Description. Male. Body large.
Head. Fastigium verticis projecting forward, slightly narrower than the scape, dorsal surface with indistinct longitudinal carina along the midline ( Fig. 5B View FIGURE 5 ). Ocelli distinct, median ocellus roughly circular; lateral ocelli oval, suited on the lateral margins of fastigium verticis. Eyes projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices slightly swollen ( Fig. 5D View FIGURE 5 ).
Thorax. Disc of pronotum smooth, without longitudinal carina, anterior margin almost straight, posterior margin arched ( Fig. 5B View FIGURE 5 ); lateral lobes longer than deep without humeral sinus, ventral margins arc-shaped ( Fig. 5D View FIGURE 5 ). Prosternal lobes spine-shaped, basal area separated, apices acute; mesosteral lobes with the basal area convex on both margins and separated, then terminating into a spine, its apex obtuse; metasternal lobes obtusely angular, basal area separated from each other, external margin obliquely straight, internal margin slightly convex and constricted on subapical area, apex obtuse ( Fig. 5C View FIGURE 5 ).
Legs. Fore coxae with 1 stout spine; genicular lobes of femora obtuse; tibiae with 2 internal spurs and 1 external spur on dorsal surface, ventral surface with 4 pairs of spurs and 1 pair of apical spurs; basal areas of tibiae with 1 pair of oval tympana, the internal tympanum ( Fig. 5F View FIGURE 5 ) slightly larger than external one ( Fig. 5G View FIGURE 5 ). Middle coxae with 1 depressed spine; femora unarmed; dorsal surface of tibiae with 4 internal spurs and 3 external spurs, ventral surface with 4 pairs of spurs and 1 pair of apical spurs. Ventral surface of hind femora with 11–13 internal spines and 1–3 external spines, genicular lobes with 1 internal spine; dorsal surface of tibiae with 10 pairs of spines and 1 pair of apical spurs (the internal one longer than external one), ventral surface with 2 internal spurs, 1 external spur and 1 pair of long subapical spurs, apices ventrally with 1 pair of long and 1 pair of short spurs.
Wings. Wings small, laterad, and justly reaching the posterior margin of metanotum or anterior margin of first abdominal tergite ( Fig. 5E View FIGURE 5 ). Hind wings covered by tegmina.
Abdomen. First to fourth abdominal tergites with stridulatory pegs ( Fig. 5I View FIGURE 5 ). Posterior margin of ninth abdominal tergite arched concave, lateral margins with 1 lobe on each side ( Fig. 6A View FIGURE 6 ); posterior margin of tenth abdominal tergite almost straight, lateral areas with a pair of upcurved hooks inserted just laterally of the processes of ninth tergite ( Fig. 6C View FIGURE 6 ). Paraprocts triangular with a pair of long and upcurved processes ( Fig. 6D View FIGURE 6 ), apical margins concave with a long oblique-triangular projection on dorso-apical margin that carry at nearly subacute tip, ventro-apical angle rounded ( Fig. 6D View FIGURE 6 ). Cerci conical, about as long as paraprocts, apices obtuse ( Fig. 6D View FIGURE 6 ). Subgenital plate shorter than cerci, basal half swollen with convex and approaching lateral margins ( Fig. 6E View FIGURE 6 ); apical half with 1 pair of subparallel lateral carinae on ventral surface; posterior margin with a triangular concavity ( Fig. 6E View FIGURE 6 ). Styli cylindrical, as long as the wide between them, inserted at the apical angles of subgenital plate on posterior margin ( Fig. 6E View FIGURE 6 ).
Female. Body large. Wings reaching the posterior margin of metanotum. Cerci conical, apices acute. Subgenital plate transverse at base, triangular narrowing posteriorly and terminating into a long spine-shaped apical area; basal area about half as long as apical area, lateral margins distinctly constricted at transition between basal and apical areas ( Fig. 8E View FIGURE 8 ). Ovipositor gradually upcurved behind middle, basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices of dorsal valvulae obtuse ( Fig. 8D View FIGURE 8 ).
Coloration. Body brown with yellowish spots. Face yellowish brown with black spots ( Figs. 5A View FIGURE 5 , 7A View FIGURE 7 ). Ocelli pale yellow. Internal margins of antennal scokets, scapes, and pedicelli black, flagellar segments with a brownish ring on each segment. Tegmina black brown ( Figs. 5E View FIGURE 5 , 7E View FIGURE 7 ). Disc of pronotum with irregularly yellowish brown spots; posterior margin of pronotum, mesonotum, metanotum and dorsal surfaces of abdominal tergites with short, yellowish stripes. Abdominal sternites yellowish brown. Apical areas of femora and basal areas of tibiae black.

Distribution. Guangxi (Darongshan, Shiwandashan).
Discussion. The species differs from Anabropsis (Pseudapteranabropsis) tonkinensis Rehn, 1906 by: male paraproctal processes with bifurcate apical area in lateral view ( Fig. 6F View FIGURE 6 ), posterior margin of male subgenital plate triangularly concave ( Fig. 5E View FIGURE 5 ), apical spine of female subgenital plate about two times as long as basal area ( Fig. 8E View FIGURE 8 ).
Etymology. The name refers to the bifurcated apical area of male paraproctal processes.
