Tegmina longer, reaching the hind margin of 5th abdominal tergite, apically concave in the middle, maximum width of cubital area 1.4 times maximum width of medial area. Interspace of mesosternum distinctly narrowed in the middle, length 3.1 times minimum width. Lateral lobes of metasternum separated. Upper keel of hind femur smooth, length of hind femur 6.0 times its maximum width, end of lower knee lobes angular, inner side with 103 stridulatory pegs. Hind tibia with 13 spines on inner and 14 spines on outer sides, external apical spine absent. The second joint of hind tarsus shorter than the first. Tympanum large and round. Cercus long conical, almost reaching tip of epiproct. Furculae visible, circular at apex. Subgenital plate long conical. Width of epiphallus larger than high, with indistinct projection on inner side of lateral plates.

Female: Body more robust than male. Vertical diameter of eyes 1.3 times horizontal diameter and equal to the length of subocular furrow. Prozona 1.8 times metazoan in length. Tegmina short, extending over the hind margin of 1 st abdominal tergite slightly, length 3.0 times its maximum width. Length of hind femur 5.8 times its maximum width. Cercus short-conical, not reaching the end of epiproct. Upper ovipositor valve longer, length 3.8 times maximum width, with small teeth on outer margin. Subgenital plate long, length 2.3 times maximum width.

Coloration: Body brown. Antennae yellow. Pronotum yellowish-brown. Tegmina of male without a white stripe on the fore margin at base. Tegmina of female with a black longitudinal stripe in the middle. Abdomen yellowish-brown, with a brown longitudinal stripe on both sides. Subgenital plate brown.
