( Figure 1 View FIGURE 1 )
Description. Male. Body medium, wingless. Frons with minutely punctate. Fastigium verticis about 1.2 times as wide as scape ( Fig. 1A View FIGURE 1 ). Eyes ovoid; ocelli inconspicuous. Scape slightly longer than length of eyes, pedicel about two thirds the length of scape ( Fig. 1A View FIGURE 1 ). Apical segment of maxillary palp with apex slightly inflated. Anterior margin of pronotum produced in the middle, posterior margin truncate, lateral lobes longer than deep, ventral margin undulating, humeral sinus absent ( Fig. 1B View FIGURE 1 ). Fore coxae with 1 small spine; fore and middle femora unarmed on ventral surface. Hind femora with 7–9 pairs of spines on ventral margins; the internal spines are very large and thick, especially the 2 apical spines; the external spines are minute ( Fig. 1H View FIGURE 1 ). Fore tibiae with 4 pairs of spines and 1 pair of apical spurs; hind tibiae arched curved ( Fig. 1H View FIGURE 1 ), 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 View FIGURE 1 ). 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 View FIGURE 1 ), between them wide space. Tenth abdominal tergite interrupted in the middle. Cerci short, conical, slightly upcurved, its apices obtuse ( Fig. 1F View FIGURE 1 ). Basal margin of subgenital plate almost straight, posterior margin with 1 U-shaped concavity ( Fig. 1F View FIGURE 1 ), the lateral margins forming 2 lobes, its apices curved dorsad and slightly forward ( Fig. 1F View FIGURE 1 ).
Female. Unknown.
Coloration. Body yellowish. Eyes brown. Face and genae with black stripes, fastigium verticis black, occiput with 1 large semicircular spot on posterior margin varying from completely black reduced to two narrow stripes, between stripes with 1 median black bland which reaching the posterior margin of tenth abdominal tergite ( Fig. 1B, E View FIGURE 1 ). Basal and apical areas of scape with 1 black ring separately; pedicel with 1 black ring in the middle; flagellum black brown. Margins of pronotum, mesonotum and metanotum black ( Fig. 1B View FIGURE 1 ). Apical areas of fore and middle femora, basal and apical areas of all tibiae, and spines of hind legs black ( Fig. 1H View FIGURE 1 ); spines of fore and middle tibiae and all tarsi blackish. Apices of lateral lobes of tenth abdominal tergite brown ( Fig. 1F View FIGURE 1 ).
