Capnogryllacris jinpingensis sp. nov.

ḔṮAEợ⁂

Figures 2–3

Description. Male. Body large. Frons smooth with impressed dots ( Fig. 2A ). Fastigium verticis slightly wider than scape, the lateral margins raised. Ocelli distinct.

Pronotum projected faintly projecting in the median of anterior margin, posterior margin truncate ( Fig. 2C ); lateral lobes longer than deep ( Fig. 2D ).

Fore coxae with 1 spine. Fore and middle femora unarmed on ventral surfaces; hind femora with 15–16 internal and 6–11 external spines on ventral surface. Fore and middle tibiae with 5 pairs of ventral spurs, including 1 pair of apical ones; hind tibiae with 4–6 internal and 5–6 external spines on dorsal surface, apices with 1 pair of dorsal spurs, 1 pair of subapical ventral spurs and 2 pairs of ventral spurs.

Tegmina developed, obviously surpassing the apex of abdomen, and reaching the apices of hind tibiae. Second and third abdominal tergites without stridulatory pegs ( Fig. 2E ). Eighth abdominal tergite prolonged backwards and ventrad. Ninth abdominal tergite split along the midline, on both sides swollen, ventro-apical angle produced into a short, stout, and incurved spine gradually narrowing to acute tip, apices curved, in situ spines crossing each other ( Fig. 2F ). Subgenital plate broader than long, basal margin nearly straight, posterior margin arched ( Fig. 2F ). Styli cylindrical, upcurved, longer than subgenital plate, inserted at apico-lateral angles of the plate.

Female. Seventh abdominal sternite densely setose. Subgenital plate longer than wide, basal margin straight with 1 pair of copulatory depressions, lateral margins narrowing with middle area contracted ( Fig. 3H, I ), apical half narrowly rounded, posterior margin almost straight. Ovipositor elongate, faintly upcurved, tip subacute ( Fig. 3G ).

Coloration. Body yellowish brown. Frons purple. Eyes, genae and labrum black. Ocelli yellowish. Margins of pronotum black, disc with black patterns as Figs. 2C and 3B . Dorsal spines of hind black.

Measurements (mm). Male: BL 29.6–34.6, PL 7.5–8.7, TL 25.9–41.6, HFL 19.4–21.2; Female: BL 34.5–37.1, PL 8.3–8.8, TL 40.5–40.9, HFL 20.7–22.8, OvL 19.3–22.2.

Material examined. Holotype: male, Fenshuiling , Yunnan, June 16, 2023, coll. by Siyu Pang and Shan Li . Paratypes: 1 male and 2 females, the other information as holotype.

Distribution. Yunnan (Jinping).

Discussion. The new species differs from Capnogryllacris erythrocephala maculatis Liu, Lu & Bian, 2022 in the following: body lighter, yellowish brown, the black pattern of pronotum projecting in middle; male ninth abdominal tergite with short, stout spines, posterior margin of subgenital plate arched instead of obtusely triangularly concave; lateral margins of female subgenital plate contracted in middle, the apical half obvious narrower.

Etymology. Named after the type locality.
