ÑPƋÞ烟ẽȃ

Figs. 28–29

Description. Male. Head ovoid. Face with scattered impressed dots. Fastigium verticis slightly wider than scape, fastigium frontis separated from fastigium verticis by a fine suture ( Fig. 28A ). Ocelli distinct, median ocellus larger than lateral ocelli.

Fore coxae with 1 small spine. Fore and middle femora unarmed on ventral surfaces, tibiae with 4 pairs of spurs and 1 pair of apical spurs on ventral surfaces. Hind femora damaged, tibiae with 6 pairs of spines and one pair of apical spurs on dorsal surface, ventral surface with 1 subapical spur and 2 apical spurs on each side.

Wings far surpassing the apex of abdomen. Tegmina ( Fig. 28C–D ): radius with RS branching little before middle area of tegmen, both forked; media anterior free from base but leaning on radius, media posterior absent; cubitus anterior and cubitus posterior undivided, but the latter fused with An 1 in short distance at base; with 4 anal veins, the last two with common stem at base.

Second and third abdominal tergites without stridulatory pegs ( Fig. 28E ). Eighth abdominal tergite prolonged ( Fig. 28F ). Ninth abdominal tergite split at apical half and prolonged into a short and incurved spine, in situ spines crossing each other ( Fig. 28G ). Subgenital plate wider than long, lateral margins convex, posterior margin arched concave ( Fig. 28H ). styli cylindrical, longer than subgenital plate, inserted at apico-lateral angles.

Female. Unknown.

Coloration. Body yellowish brown. Genae, mandibles and ventral area of labrum black ( Fig. 28A ). Dorsal surface of head with blackish spot along the middle area. Internal margins of antennal sockets black. Margins of pronotum brown with black stripe which extending the anterior margin and basal half of ventral margins of lateral lobes ( Fig. 28B ). Basal areas of femora and apical areas of tibiae of all legs blackish. Tegmina semi-transparent yellowish, towards base darker, veins brown ( Fig. 29C–D ).

Measurements (mm). Male: BL 30.8, PL 7.8, TL 31.0, HFL 18.0.

Material examined. Holotype: male, Dulong, Maguan , Yunnan, July 27, 2021, coll. by Wei Bin, Xiaoyu Peng and Xun Bian . Other specimens: 2 male nymphs, other information as holotype.

Distribution. China: Yunnan (Maguan).

Discussion. The new subspecies differs from Capnogryllacris xichou xichou Peng & Bian, 2021 by: posterior margin of male subgenital plate indistinct concave; black spots of pronotum wide and with indistinct yellowish spots.

Etymology. The new subspecies is named for the color of face; from Latin word “ flav ” and “ frons ”.
