Eye ellipse, vertical diameter 1.4 times horizontal diameter and 1.8 times subocular furrow. Antennae filiform, length of segment 3.4 times width in the middle. Median keel of pronotum cut by hind transverse sulcus only, three transverse sulci are distinct, hind transverse sulcus placed after middle part, prozona 1.2 times metazona in length; lateral carinae almost parallel in prozona and indistinct in metazona. Interspace of mesosternum narrow, length 1.2 times minimum width. Both metasternal lobes separated. Tegmina developed, extending over the end of abdomen, apical part rounded, median vein area without intercalary vein, maximum width of cubital area equal maximum width of median area, cubital area without intercalary vein. Hind femur robust, dorsal carina smooth, length 4.5 times its maximun width, knee lobe rounded at apex. Hind tibia with 10 spines on outer and 11 spines on inner sides, outer apical spine absent. Arolium of hind tarsus larger, reaching the apex of claw. Tympanum developed. Cercus conical, reaching the end of epiproct. Subgenital plate short, conical, apex rounded. Epiphallus showing as Fig.12.

Female ( Figs. 1–5 ) Body of medium size. Head large, shorter than pronotum. Frons extremely oblique in lateral view. Eyes oval, longitudinal diameter 1.6 times its horizontal diameter and subocular furrow. Prozona 1.2 times metazoan in length. Length of interspace between mesosternal lobes 1.2 times its minimum width; both metasternal lobes separated. Tegmina developed, reaching apex of abdomen, apex rounded, maximum width of medial area equal to cubital area; medial area without intercalary veins. Wings equal tegmina in length. Hind femur symmetrical, length 4.6 times its width, upper and lower median carinae smooth, apex of lower lateral genicular lobes rounded. Outer side of hind tibia with 10 spines, inner side with 11 spines; outer apical spine absent. Ovipositor stubby, length of upper valve 2.1 times its width. Cerci long conical, apex pointed. Length of subgenital plate 1.8 times its width, posterior margin prominent in the middle.

Body greenish brown. Postocular band dark, wider, backward to hind margin of pronotum. Tegmina dark brown. Hind femur greenish brown, with a black ring near knee, knee black. Hind tibia dark brown, with a pale ring near base. Hind tarsus yellowish brown.

Measurement (mm): Length of body: ♂ 23.0–23.5, ♀ 31.9–34.5. Length of tegmen: ♂ 20.0–20.4, ♀ 24.7–26.5. Length of hind femur: ♂ 15.5–16.5, ♀ 19.0–20.5.

The new species is similar to C. n. nigrocornis Walker, 1870. The major differences are listed in Table 1. Etymology: The specific epithet is named for the type locality Jianfengling Mountain.
