Figures 5–6 , 11I

Description. Female. Body medium in size, wings absent. Fastigium verticis projecting forward, slightly narrower than scape, dorsal surface with indistinct longitudinal carina along the midline ( Fig. 5C ). Ocelli distinct, median ocellus oval; lateral ocelli oval, suited on the lateral margins of fastigium verticis. Eyes moderately projecting. Apical segments of maxillary palpi longer than subapical ones, apices slightly swollen ( Fig. 5A ).

Disc of pronotum smooth, without longitudinal carina; lateral lobes longer than deep without humeral sinus, ventral margins arc-shaped ( Fig. 5B ). Prosternal lobes spine-shaped, basal area separated, apices subacute ( Figs. 5D , 6C ); mesosteral lobes with basal area separated, the internal margins almost straight, external margin with basal area widened, the middle area obviously concreted and straight to apices ( Figs. 5D , 6C ); metasternal lobes obtusely angular, basal area separated from each other, internal margin almost straight, external margin slightly convex, apices obtuse ( Figs. 5D , 6C ).

Fore coxae swollen, with 1 strong spine; middle coxae with 1 depressed spinule ( Fig. 5B ). Fore femora unarmed ventrally, genicular lobes obtuse; middle femora ventrally unarmed, genicular lobes with an internal spine; hind femora with 3–6 internal and 1–4 external spines on ventral surface, genicular lobes with an internal spine. Fore tibiae with 1 internal spine and 1 pair of apical spines on dorsal surface, ventral surface with 4 pairs of spines and 1 pair of apical spines, the internal spines longer than external spines; tibial tympana opened on both sides, the internal one larger than external one. Middle tibiae with 3 internal spines, 2 external spines and 1 pair of apical spines on dorsal surface; ventral surface with 4 pairs of spines and 1 pair of apical spines. Hind tibiae dorsally with 9–10 pairs of spines and 1 pair of apical spines; ventral surface with 0–1 internal and 2–4 external spines, subapical area with 1 pair of spines, apical area with 1 long and 1short spines on each side.

Posterior margin of tenth abdominal tergite almost straight. Cerci conical, apices acute, directing dorsad. Subgenital plate longer than wide, basal are triangular, about 1.7 times as long as apical spine ( Figs. 5G , 6E ). Ovipositor short, moderately curved dorsad, basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices subacute ( Fig. 5F ).

Male. Unknown.

Coloration. Body brown with brownish spots ( Fig. 6G–H ). Ocelli pale yellow ( Fig. 5A ). Disc of pronotum black with median yellow band which is slightly widened at anterior and posterior margins ( Fig. 5F ). Apical half of femora and all tibiae black brown, external margin of hind femora with yellowish brown spots. Tergites with short yellowish longitudinal stripes and spots, sternites and ovipositor brown.

Measurements (mm). Female: BL 22.9–29.3, PL 6.7–7.9, HFL 22.2–25.2, HTL 22.2–25.4, OvL 9.3–10.8.

Distribution. Guangxi (Rongshui).

Discussion. The new species differs from Anabropsis (Apteranabropsis) guangxiensis ( Bian & Shi, 2015) in: Body darker, disc of pronotum with yellow longitudinal stripes along the midline which obviously widened at anterior and posterior margins.

Etymology. The new species name refers to the ventral surface of hind femora with more spines.
