AEüḛâ Figures 1–4 Description. Male/female. Body medium-sized for genus, wings absent. Fastigium verticis depressed, dorsal surface indistinctly furrowed ( Fig. 1B ). Occiput with indistinct median carina. 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 ). Male. Thorax. Disc of pronotum smooth with indistinct longitudinal median carina, anterior and posterior margins substraight; lateral lobes longer than high ( Fig. 1C ). Prosternal lobes with basal areas wide and narrowly separated from each other, lateral margins constricted about the middle area and then terminating into a spine, apices acute ( Fig. 1D ). Mesosternal lobes with basal half convex on both margins; apical half faintly terminated, roughly cylindrical, apices obtuse. Metasternum with 1 pair of obtusely triangular processes, subapical area faintly constricted ( Fig. 1D ). FIGURE 1. Anabropsis ( Apteranabropsis ) brevistria sp. nov .. Male: A. head in frontal view; B–D. head and thorax: B. dorsal view, C. lateral view, D. ventral view; E–F. fore tibia: E. external view, F. internal view; G–H. hind femur: G. external view, H. internal view; I. hind tibia in lateral view. Legs. 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. 1F ) slightly larger than external one ( Fig. 1E ). Middle coxae also swollen with 1 depressed spine; genicular lobes of femora with 1 internal spine; 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 4 internal spines and 5 external spines, genicular lobes with 1 internal spine, external surface with oblique stripes; dorsal surface of tibiae with 10 internal spines, 8 external spines and 1 pair of apical spurs (the internal one longer than external one), ventral surface with 1 internal spur, 2 external spurs and 1 pair of long subapical spurs, apices with 1 pair of long and 1 pair of short spurs.

Male: A–F. apex of abdomen: A. dorsal view, B. dorsal and slightly lateral view, C. slightly apical view, D. lateral and slightly ventral view, E. lateral view, F. ventral view. Abdomen . First to fourth abdominal tergites with small stridulatory pegs ( Fig. 1J ). Posterior margin of ninth abdominal tergite concave with 1 dactylitic lobe on each side; posterior margin of tenth abdominal tergite straight with 1 pair of sclerotized hooks widely separated which upturned over the lobes of ninth abdominal tergite, its apices directing forward ( Fig. 2E ). Cerci slender. Paraproctal processes shorter than cerci, gradually upcurved behind middle area; basal areas triangular in dorsal view ( Fig. 2A ), margins terminating into a spine, in subapical area separated from each other, apices subacute ( Fig. 2D ). Subgenital plate shorter than paraproctal processes, ventral surface with indistinct middle carina; basal half swollen with convex and approaching lateral margins ( Fig. 2F ); in apical half with subparallel lateral carinae on ventral surface; posterior margin faintly concave ( Fig. 2F ), with insertion of styli on apico-lateral angles. Styli subcylindrical. Female. Body slightly larger than that of male. Cerci conical, apices acute ( Fig. 4F ). Ovipositor strongly upcurved behind middle; basal area stout, narrowing to apices; dorsal valvulae longer than ventral ones, ventral margins of subapical area indistinctly widened, apices of dorsal valvulae subacute ( Fig. 4E ). Subgenital plate wide at base, triangularly narrowing posteriorly and terminating into a short spiniform apical area; basal area about as long as apical area ( Fig. 4F ). Coloration. Body blackish brown, pronotal disc with longitudinal yellowish brown stripe along midline which widened at anterior and posterior areas but not reaching the anterior or posterior margins of pronotum. Face yellowish-brown with black spots, ocelli pale yellow. Posterior margins of mesonotum, metanotum and all abdominal tergites with short longitudinal pale stripes. All femora yellowish brown with black apices. Measurements (mm). Male: BL 23.98, PL 8.11, HFL 223.02, HTL 22.81; Female: BL 25.38, PL7.65, HFL 22.70, HTL 21.86, OvL 14.22. Material examined.

Female: A. head in frontal view; B–F. head and pronotum: B. lateral view, C. dorsal view, D. ventral and lateral view, E. ventral view, F. dorsal and slightly apical view; I. hind tibia in lateral view; J. stridulatory pegs in lateral view; G–H. hind femur: G. external view, H. internal view. Distribution. Guangxi (Tianlin). Discussion. This species differs from Anabropsis ( Apteranabropsis ) multispinula Lu, Lin, Liu, Liang & Bian, 2022 by: the longitudinal stripe of pronotum widened at anterior and posterior areas; ventral margins of male paraproctal processes not widened at the subapical areas, apices subacute; the concavity of male subgenital plate roughly V-shaped instead of arched concave; the apical spine of female subgenital plate about as long as basal area ( Fig. 4E ). Etymology. The new species is named for the short longitudinal yellowish-brown stripe on the pronotal disc; from Latin words brev (short) and stri (stripe).
