Descriptions

Male (figs. A-C). Body median in size. Head larger and short, shorter than length of pronotum. Face oblique distinctly in profile, with sulcus throughout, contracted distinctly in the median part. Antennae ensiform, widened distinctly in the basal part, toward apices gently narrow, 18 segments, surpassing over the posterior margin of pronotum, length of a middle segment 2.5 times its width. Eyes globose, longitudinal diameter 1.5 times horizontal diameter and 1.6 times subocular furrow. Pronotum cylindrical, median keel normal, low, slightly cut by hind transverse sulcus, lateral carinae parallel nearly, the prozona is 1.5 times of metazona in length, hind margin excised slightly in the middle. The length of interspace of mesosterum equal to the narrowest, lateral lobes of metasternum separated. Tegmina abbreviated, scale, lateral. Upper keel of hind femur serrated slightly, well proportioned, length as long as 4.6 times of maximum width, the end of lower knee lobes rounded. Hind tibia with 12 spines on the inner and 11 spines outer side, external apical spine absent. Second joint of hind tarsus shorter than the first joint. Tympanum organ distinct. Epiproct with longitudinal groove in the middle. Cercus slender, reaching to the tip of epiproct, furculae absent. Subgenital plate short, conical.

Female (figs. D-F). Body larger, more robust. Antennae ensiform, 18 segments, shorter, not reaching to the posterior margin of pronotum. Longitudinal diameter of eyes 1.5 times horizontal diameter and equal to subocular furrow. The narrowest of interspace of mesosterum is 1.1 times its length. Length of the hind femur as long as 5.4 times of maximum width. Epiproct triangular, basal half part with longitudinal groove in the middle. Cercus short-conical, about reaching to the 2/3 of epiproct. Ovipositor valves short, distinctly hooked in the end, outer margin smooth.

Coloration

Males Body yellowish-brown. Antennae brown, apical three segments pale. Pronotum brown. Postocular band black, extending to the tegmina. Tegmina darker in anterior 2/3 part and yellowish-brown in posterior 1/3 part. Hind femur yellowish-brown, knee dark. Hind tibia brown, basal part dark. Abdomen and subgenital plate yellowish-brown. Females The color of body is similar to male.
