Diagnosis.

Female. This new species resembles W. truncata Shi, Zhu & Wang, 2022 , but it differs from the latter in: female seventh abdominal sternite weakly sclerotised, posterior margin concave, apices weakly sclerotised and rounded (Fig. 3 D View Figure 3 ).

It is different from W. incurva Shi, Zhu & Wang, 2022 by: female seventh abdominal sternite concolorous with body weakly sclerotised, posterior margin distinctly concave (Fig. 3 D View Figure 3 ). Male. Unknown.

Description

(Based on holotype). No significant variation observed amongst conspecific specimens.

Female. Body large.

Head. Face slightly long, narrow oval; fastigium verticis slightly broader than antennal scape. Eyes ovoid, slightly protruding forward and outward; ocelli relatively distinct, oval and small (Fig. 3 A, B View Figure 3 ).

Thorax. Pronotum broad, anterior margin slightly protruding forward while posterior margin straight (Fig. 3 B, C View Figure 3 ). Lateral areas of second and third abdominal tergites each with 2 rows of stridulatory pegs.

Tegmina and wings. Wings elongate, surpassing apex of stretched hind tibia. Tegmen: R releases Rs near the middle, both forked near apical area; MA releases MP near the third base; CuA releases CuA 1 and CuA 2 near the third base; left tegmen with MP and CuA 1 shortly fuse near the middle while right tegmen not fused; CuP unbranched, free throughout; with 4 anal veins. Hind wing slightly longer than tegmen (Fig. 10 E, F View Figure 10 ).

Legs. Fore coxa with 1 spine at anterior margin. Fore and middle femora unarmed on ventral surfaces; fore and middle tibiae each with 4 pairs of movable long spines and 1 pair of short apical spurs on ventral surfaces, middle tibia with 1 inner apical spur on dorsal surface. Hind femur with 8–10 inner spines and 6–8 outer spines on ventral surface; hind tibia with 6–7 spines on inner and outer margins on dorsal surface, respectively; while apical area with 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Abdomen. Seventh abdominal sternite subquadrate, weakly sclerotised, near apical third widened laterally and elevated forming a pair of lateral lobes, apices rounded; posterior margin concave. Subgenital plate roughly semi-circular, with numerous transverse riffles, apex rounded (Fig. 3 D View Figure 3 ). Cercus long conical, apex slightly acute. Ovipositor relatively short, moderately upcurved, apex rounded (Fig. 3 E View Figure 3 ).

Male. Unknown.

Colouration. Body yellowish-brown. Fastigium verticis and occiput black, antennal socket with the edge black, antenna black; genae under eyes with 1 brown spot separately. Eyes brown. Pronotum with black stripe along entire margin, anterior and posterior margins with black stripes distinctly broadened. Tegmina and hind wings transparent, veins dark brown. Spines and spurs on fore and middle tibiae brown; apices of spines and spurs on hind femur and hind tibia brown.
