Figure 6

Description. Female. Body small. Face ovoid, with scattered impressed dots; fastigium frontis separated from fastigium verticis by a very fine suture (Fig. 6A), fastigium verticis little wider than scape. Ocelli distinct, median ocellus slightly larger than lateral ocelli (Fig. 6A).

Anterior margin of pronotum arched projecting in middle, posterior margin nearly straight (Fig. 6B); lateral lobes longer than high, humeral sinus shallow (Fig. 6C).

Fore coxae with 1 small spine; fore and middle femora unarmed, tibiae ventrally with 4 pairs of spurs and 1 pair of apical spurs. Hind femora with 5 internal and 3 external spines on ventral surface; dorsal surface of tibiae with 6 pairs of spines and 1 pair of apical spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs.

Second and third abdominal tergites with few, very minute stridulatory pegs (Fig. 6D). Seventh abdominal sternite wider than long, the lateral margins convex, ventral surface with 1 swollen, behind it with some transverse riffles (Fig. 6E). Subgenital plate baso-central area largely membranous, lateral margins convex and narrowing, posterior margin with deeply V-shaped concavity, the lateral lobes triangular (Fig. 6E). Ovipositor short, feebly curved; before apices margins strongly narrowing, apices subacute (Fig. 6F).

Male. Unknown.

Coloration. Body yellowish brown. Eyes black. Ovipositor brown.

Measurements (mm). Female: BL 17.29–19.45, PL 3.88–4.45, TL 18.85–19.33, HFL 9.42–9.52, OvL 11.13– 12.34.

Material examined. Holotype: female, Xima, Yingjiang, Yunnan, June 11, 2023, coll. by Weizhong Yang . Paratype: 1 female, Xima, Yingjiang, Yunnan, July 11, 2023, coll. by Weizhong Yang .

Distribution. Yunnan (Yingjiang).

Discussion. The new species differs from other species of the genus in the posterior concavity of female subgenital plate obviously deeper, the lateral lobes triangular (Fig. 6E).

Etymology. The new name refers to the female subgenital plate with deep concavity on posterior margin.
