Fore tibiae with 4 pairs of spines and 1 pair of apical spurs; hind tibiae arched curved (Fig. 1H), dorsal surface of with 5 pairs of spines on dorsal margins and the two apical spines distinct, the remainder tubercle swellings, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Second and third abdominal tergites with 2 rows of transverse stridulatory pegs on lateral margins separately (Fig. 1D). Ninth abdominal tergite globular, curved ventrad, the lateral margins forming with 1 pairs of spines, its apices spine-shaped, directing downwards and slightly inwards (Fig. 1F, G), between them wide space. Tenth abdominal tergite interrupted in the middle. Cerci short, conical, slightly upcurved, its apices obtuse (Fig. 1F).
