Figures 1–4 View FIGURE 1 View FIGURE 2 View FIGURE 3 View FIGURE 4

Description. Male. Body medium, wings absent. Fastigium verticis depressed, projecting forward, dorsal surface with indistinct median furrow ( Fig. 1C View FIGURE 1 ). Ocelli distinct; lateral ocelli located on both sides of fastigium verticis, almost the same size as the median ocellus. Eyes oval, projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices slightly swollen ( Fig. 1A View FIGURE 1 ).

Disc of pronotum smooth, without longitudinal carina, anterior and posterior margins nearly straight; lateral lobes longer than high, ventral margin widely rounded ( Fig. 1F View FIGURE 1 ). Prosternal lobes with basal areas wide and separated from each other, the internal margins constricted behind the base and then terminating into a spine, the external margins straight ( Fig. 1I View FIGURE 1 ); basal half of mesosternum triangular, the lateral margins constricted about middle areas, then terminating into a short spine, its apex obtuse ( Fig. 1H View FIGURE 1 ); metasternum with 1 pair of obtusely triangular processes, basal areas separated, apices obtuse ( Fig. 1G View FIGURE 1 ).

Fore coxae swollen with 1 stout spine; genicular lobes of femora obtuse; tibiae with 1 internal spur on dorsal surface, ventral surface with 4 pairs of spurs, apices with 1 pair of dorsal spurs and 1 pair of ventral spurs; basal areas of tibiae with 1 pair of oval tympana, the internal tympanum ( Fig. 1I View FIGURE 1 ) slightly larger than external one ( Fig. 2A View FIGURE 2 ). Middle coxae also swollen with 1 depressed spine; femora unarmed; dorsal surface of tibiae with 3 internal spurs and 2 external spurs, ventral surface with 4 pairs of spurs, apices with 1 pair of dorsal spurs and 1 pair of ventral spurs. Ventral surface of hind femora with 7 internal spines and 1 external spine, genicular lobes with 1 internal spine, external surface with oblique stripes; dorsal surface of tibiae with 10 pairs of spines and 1 pair of apical spurs (the internal one longer than external one); ventral surface of hind tibiae with 3 internal spurs, 1 external spur and 1 pair of long subapical spurs, apices with 1 pair of long and 1 pairs of short spurs.

First to fourth abdominal tergites with stridulatory pegs ( Fig. 1F View FIGURE 1 ). Posterior margin of ninth abdominal tergite almost straight with 1 dactylitic lobe on each side; posterior margin of tenth abdominal tergite arc concave with 1 pair of sclerotized hooks widely separated which upturned over the lobes of ninth abdominal tergite, its apices directing forward ( Fig. 2E View FIGURE 2 ). Cerci slender. Paraprocl processes about half as long as cerci, lateral margins of basal areas obliquely narrowing and gradually upcurved behind base ( Fig. 2F View FIGURE 2 ); lateral margins arched in dorsal view ( Fig. 2F View FIGURE 2 ); in subapical areas separated from each other, ventral margins faintly widening with converging margins towards subacute tip ( Fig. 2J View FIGURE 2 ). Subgenital plate longer than paraproct processes; basal half swollen with faintly convex and approaching lateral margins ( Fig. 2I View FIGURE 2 ); in apical half with subparallel lateral carinae on ventral surface, the lateral margins rolled-up; posterior margin faintly arched projecting in middle, the lateral angles lobate projecting ( Fig. 2F, J View FIGURE 2 ), with insertion of styli on ventral surface. Styli subcylindrical, behind middle area faintly approaching, apical half faintly compressed with a narrow furrow ( Fig. 2I View FIGURE 2 ).

Female. Body slightly larger than male. Cerci conical, apices acute ( Fig. 4F View FIGURE 4 ). Ovipositor strongly upcurved behind base; basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices of dorsal valvulae subacute ( Fig. 4F View FIGURE 4 ). Subgenital plate wide at base, triangularly narrowing posteriorly and terminating into a short spiniform apical area; basal area nearly twice as long as apical area, lateral margins distinctly constricted at transition between basal and apical areas ( Fig. 4E View FIGURE 4 ).

Coloration. Body black brown, posterior margin of pronotum and the other tergites with short longitudinal pale stripes. Face yellowish-brown, ocelli yellow. Disc of pronotum with yellow median stripe which widened at anterior margin ( Fig. 1D View FIGURE 1 ). All femora yellowish brown with black apices.

Measurements (mm). Male: BL 18.36, PL 6.99, HFL 20.31, HTL 20.83; Female: BL 21.00–22.24, PL7.83– 8.22, HFL 22.52–24.32, HTL 21.03–23.23, OvL 11.64–11.98.

Material examined. Holotype: male, May 28, 2019, Simianshan, Jiangjin, Chongqing, coll. by Sheng Cheng . Paratypes: 1 female, June 2, 2017, Simianshan, Jiangjin, Chongqing, coll. by Huiqin Zhou ; 1 female, May 29, 2019, Simianshan, Jiangjin , Chongqing, coll. by Qionghua Liu. Another specimen : 1 female, June 3, 2021, Simianshan, Jiangjin, Chongqing, coll. by Wenbo Fu .

Distribution. Chongqing (Simianshan).

Discussion. The species differs from Anabropsis (Apteranabropsis) multispinula Lu, Lin, Liu, Liang & Bian, 2022 by: posterior margin of male subgenital plate rectangularly concave, the lateral angles lobate projecting ( Fig. 2I, J View FIGURE 2 .); the apical spine of female subgenital plate about half of basal area ( Fig. 4E View FIGURE 4 ).

Etymology. The name of the new species refers to the female subgenital plate with a short apical spine about half of the triangular base.
