Diagnosis. The new species differs from other species of Capnogryllacris in: head red ( Figs. 1A View FIGURE 1 , 3A View FIGURE 3 ), pronotum with black margins which widened at anterior and posterior margins ( Figs. 1B View FIGURE 1 , 3B View FIGURE 3 ); basal area of tegmina with large black spots surrounding an orange spot in the middle ( Figs. 2 View FIGURE 2 , 4 View FIGURE 4 , 5 View FIGURE 5 ); spines of male ninth abdominal tergite only crossed at subapical area, subgenital plate with a triangular concavity at posterior margin ( Fig. 1H View FIGURE 1 ); female subgenital plate with medial grooves narrower separated from each other at basal area, posterior margin bilobate ( Fig. 3E–G View FIGURE 3 ).

Description. Male. Large species. Face ovoid with sparse punctures ( Fig. 1A View FIGURE 1 ). Fastigium verticis wider than scape. Apical segments of maxillary palpi slightly longer than subapical ones, apices faintly swollen ( Fig. 1A View FIGURE 1 ). Apical segments of labial palpi obviously swollen. Ocelli distinct. Anterior margin of pronotum slightly projected, posterior margin arched; anterior angle of lateral lobes rounded, posterior angle slightly extending downwards ( Fig. 1B View FIGURE 1 ). Humeral sinus indistinct. Fore coxae with 1 spine ( Fig. 1C View FIGURE 1 ). Fore and middle femora unarmed on ventral surfaces; hind femora ventrally with 8–11 internal and 7–8 external spines. Fore and middle tibiae with 5 pairs of ventral spurs, including 1 pair of apical ones; hind tibiae with 5–6 pairs of spines on dorsal surface, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Second and third abdominal tergites with few largely reduced, indistinct stridulatory pegs or not ( Fig. 1E View FIGURE 1 ). Eighth abdominal tergite prolonged. Ninth abdominal tergite globular, with a shallowly furrow in midline, basal area swollen on each side of furrow, at apex with an acute spine, its subapical area crossing each other and directing downward and forward ( Fig. 1F–G View FIGURE 1 ). Subgenital plate wider than long, posterior margin with a triangular concavity ( Fig. 1H View FIGURE 1 ); styli slightly longer than subgenital plate, inserted at apico-lateral angles ( Fig. 1H View FIGURE 1 ).

Female. Subgenital plate nearly trapezoidal; middle area of basal margin with 2 small black grooves ( Fig. 3G View FIGURE 3 ); the lateral margins of basal areas convex, then narrowing, posterior margin bilobate ( Fig. 3E–F View FIGURE 3 ). Ovipositor moderately upcurved, dorsal and ventral margins smooth, apices subacute ( Fig. 3H View FIGURE 3 ).

Wings. Tegmina justly reaching or slightly surpassing the apex of abdomen, but not reaching the apices of hind femora ( Figs. 1I–J View FIGURE 1 , 3I View FIGURE 3 ); hind wings slightly longer than tegmina. Tegminal veins ( Figs. 2 View FIGURE 2 , 4 View FIGURE 4 , 5 View FIGURE 5 ): Radius with RS branching before apical third area of tegmen, both forked near tip; media anterior free from base, then it fuses with radius, after both veins separated again; cubitus anterior at base single branched, after divides into two branches before basal third, the anterior branch makes a curvature and receives a short connection branch from MA, shortly after it divides into MP and CuA1 (sometimes they do not reach the tip of tegmen ( Figs. 2A View FIGURE 2 , 4A View FIGURE 4 , 5C, E View FIGURE 5 )), or not divided instead runs as fused MP+CuA1 till tip ( Figs. 2C View FIGURE 2 , 5A View FIGURE 5 ), the posterior branch (CuA2) undivided. Cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem.

Coloration. General color light brown ( Figs. 1I–J View FIGURE 1 , 3I View FIGURE 3 ). Head red, eyes black, ocelli pale yellow ( Fig. 1A View FIGURE 1 , 3A View FIGURE 3 ). Margins of pronotum black which extended at anterior and posterior margins, the posterior black band nearly V-shaped ( Fig. 1B View FIGURE 1 , 3B View FIGURE 3 ). Coxae with black spots, apical areas of femora and tibiae of all legs rufous ( Figs. 1I–J View FIGURE 1 , 3I View FIGURE 3 ). Tegmina yellowish brown, towards anterior and posterior margins lighter; basal area with large black spots surrounding an orange spot in middle; veins brown ( Figs. 2 View FIGURE 2 , 4 View FIGURE 4 , 5 View FIGURE 5 ). Each abdominal tergite with black band on posterior margin; each abdominal sternite with 1 pair of black spots. Apical half of female subgenital plate and ovipositor black ( Fig. 3H View FIGURE 3 ).
