(Figs. 21–30)
Type material. Holotype: 1♀, 26 July 2011, collected by Fu-Ming SHI, SCBHU. Paratypes. 1♀, same data, type locality, SCBHU; 1♂, China, Guizhou, Mount Fanjing, 27°56’N –108°41’E, 2000m alt, 3 June 2002, collected by Shan-Yi ZHOU, SCBHU.
Type locality. China, Sichuan, Emeishan, Wannianshi, 29°31’N, 103°22’E, 1100m alt.
Description. Female (Figs. 21–29). Size small and stout and its surface coarsely, with many tubercrles and shallow depressions. Head short and not exerted above the pronotal surface, vertex is wide and its width 2.5 times the width of an eye; anterior margin of vertex nearly straight, not protruding beyond eyes, fore half of median carina conspicuous; lateral margins of vertex produced upwards, exserted above the eyes surface in profile; vertex and frontal ridge are forming a right angle, frontal ridge between eyes unseen and protruding angular between antennae in profile; width of longitudinal furrow of frontal ridge 1.5 time width of basal segment antenna. Antennae filiform, located far below the eyes, 14-segmented, mid segments 7–8 times as long as wide. Eyes globose; lateral ocelli placed in between lower margins of eyes.
Pronotum elevated and hump-shaped protuberated before shoulders, low and flat behind shoulders. Anterior margin of pronotum protruding triangular in the middle; median carina high and lamellar at the former part, low at the latter part, interrupted; lateral keels of prozona slightly constricted inwards in middle, humeral angle arcuate; dorsum of pronotum concave between shoulders and with numerous tubercles and concavities; hind pronotal process surpassing apex of hind femur and its apex concave. Posterior angles of lateral lobes produced outwards, end of posterior angles truncate, posterior margins of lateral lobes of pronotum with one concavity. Tegmina and hind wings absent. Upper and lower margins of fore femora with two large teeth; tooth of upper margins of middle femora unconspicuous and lower margins of middle femora with one large tooth. Hind femur short and stout, midkeel of upper and lower side serrated, with three large teeth behind the middle of midkeel of upper side, antegenicular and genicular denticles large and triangular; midkeel of lower side with one tooth, but unconspicuous; with 2 tubercules on outside in the middle. Outer side of hind tibia with 6–7 spines, inner side with 5–6 spines. Length of first segment of hind tarsi longer than third, third pulvillus longer than first and second, apices of first and second sharp, apices of third obtuse. Ovipositor short and stout, upper and lower valvulae with slender saw-like teeth. Length of subgenital plate equal to its width, middle of posterior margin of subgenital plate with a triangular convex.
Body dark brown. Antennae dark brown. Hind tibia black, with light ring in the base and ends.
Male (Fig. 30). Similar to female, but smaller and narrower. Subgenital plate brief cone-shaped, apex bifurcated.
Measurements (mm). Length of body ♂ 8.5, ♀ 9.0–9.5; length of pronotum ♂ 9.5, ♀ 10.0–10.5; length of hind femur ♂ 5.5, ♀ 6.0–6.5.
Diagnosis. New species is similar to Gibbotettix emeiensis Zheng, 1992 from which it differs in humeral angle arcuate (humeral angle obtuse angular in G. emeiensis); hind pronotal process surpassing apex of hind femur (hind pronotal process reaching knee of hind femur in G. emeiensis); tooth of upper margins of middle femora unconspicuous (upper margins of middle femora with two large teeth in G. emeiensis); lower margins of middle femora with one large tooth (lower margins of middle femora with two large teeth in G. emeiensis); antennae dark brown (antennae brown with light apices in G. emeiensis).
Etymology. The new species' name is derived from Latin serri and femur, meaning hind femur with three large teeth behind the middle of midkeel of upper side.
Distribution. China (Sichuan and Guizhou).
