( Figs. 1 , 5–6 , 17, 22–26 , 34, 40 , 49–51 ; Map 2)

Holotype: male, Taibei, Taiwan, 4 Aug. 2006, coll. Xi-Cui Du. Paratypes: 3 males, the other data same as holotype.

Description. Male. Body medium size. Fastigium of vertex narrower than scapus, apex blunt, furrowed above, moderately sloping anteriorly, and separated by a broad furrow from fastigium of frons. Occiput convex, surface smooth. Eyes ovoid, conspicuously protruding. Disc of pronotum with cylindrical prozona, posterior area of metazona subflat and shouldered, anterior margin approximately straight, posterior margin obtusely rounded, meso-transverse sulcus V-shaped slightly behind middle; paranota higher than long, ventral and posterior margins rounded together, humeral sinus distinct. Prosternum unarmed, mesosternal lobes approximately right angle and metasternal lobes rounded.

Tegmen fully developed, surpassing apex of postfemur, anterior and posterior margins slightly convex, apex rounded, C vein distinct, R vein with 3 or 4 branches, Rs vein originating slightly before middle of tegmina, bifurcated. Left tegmen with stridulatory vein broadened and bulging, file with about 56 teeth regularly arranged, right tegmen with a small transparent area. Hind wings longer than tegmina.

All femora smooth dorsally. Procoxa with a spine. Profemur with 5 internal ventral spines, protibia with 3 external dorsal spines, 5 internal ventral and 3 external ventral ones; mesofemur with 3 external ventral spines, mesotibia with 6 internal dorsal and 2 external dorsal spines, 8 internal ventral and 12 external ventral ones; postfemur with 6 ventral spines on each side, posttibia with 35 internal dorsal and 32 external dorsal spines, 16 internal ventral and 22 external ventral ones. All tibiae with apical spurs on dorsal and ventral sides. Genicular lobes with 2 apical spines. Protibia with a large, kidney-shaped outer tympanum, and conchate inner tympanum with rather wide slit-like opening.

Tenth abdominal tergum with apical area prolonged backwards, produced into a pair of forcipate lateral processes and a stout central process; cerci rather thick at base, apical third narrowing, upcurved; epiproct roundedtriangular, dorsally concaved inside, ventral surface slightly convex downwards, with a sharp spine near apex on dorsal margin, directing dorso-caudad, and sparse bristles on ventral surface ( Figs. 49–50 ). Subgenital plate broad at base and then constricted suddenly, lateral sides upcurved at basal third, ventral surface with distinct central and lateral carinae, apical portion cleft, slightly shorter than half of subgenital plate, apical lobes upcurved gently in lateral view, both inner margins arched gently inwards, styli small ( Fig. 26 ).

Coloration. Body green. Costal vein white and anterior edge black. All spines on femora brown. Processes of tenth abdominal tergum, apical part of subgenital plate and epiproct brown; cercus tip dark brown.

Female. Unknown.

Measurements (mm). Length of body 23.5–30.0; length of pronotum 6.1–6.3; length of tegmen 45.0–47.5; length of body and wings 58.5–61.7; length of profemur 8.5–9.0; length of mesofemur 13.0–13.5; length of postfemur 30.0–33.5; length of protibia 9.3– 9.5; length of mesotibia 17.8–18.2; length of posttibia 32.5–34.0.

Etymology. The name of the new species refers to epiproct with a spine on the extremity.

Discussion. The new species is slightly similar to S. tibetensis Liu & Kang, 2007 , but it differs from the latter in: male tenth abdominal tergum with central processe slightly narrow, epiproct with a sharp spine near apex on dorsal margin, and all spines on femora brown.

Distribution. China ( Taiwan).
