Figs. 3–5

Description. Body large. Fastigium verticis about one and a half times as wide as scape. Face almost smooth, with indistinct dots ( Fig. 3A ). Eyes ovoid. Ocelli distinct, the diameter of median ocellus slightly longer than the lateral ocelli.

Anterior margin of pronotum slightly projected in middle, posterior margin nearly straight; lateral lobes longer than deep, with V-shaped furrow, anterior angle widely rounded, posterior angle rounded ( Fig. 3B ).

Fore coxae with 1 small spine; fore and middle femora longer than pronotum, unarmed on ventral surfaces; fore and middle tibiae with 5 pairs of spurs on ventral surfaces, the spurs decreasing in size to minute apical ones. Hind femora with 15–17 internal spines and 8–9 external spines on ventral surface; hind tibiae with 5–7 internal spines and 6 external spines on dorsal surface; ventral surface with 1 pair of subapical spurs, apical area with 1 pair of dorsal spines and 2 pairs of ventral spines.

Tegmina surpassing the ninth abdominal tergite and slightly reaching the apical third of hind tibiae ( Fig. 5A ). Tegmina ( Fig. 5C–D ): radius with RS branching little after basal third of tegmen, both forked; media anterior free from base; cubitus anterior at base single branched, after divides before basal quarter into two branches, the anterior branch makes a curvature and receives a short connection branch from MA, then divides into MP and CuA1; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem.

Second and third abdominal tergites with fine stridulatory pegs ( Fig. 3D ). Eighth abdominal tergite projecting backwards ( Fig. 3F ). Ninth abdominal tergite split along the midline, forming 2 lateral lobes, its basal area roundedly swollen, apical area spine-shaped, crossed each other and directing ventrad and slightly forwards ( Fig. 3E ). Subgenital plate transversal broad, the lateral margins slightly narrowing to apices, basal margin almost straight, posterior margin arched concave; styli stout, cylindrical, longer than the length of subgenital plate, inserted on both sides of subgenital plate near apex ( Fig. 3E ).

Female. Body larger than male ( Fig. 5B ). Ovipositor slightly longer than male, dorsal and ventral margins smooth and narrowing to apices, apices obtuse ( Fig. 5B ). Subgenital plate in middle area of anterior margin with 1 pair of copulatory depressions with lateral margins obviously sclerotized ( Fig. 4G ).

Coloration. Body yellowish brown. Genae, mandibles and basal area of labrum black. Ocelli yellowish. Pronotum reddish brown with black V shaped stripe, the median area of the stripe with 1 yellowish longitudinal line and 1 pair of reddish spots. Spines of fore and middle tibiae brownish, dorsal spines of hind tibiae black.

Measurements (mm). Male: BL 37.0, PL 11.0, TL 48.0, HFL 25.0; Female: BL 40.0, PL 11.0, TL 41.0, HFL 25.0, OvL 26.0.

Material examined. Holotype: male (XZ139), Menglun, Mengla , Yunnan, May 13, 2021, coll. by Ruojian Yan ; Paratype: female (XZ149), the other information as holotype. Other specimen: 1 female nymph (XZ159), Guanlei, Mengla , Yunnan, May 16, 2021, coll. by Ping Yang .

Distribution. Yunnan (Jinghong, Mengla)

Discussion. Li et al. (2014) identified the species as Capnogryllacris erythrocephala borealis based on one male from Mengla. But after examining the specimens from the same place, we think which differs from the original descriptions and illustrations of the later subspecies by Gorochov (2003) in: black V-shaped stripe of pronotum not reaching the posterior margin ( Figs. 3B , 4B ), and posterior margin of male subgenital plate slightly arched concave ( Fig. 3E ). While Capnogryllacris erythrocephala borealis , black V-shape stripe of pronotum nearly reaching the posterior margin, and posterior concavity of male subgenital plate is wide and deep. The new subspecies differs from Capnogryllacris erythrocephala erythrocephala by: face darker, pronotum with 1 yellowish longitudinal line and some reddish spots, spines of male ninth abdominal tergite stout, and apex of female subgenital plate wider with deep concavity.

Etymology. The new subspecies name refers to the black stripe of pronotum with yellowish brown spots; from Latin word “ macul ”.
