Description. Male. Body large, wingless. Fastigium verticis projecting forward, about three-fourths as wide as scape, dorsal surface with an indistinct longitudinal carina along the midline ( Figs. 7A , 9A ). Ocelli distinct, median ocellus oval, slightly longer than wide; 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. 7A ).

Disc of pronotum smooth, without longitudinal carina, anterior margin almost straight, posterior margin widely rounded ( Fig. 7B ); lateral lobes longer than deep without humeral sinus. Prosternal lobes spiniform, basal area moderately wide, apices subacute; internal margins of mesosteral lobes straight, subbasal areas of external margins contract narrowing to apices, apices obtuse; metasternal lobes obtusely angular, basal area separated from each other, internal margins almost straight, external margins slightly convex, subapical areas slightly contracted ( Fig. 7D ).

Fore and middle coxae swollen, with 1 depressed spine respectively. Fore and middle femora ventrally unarmed; hind femora on ventral surface; apices of genicular lobes of middle and hind femora with 1 internal spinule, external surface with oblique stripes. Dorsal surface of fore tibiae with 2 internal spines and 1 external spine, ventral surface with 4 pairs of spines; apices with 1 pair of ventral spines; basal area of tibiae with oval, opened tympana on both sides, the internal one larger than external one ( Fig. 7E–F ). Middle tibiae with 4 internal and 3 external apical spines on dorsal surface, ventral surface with 4 pairs of spines and 1 pair of apical spines. Hind tibiae dorsally with 9–10 internal and 9 external spines, apices with 1 pair of spines, the external spine longer than internal one; ventral surface with 1 internal and 2 external spines, apices with 1 subapical spine, 1 long apical spine and 1 short spine on each side.

Posterior margin of ninth abdominal tergite arched concave, lateral margin with 1 pair of subtriangular processes ( Fig. 7J ); posterior margin of tenth abdominal tergite almost straight, lateral areas with a pair of up-curved hooks inserted just laterally of the processes of ninth abdominal tergite ( Fig. 7J ). Paraproctal processes shorter than cerci, upcurved, basal areas stout, narrowing to basal third; dorsal and ventral margins of middle areas nearly parallel ( Fig. 7G ); apices acutely angular, the ventral margin concave and then narrowing to tip, tip acute. Cerci conical, apices obtuse ( Fig. 7I ). Subgenital plate longer than cerci, basal area broad, narrowing to apex, the lateral margins obviously contracted about basal third, ventral surface with 1 pair of parallel longitudinal carinae; posterior margin slightly almost straight ( Figs. 7H , 8C ). Styli cylindrical, inserted the apico-lateral margins. Phallus membranous ( Fig. 7K–L ).

Female. Cerci conical, apices subacute. Subgenital plate longer than wide, basal area triangular, about 1.4 times as long as apical spine ( Fig. 8C ). Ovipositor curved dorsad, basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices of dorsal valvulae narrowly rounded, apices of ventral valvulae acute ( Fig. 8D ).

Coloration. Body brown. Face yellowish brown with blackish spots ( Figs. 7A , 9A, D ). Ocelli pale yellow. Dorsal surface of fastigium verticis, internal margins of antennal sockets, scapes, pedicelli and dorsum of head black, basal segments of flagellar with blackish rings ( Figs. 7B , 8A, C ). Disc of pronotum, mesonotum and metanotum black with yellowish spots at posterior margin ( Fig. 9B, E ); the lateral lobes of pronotum with large brown spot; dorsal surface of abdominal tergites brown with small yellow spots ( Figs. 7C , 8A , 9B, E ). Apical areas of femora and basal areas of tibiae with black spots ( Fig. 11G–H ). Abdominal sternites, basal half of femora and apical half of tibiae and tarsi yellowish brown.

Measurements (mm). Male: BL 28.5–29.5, PL 8.8–9.3, HFL 25.5–29.4, HTL 26.2–29.6; Female: BL 26.9– 33.9, PL 8.1–9.4, HFL 24.3–27.6, HTL 24.2–26.4, OvL 11.2–12.7.

Material examined. Holotype: male (XZ258), Liuwanshan , Guangxi, August 31, 2021, 22.558466° N, 109.856786° E, alt. 904.98 m, coll. by Jing Liu and Xiangyi Lu ; Paratypes: 3 females, the other information as for holotype. Other specimens: 1 male and 1 female, the other information as holotype.

Distribution. Guangxi (Liuwanshan).

Discussion. The new species differs from Anabropsis (Apteranabropsis) guangxiensis ( Bian & Shi, 2015) in: disc of pronotum without yellow longitudinal stripe along the midline ( Fig. 9B, E ), lateral lobes with large brown spot on each side ( Figs. 7B–C , 8A , 9B, E ); basal areas of prosternal lobes obviously widened and almost connected each other ( Figs. 7D , 8B ); the ventral margin of tip of male paraproctal processes forming straight, not hook-shaped in lateral view ( Fig. 7I ); the lateral margins of male subgenital plate contacted about basal third, the areas between the parallel carinae of ventral surface narrower, posterior margin almost straight ( Figs. 7H , 9C ).

Etymology. The new species is named after Professor Fuming Shi who makes great contribution to the Chinese Ensifera.
