Holotype: male, Mao’ershan, Xing’an, Guangxi, 7 Aug. 2006, coll. Fu-Ming Shi. Paratypes: 1 male, Sijianshan, Rongshui, Guangxi, 31 Aug. 2001, coll. Fu-Ming Shi; 1 male, Bawangling, Changjiang, Hainan, 3 Aug. 2007, coll. Hui Zhai; 1 male, Yinggeling, Baisha, Hainan, 8 Nov. 2009, coll. Fu-Ming Shi.

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 outstanding. Disc of pronotum with cylindrical prozona, posterior area of metazona subflat and slightly 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 at about middle of tegmina, bifurcated. Left tegmen with stridulatory vein broadened and bulging, file with about 55 teeth regularly arranged, right tegmen with a small transparent area. Hind wings longer than tegmina.

Procoxa with a spine. Profemur with 4–6 internal ventral spines, protibia with 5 internal ventral and 4 external ventral spines; mesofemur with 4 external ventral spines, mesotibia with 5 internal dorsal and 1 external dorsal spines, 7 internal ventral and 12 external ventral ones; postfemur with 7–8 ventral spines on each side, posttibia with 37 internal dorsal and 32–34 external dorsal spines, 10–11 internal ventral and 20 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 central process narrowing; cerci conical, rather thick at base, apical third upcurved; epiproct small, with a thin apical projection on dorsal margin and a long, stem-shaped projection originated on ventral surface, upcurved strongly, covered with bristles on apical area ( Figs. 29 , 53 ). Subgenital plate broad at base and lateral sides upcurved at basal third, ventral surface with distinct central and lateral carinae, apical lobes longer than half of its length, upcurved gently in lateral view, both inner margins arched inwards, styli short ( Figs. 27, 30 ).

Coloration. Body green. Costal vein white and anterior edge black. All spines on femora dark 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 22.0–26.0; length of pronotum 6.0–6.3; length of tegmen 40.5–48.0; length of body and wings 51.5–60.0; length of profemur 7.0–8.7; length of mesofemur 10.6–12.5; length of postfemur 28.0–30.0; length of protibia 9.3-9.5; length of mesotibia 12.0-12.5; length of posttibia 31.5–33.5.

Etymology. The name of the new species refers to epiproct possessing a long, stem-shaped projection.

Discussion. The new species is slightly similar to S. longifissa ( Matsumura & Shiraki, 1908) , but distinctly distinguished from the latter in: male epiproct with a thin apical projection on dorsal margin and a long, stemshaped projection originated on ventral surface, densely covered with bristles on apical area, subgenital plate with apical lobes slightly longer than half of its length.

Distribution. China (Guangxi, Hainan).
