Figs. 18–19
Description. Male. head ovoid. Face with scattered dots. Fastigium verticis slightly wider than scape, fastigium frontis separated from fastigium verticis by a fine suture (Fig. 18A). Ocelli distinct, lateral ocelli suited on the lateral areas of fastigium frontis, and slightly smaller than median ocellus.
Anterior margin of pronotum slightly projected in the middle, posterior margin almost straight; lateral lobes longer than deep, posterior margin rounded and directing downwards, humeral sinus indicated (Fig. 18B).
Fore coxae swollen with 1 spine. Fore and middle femora unarmed, tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces. Hind femora with 13–15 internal and 9–10 external spines on ventral surface; tibiae with 6 pairs of spines and 1 pair of apical spurs on dorsal surface, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs.
Tegmina surpassing the apex of abdomen, reaching the apical area of hind tibiae. Tegmina (Fig. 19C–D): radius releases RS behind middle area of tegmen, both forked near tip. In left tegmen (Fig. 19C), media leaning on radius before basal quarter area, then releases MP, after short distance MA further divided two branches; cubitus anterior at base single branched, after divides into two branches behind basal quarter, the anterior branch makes a curvature and receives a short connection branch from MA and then remains single branched MP+CuA1 till tip (Fig. 19D). In right tegmen, media and CuA1 with common stem, and fuse a short distance with radius after then M+CuA1 divided from R; MA arises from M+CuA1 before middle area of tegmen and connects with RS and then immediately divided; MP+CuA1 divides into MP and CuA1; CuA2 arises from base and does not divided further. Both tegmina: cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem.
Second and third abdominal tergites without stridulatory pegs (Fig. 18D). Eighth abdominal tergite prolonged and apical area curved (Fig. 18E). Ninth abdominal tergite narrowing to apex with deep furrow in the middle, on both sides with a pair of oval swellings that terminate at apical margin into a compressed spine that in situ crossed each other before middle area (Fig. 18G). Cerci slender, its apices subacute. Subgenital plate longer than wide, lateral margins slightly terminating, posterior margin projected with 1 small triangular concavity in the middle (Fig. 18H). Styli cylindrical, apical half curved outward, apices obtuse; inserted on apico-lateral margin of subgenital plate (Fig. 18I).
Female. Unknown.
Coloration. Body brown. Ocelli pale. Genae bright mauve. Internal margins of antennal sockets black. Dorsal surface of head with 1 pair of black spots behind eyes (Fig. 18A). Margins of pronotum black which interrupted at the anterior margin of lateral lobes; anterior and posterior margins widened, but posterior spots extending the middle area (Fig. 18B). Dorsal surface of abdomen brownish (Fig. 18E). Apical areas of femora and basal areas of tibiae of all legs black. Spines of tibiae blackish or black.
Measurements (mm). Male BL 34.0, PL 10.0, TL 40.0, HFL 22.0.
Distribution. Guangxi (Fangchenggang).
Material examined. Holotype: male (XZ163), Fangchenggang, Guangxi, May 6, 2021, coll. by Yang Chen.
Discussion. The new species differs from Capnogryllacris nigromarginata nigromarginata (Karny, 1928) by: dorsal surface of head with 1 pair of small black spots, black spots of anterior and posterior margin of pronotum widened.
Etymology. The new subspecies name is from Latin word “ rect ” and “ spin ” referring to the spines of male ninth abdominal tergite almost straight.
