Anterior margin of pronotum nearly straight, posterior margin obtusely rounded (Fig. 3B); lateral lobes longer than high, humeral sinus indistinct (Fig. 3C).
Ventral margins of all femora without spines. Procoxae with 1 long spine. Protibiae and mesotibiae with 4 pairs of spines and 1 pair of apical spurs on ventral surface; protibial tympana opened on both sides, ovoid. Apices of genicular lobes of postfemora with 1 small spine on each side; posttibiae with 34–35 internal spines and 29 external spines on dorsal surface, ventral surface with 2–3 pairs of small spines, apices with 1 pair of dorsal spurs and 1 pair of ventral spurs.
Tegmina covered by pronotum; hind wings absent. Lateral margins of ninth abdominal tergite obviously protruding backwards; tenth abdominal tergite triangular in dorsal view, the lateral margins of subapical area faintly contracted, apex with small triangular concavity (Fig. 3G). Cerci short and conical. Ovipositor strongly curved upwards, dorsal margins slightly serrate, ventral margins smooth, apices acute (Fig. 3I). Subgenital plate wider than long, the lateral margins obviously narrowing from basal to apical area, posterior margin concave, the lateral lobes rounded (Fig. 3H).
Coloration. Body yellowish green. Eyes black brown. Disc of pronotum with a longitudinal brown brand along the midline which widened at posterior margin, outer margins with 1 black brown stripe and a yellow stripe on each side (Fig. 3B).
