Figs. 20–21
Description. Body large. Face with scattered impressed dots. Fastigium verticis wider than scape, fastigium frontis separated from fastigium verticis by a fine suture (Fig. 20A). Ocelli distinct, median ocellus obviously larger than the lateral ocelli.
Anterior margin of pronotum projected in the middle, posterior margin arched; lateral lobes longer than deep, anterior angle widely rounded, posterior angle rounded (Fig. 20B).
Fore coxae with 1 spine. Fore and middle femora unarmed, hind femora with 19–20 internal and 10 external spines on ventral surface. Fore and middle tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces; hind tibiae with 6–7 pairs of spines and 1 pair of apical spurs on dorsal surface, ventral surface with 1 subapical and 2 apical spurs on each side.
Tegmina surpassing the ninth abdominal tergite and slightly reaching the apical third of hind tibiae (Fig. 21A– B). Tegmina (Fig. 21C–D): radius releases RS little before middle area of tegmen, both forked; media anterior free from base; cubitus anterior at base single branched, makes a curvature and receives a short connection branch from MA, then again divides into MP and CuA; cubitus posterior undivided, free throughout; with 4 anal veins, the last two with short common stem.
Second and third abdominal tergites without stridulatory pegs (Fig. 20D). Eighth abdominal tergite prolonged and curved downwards (Fig. 20E). Ninth abdominal tergite with deep furrow along the midline, on both sides with a globular swelling that has a short black spine on ventral margin, in situ crossing each other just behind base (Fig. 20G). Cerci slender, apices subacute. Subgenital plate wider than long, lateral margins convex, posterior margin angularly concave (Fig. 20H). Styli stout, inserted on the apico-lateral angles.
Female. Unknown.
Coloration. Body yellow brown. Genae, mandibles and ventral area of labrum black (Fig. 20A). Pronotum with a pair of black stripes which extending the anterior margin of lateral lobes (Fig. 20B). Tegmina semi-transparent yellowish, towards base darker. Spines of all tibiae black or slightly lighter.
Measurements (mm). Male: BL 36.0, PL 7.0, TL 31.0, HFL 19.0.
Material examined. Holotype: male, Jianfengling, Ledong, Hainan, September 16, 2021, coll. by Yue Zha.
Distribution. Hainan (Ledong).
Discussion. The new species differs from Capnogryllacris nigromarginata nigromarginata (Karny, 1928) in: genae black, pronotum with black stripes not connecting each other and margins brown (Fig. 20B); dorsal surface of abdomen without seta, the spines of male ninth abdominal tergite short.
Etymology. The new species name is from Latin word “ sequestr ” referring to the stripes of pronotum on connected.
