Male. Body median in size. Head larger and short, shorter than pronotum. Face slightly oblique in profile. Antennae filiform, 22 segmented, length of a segment 2.5 times width in middle part. Eyes globose, vertical diameter 1.3 times horizontal diameter and 1.8 times subocular furrow. Pronotum cylindrical, anterior margin slightly concaved in middle, median keel distinct, distinctly cut by three transverse sulci, lateral keels absent, prozona 2.0 times metazona in length, hind margin excised deeply in middle. Prosternal process conical, apex rounded. Length of interspace of mesosternum 1.8 times the narrowest, lateral lobes of metasternum separated. Tegmina shorter, not reaching the hind margin of first abdominal tergite, length 3.6 times its width. Upper keel of hind femur smooth, length of hind femur 4.5 times its maximum width, the end of lower knee lobes rounded. Hind tibia with 9 spines on inner and on outer sides, external apical spine absent. Second joint of hind tarsus shorter than first joint. Tympanum distinct, big and rotundity. Tergum of terminal abdomere with longitudinal groove in middle, furculae absent. Cercus compressed, reaching tip of epiproct, basal part very wide, its maximum width 2.2 times width of middle part, apex rounded and curved to inner side. Subgenital plate short-tapered, apex acuted. Ancorae of epiphallus oblique inward, lower margin straight in the middle. Phallic complex with short apodemes.

Female. Body more robust. Vertical diameter of eyes 1.5 times horizontal diameter and subocular furrow. Prozona 1.9 times metazoan in length. Tegmina shorter, not reaching hind margin of the 1st abdominal tergite, length 2.8 times its width. Length of hind femur 5.2 times its maximum width. Cercus short-conical, not reaching end of epiproct. Ovipositor valve thick at base, apex acute, with small teeth on outer margin.

Coloration. Body brown. Antennae yellowish-brown. Pronotum yellowish-brown, with a black longitudinal band along median keel. Postocular band black relatively straight, backward to pronotum and abdomen. Tegmina brown. Hind femur of male yellowish-brown, end black, part green in female. Hind tibia blue, base black. Abdomen yellowish-brown, with dark broad longitudinal stripe on both sides. Subgenital plate of male brown.

Measurements (mm). Body ♂ 18.8 — 21.8, ♀ 26.0 — 28.7; tegmina ♂ 3.6 — 3.7, ♀ 4.2–4.3; pronotum ♂ 4.6 — 4.9, ♀ 6.2–6.4; hind femur ♂ 11.8 — 12.0, ♀ 13.2–14.7.
