere II slightly longer than III (Fig. 20I); pretarsal structure as in Fig. 20J; parempodia relatively short. Ventral side of abdomen yellowish green.

Male genitalia (Figs. 12A–C, 20K–O): Sensory lobes of parameres moderately produced at apex (Figs. 12A– B, 20L–N); right paramere with hooked hypophysis (Fig. 12B, 20N); vesica with weakly curved spiculum and spatulate, narrow ventral sclerite (Figs. 12C, 20O).

Female genitalia: Not examined.

Measurements: See Table 1.
