Diagnosis. This new species differs from Homogryllacris brevipenna Du, Bian & Shi, 2016 by margins of pronotum darker, disc with 1 pair of black spots ( Fig. 3C View FIGURE 3 ); posterior margin of male subgenital plate with wider and shallower median concavity ( Fig. 3L View FIGURE 3 ), the lateral lobes small and triangular with external margin short, faintly concave ( Fig. 3H View FIGURE 3 ). While the latter species has the median concavity of subgenital plate deeper and narrower, the lateral lobes triangular, apices acute ( Du et al., 2016: Fig. 2E, G View FIGURE 2 ). It differs from Homogryllacris biloba (Bey-Bienko, 1957) by the black color patterns of pronotum and the shape of male subgenital plate.
Description. Male. Body medium-sized. Face with scattered impressed dots ( Fig. 3A View FIGURE 3 ). Fastigium verticis wider than scape. Fastigium frontis separated from fastigium verticis by a very fine suture ( Fig. 3A View FIGURE 3 ). Ocelli distinct.
Pronotum projected slightly in the median area of anterior margin, posterior margin nearly straight ( Fig. 3C View FIGURE 3 ); lateral lobes longer than high ( Fig. 3B View FIGURE 3 ).
Fore coxae with 1 spine. Fore and middle femora unarmed on ventral surfaces; hind femora with 5–6 internal and 3–6 external spines on ventral surface. Fore and middle tibiae with 5 pairs of ventral spurs, including 1 pair of apical ones, middle tibiae with 1 internal spine on dorsal surface ( Fig. 3E View FIGURE 3 ); hind tibiae with 4 internal and 6–7 external spines on dorsal surface, apices with 1 pair of dorsal spurs, 1 pair of subapical ventral spurs and 2 pairs of ventral spurs.
Tegmina reduced, extending only to the middle area of metanotum ( Fig. 3D View FIGURE 3 ). Second and third abdominal tergites each with 2 rows of stridulatory pegs ( Fig. 3F View FIGURE 3 ). Eighth abdominal tergite slightly prolonged. Ninth abdominal tergite prolonged backward and ventrad, triangular in dorsal view, posterior margin with large concavity ( Fig. 3G View FIGURE 3 ). Tenth abdominal tergite with 1 pair of depressed processes, crossing each other in basal area, the other parts arched curved ventrad; apical areas sclerotized, apices acute, its directing forward ( Fig. 3G, H View FIGURE 3 ). Subgenital plate longer than wide, basal margin nearly straight, the lateral margins subparallel, posterior margin with 1 large median concavity, the lateral lobes small and triangular with the internal margin obliquely straight and the external margin shorter and arched ( Fig. 3L View FIGURE 3 ). Styli incurved, inserted at apico-lateral angles of subgenital plate ( Fig. 3L View FIGURE 3 ).
Female. Unknown.
Coloration. Body yellowish brown. Antennal cavities with black margins ( Fig. 3A View FIGURE 3 ). Fronto-clypeal suture with 1 pair of black spots ( Fig. 3A View FIGURE 3 ). Fastigium frontis with 1 pair of circular black spots, fastigium verticis with 1 transversal black stripe ( Fig. 3A View FIGURE 3 ). Dorsal surface of head with three black spots, forming semicircular. Pronotum with black margins, disc with 1 pair of oblique stripes ( Fig. 3C View FIGURE 3 ). Dorsal surface of mesonotum, metanotum and abdomen black. Apical areas of femora and tibiae reddish brown ( Fig. 3E View FIGURE 3 ). Tegmina brown ( Fig. 3D View FIGURE 3 ).
