DESCRIPTION (Chinese specimens). MALE. Body medium for the genus, robust. Head between antennal cavities low, about 2.4 times as broad as scape ( Fig. 1 ). Eye elongate, about as long as scape; ocelli inconspicuous; scape faintly longer than predicel. Face with a minute, undulating carina ( Fig. 3 ). Pronotum with surface relatively smooth ( Figs. 2, 3 ). Fore coxae with a small, sharp spine. Fore and middle tibiae with 5 spurs on each side of ventral surface, the apical of which is minute. Hind femora with 6–9 inner and 11 outer small spines on ventral surface, outer ones obviously longer than inner ones; hind tibiae faintly arcuate, dorsal surface with 6 pairs of smaller spines, apices with 2 minute dorsal spurs and 4 ventral spurs. Tegmina surpassing the apices of hind femora. Hind wings faintly longer than tegmina. Abdominal stridulatory pegs obviously smaller, present as a single row on second abdominal tergite and a widely spaced, parallel double rows on third abdominal tergite. Lateral margins of apex of ninth abdominal tergite with a pair of hooks which pointed upwards and inwards, between of the hooks deeper concave; posterior margin of tenth abdominal tergite with a pair of tuberculate processes in middle, almost between above-mentioned hooks ( Figs 4–5, 6 ). Cerci elongate, projecting well beyond apex of abdomen. Subgenital plate broad, posterior margin with a shallow concavity in middle ( Fig. 6 ). Styli slender, conical, apices obtuse, located on lateral parts of subgenital plate near apex.

FEMALE. Body faintly larger, appearance is similar to that male ( Figs. 8–10 ). Posterior margin of seventh abdominal sternite with semicircular lobe, which faintly concave in middle ( Fig. 13 ). Basal area of subgenital plate broad, posterior margin of this plate triangularly concave in middle. Ovipositor short, strongly upcurved, with dorsal and ventral margins smooth, and with apices subacute ( Figs. 11–12 ).

COLORATION. Body brown. Head pale brown, its dorsum with 3–5 small blackish spots, its face with 4 pairs of small black brown spots; inner margins of scape and pedicel, and basal flagellar segments blackish. Pronotum

black brown, the other segments of flagellum pale brown with black posterior parts of disc and lateral lobes, pronotal disc with 4 pairs of small dark brown spots. Tegmina brown, hind wings tawny. Distal area of femora, basal area and distal area of fore and middle tibiae, and all spines on hind femora black. Apices of hooks on male ninth abdominal tergite black; apical part of processes of tenth abdominal tergite blackish brown.
