Holotype: male, Nonggang, Longzhou, Guangxi, 27 Jul. 2011, coll. Xun Bian. Paratypes: 18 males and 5 females, Nonggang, Longzhou, Guangxi, 25–30 Jul. 2011, 2 males, Sanlian, Longzhou, Guangxi, 3 Aug. 2011, coll. Xun Bian.

Description. Male. Size large. 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 protruding. Disc of pronotum with cylindrical prozona, posterior area of metazona subflat and shouldered, anterior margin straight, posterior margin obtusely rounded, meso-transverse sulcus V-shaped, at about 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 48 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 4–5 external dorsal spines, 5–6 ventral spines on each side; mesofemur with 4–6 external ventral spines, mesotibia with 7–13 internal dorsal and 7–8 external dorsal spines, 7 internal ventral and 10 external ventral ones; postfemur with 7–8 ventral spines on each side, posttibia with 32 internal dorsal and 29 external dorsal spines, 14 internal ventral and 21 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 a central process prolonged, lateral sides parallel at apical half, shallow, longitudinal groove dorsally, posterior margin slightly incised in middle, both lateral processes short; cerci long, conical, upcurved; epiproct protruding ventrally, like a pocket-shaped hat inverted in lateral view, a stout dorsal spine on apex, some bristles arounded it ( Figs. 31 , 55 ). Subgenital plate broad at base and then constricted suddenly, lateral sides upcurved at basal third, ventral surface with distinct central and lateral carinae, apical lobes narrow, longer than half of its length, upcurved strongly in lateral view, both inner margins arched gently inwards, short styli bulged ( Fig. 33 ).

Female. Appearance is similar to male. Subgenital plate large, almost rectangle, longer than wide, apex notched deeply, with apical lobes trapeziform, lateral margins parallel, posterior margin approximately straight with minute serrations ( Figs. 65 , 72 ); cerci conical, incurved; ovipositor equally broad throughout, curved upwards, dorsal valvula with apex truncated, slightly concave, about 20 blunt teeth, ventral margin with some blunt teeth near apex, valvulae with rows of granules on surfaces at apical half.

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 cercus tip dark brown; epiproct brown and stout dorsal spine of epiproct black and shiny. Ovipositor with apical one-third part brown to black.

Measurements (mm). Length of body: male 27.0–32.5, female 31.0–31.5; length of pronotum: male 6.5–7.0, female 7.0–7.2; length of tegmen: male 52.5–56.0, female 50.0–51.5; length of body and wings: male 63.9–68.1, female 62.9–64.8; length of profemur: male 11.0–11.2, female 8.9–9.0; length of mesofemur: male 14.3–14.5, female 13.0–13.2; length of postfemur: male 34.0–35.5, female 33.0–33.5; length of protibia: male 12.5–12.8, female 11.3–11.6; length of mesotibia: male 17.4–17.6, female 15.3–15.5; length of posttibia: male 39.0–39.2, female 39.0–39.2; length of ovipositor 12.5; width of ovipositor 3.5.

Etymology. The name of the new species refers to the characteristic epiproct protruding ventrally, like a pocket-shaped hat inverted.

Discussion. The new species is slightly similar to S. voluptaria ( Carl, 1914) , but distinctly distinguished from the latter in: male epiproct pocket-shaped with a stout apical spine.

Distribution. China (Guangxi).
