Coloration. Body generally brown, powdered ( Fig. 4A View FIGURE 4 ). Vertex with lateral marginal carinae and disc white ( Figs 4A, B View FIGURE 4 ). Frons white, with lateral marginal carinae white, in lateral view, genae white, each with a small dark spot at middle and another one at part adjacent to clypeus ( Figs 4C, D View FIGURE 4 ). Clypeus brown in disc and darker in lateral parts, with a longitudinal median carina yellowish, and two lateral ones white ( Fig. 4C View FIGURE 4 ). Rostrum dark brown. Eyes gray; ocelli white. Antennae yellowish ( Figs 4C, D View FIGURE 4 ). Pronotum dark brown, yellowish at middle, with some irregular yellow spots on each lateral part, margins white ( Figs 4C, D View FIGURE 4 ). Mesonotum with disc yellow in anterior part between lateral carinae and brown on other part, longitudinal median and lateral carinae white in anterior half and orange in posterior half, scutellum with posterior margin orange ( Figs 4A, B View FIGURE 4 ). Tegula gray ( Figs 4B, C View FIGURE 4 ). Tegmina generally brown and semitransparent, with almost every apical cell with a transparent spot or spots, with a large closed transparent region between MP 1 and subapical lines, screw-shaped, and another one covered clavus; veins brown to dark brown ( Figs 4A, E View FIGURE 4 ). Wings brownish and semitransparent, with four elongate, longitudinal and transparent stripes separated by veins adjacent to posterior margin; veins brown ( Fig. 4G View FIGURE 4 ). Legs white to yellowish, tarsi darker, with a black stripe on each coxa of fore and middle legs ( Figs 4C, D View FIGURE 4 ). Abdomen yellow to dark brown, with median carina yellow, and several rows of small yellow spots on tergites ( Figs 4B, D, F View FIGURE 4 ). Anal tube of male and gonostyli gray; phallic complex brown. Female genitalia yellow and brownish ( Figs 12C, D View FIGURE 12 ).

Structure. Head and thorax. Frons with lateral marginal carinae contiguous ( Fig. 4C View FIGURE 4 ). Rostrum with apical segment expanded to apex, beyond coxae of hind legs. Antennae with pedicelli about 1.4 times longer than widest part and shorter than frons, pyriform, expanded distad and slightly concave at apex ( Figs 4C, D View FIGURE 4 ). Mesonotum about 7.5 times longer than pronotum in midline, disc raised apparently, and posterior part flat, with three distinct longitudinal carinae, median carina straight and two lateral ones curved towards median carina at their middle ( Figs 4A–C View FIGURE 4 ). Tegmina narrow and elongate, about 3.7 times longer than widest part, narrowest basally and widest centrally, then slightly constricted distad, posterior margin arched, jugal margin protruded, apical margin truncated; RA 2 with two branches curved anterad; MP 3+4 forked about same level as MP 1+2 forking, and MP 3 sharply changes direction near base to parallel with MP 4, C3b long and subrectangular, MP 1 aaa forked; CuA forked before first m-cu, CuA 1 and CuA 2 fused near apex to form a common stem and then extending to posterior margin, C5 present and elongate ( Figs 4A, E View FIGURE 4 ). Metatibiotarsal formulae: 4-6-7 ( Fig. 4C View FIGURE 4 ).

Male genitalia. Anal tube relatively short, and slightly grooved, with apex extending to same level as apex of gonostylus, in dorsal view, subfusiform, widest at middle, slightly constricted distad, and blunt at apex, with anal stylus at middle, epiproct wide and oval, paraprocts long and oval ( Fig. 5D View FIGURE 5 ); in lateral view, relatively straight, widest and convex dorsocaudad in basal third, slightly inclined ventrad at apex, with ventral margin roundly concave in apical quarter and straight in other part, dorsolateral margin slightly elevated from basal third to subapical part ( Figs 5A, B View FIGURE 5 ). Pygofer narrow, in lateral view, widest ventrally, anterior margin slightly convex at dorsal quarter, posterior margin smooth and slightly arched caudad, with laterodorsal angles very slightly protruded ( Figs 5A, B View FIGURE 5 ), in ventral view, venter wide rectangular, posterior margin with medioventral process moderate and pointed ( Fig. 5C View FIGURE 5 ). Gonostyli narrow and long, in dorsal view, wide basally, constricted distad, acute and incurved apically ( Figs 4F View FIGURE 4 , 5E View FIGURE 5 ); in lateral view, wide basally, slightly constricted to subapical part, upcurved and truncated obliquely apically, dorsal and ventral margin relatively parallel and straight; with a significant internal auricular process inside near dorsal base, densely covered setae on surface, in addition, with a small hook-like process protruded outward and ventrocephalad at apex of it ( Figs 5A, F View FIGURE 5 ). Phallic complex short and stout, in dorsal view, periandrium wide in most part except for narrow at extreme base and apex, left margin convex right-angled at distal side of middle and forming into a lobate process (P 4) dorsad, right margin sinuate, apical margin bifurcated and folded dorsad, forming into two lobate processes (P 1a on left and P 1b on right) ( Fig. 5G View FIGURE 5 ); in lateral view, periandrium very wide, strongly expanded triangularly, dorsal margin slightly sinuate and ventral margin strongly convex angularly in median, ventral basal angle not protruded, P 1a directed dorsad and blunt acute at apex, P 1b larger than P 1a, directed dorsocephalad and round at apex, P 4 subtriangular ( Figs 5H, I View FIGURE 5 ); with other three processes (except for P 1a, P 1b and P 4), from apex to base: a moderately long and acicular process (P 2) at middle of apex, directed dorsocephalad; a long process (P 3) on left of apex, wide at base, gradually tapered distad and directed dorsocephalad; a small and spinous process (P 5) located at distal side of middle on ventral margin, directed dorsocaudad; endosoma not obvious ( Figs 5G–I View FIGURE 5 ).

Female genitalia. Pygofer with laterodorsal tergal processes absent; ventrosternal processes relatively weak; sternal plate with paired gonocoxae VIII in a V-shape. Gonocoxa IX developed and C-shaped, dorsolateral angle slightly convex. Gonoplac laminated, in caudal view, blunt acute at base, broadest about basal third, then constricted distad, and truncated at apex ( Figs 1B View FIGURE 1 , 12C, D View FIGURE 12 ).

Material examined. 4♂ 6♀ ( NWAFU), Nansan , Zhennan, Yunnan Province, China, 400m, 7 July 2007, coll. Wei Cong. 4♂ 15♀ ( NWAFU), Taoyuanyu , Wuyi Mountain, Fujian Province, China, 600m, 18 Aug 2008, coll. Wang Manqiang.

Remarks. This species is identified based on the following features: pygofer of male with the pointed medioventral process, anal tube of male not turned ventrad at apex, gonostylus sharply pointed and turned inward and upward. The tegmina and phallic complex are first illustrated.
