Diagnosis. This new species differs from Homogryllacris bilobus ( Bey-Bienko, 1957) in the following: ventral surfaces of antennal cavities without longitudinal black stripe on each side ( Fig. 5A View FIGURE 5 ); protonal disc with one black median band and some black lateral stripes ( Fig. 5B View FIGURE 5 ); wings reaching the middle area of metanotum ( Fig. 5C View FIGURE 5 ); posterior margin of female with median concavity ( Fig. 5F View FIGURE 5 ). In Homogryllacris bilobus ( Bey-Bienko, 1957) , ventral surfaces of antennal cavities with longitudinal black stripe on each side; pronotal disc with regular black band along midline which widened at anterior and posterior margins; wings justly reaching the posterior margin of mesonotum; posterior margin of male subgenital plate with obtusely triangular concavity which wider and shallower than Homogryllacris brevipenna Du, Bian & Shi, 2016 ( Du et al., 2016: Fig. 2E View FIGURE 2 ), the lateral lobes rounded; posterior margin of female subgenital plate widely rounded, faintly concave in middle.
Description. Female. The following characters are in addition to those similar Homogryllacris unicolor ’s description. Hind femora with 3 pairs of spines on ventral surface; hind tibiae with 5 pairs of spines on dorsal surface. Wings reaching the middle area of metanotum ( Fig. 5C View FIGURE 5 ). Second and third abdominal tergites with two rows of stridulatory pegs ( Fig. 5D View FIGURE 5 ). Seventh abdominal tergite longer than other sterna, faintly furrowed along midline on ventral surface with lateral areas convex, basal area with 1 pair of copulatory depressions ( Fig. 5F View FIGURE 5 ). Intersegmental membrane between seventh sternite and subgenital plate shorter than the length of subgenital plate provided with faintly transverse folds ( Fig. 5F View FIGURE 5 ). Posterior margin of subgenital plate with triangular concavity in middle, the lateral lobes obtuse ( Fig. 5F View FIGURE 5 ). The average length of ovipositor about 0.96 times as long as body.
Male. Unknown.
Coloration. Body brown with black patterns. Face with 1 black spot in middle and 1 pair of black spots between antennal cavities; clypeo-frontal suture with 1 pair of small black spots, mandible with 1 black spot on each ( Fig. 5A View FIGURE 5 ). Internal margins and ventral margins of antennal cavities black, scape with black spots ( Fig. 5A View FIGURE 5 ). Internal margins of scape and pedicel with black spots. Fastigium verticis with 1 pair of black spots, behind these stripes with 1 black longitudinal band in middle which widening to semicircular on dorsal surface of head surrounding a black spot in middle ( Fig. 5B View FIGURE 5 ). Eyes black. Margins of pronotum black, disc with irregularly black longitudinal band along the midline ( Fig. 5B View FIGURE 5 ). Mesonotum, metanotum and dorsal surface of abdomen black ( Fig. 6B View FIGURE 6 ). Wings brownish. Ovipositor brown. Apical areas of all femora and basal areas of all tibiae brownish.
