Description. Male. Body medium, wingless. Fastigium verticis projecting forward, dorsal surface of head without longitudinal carina (Fig. 6B). Lateral ocelli distinct and oval, located on both sides of fastigium verticis; medium ocellus indistinct, located below fastigium verticis, lateral ocelli longer than medium ocellus. Eyes projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices swollen (Fig. 6A).
Disc of pronotum smooth, without longitudinal carina, anterior margin faintly projected, posterior margin arched; lateral lobes longer than high without humeral sinus (Fig. 6C). Prosternum with 1 pair of long spines, apices acute; basal areas of mesosternal lobes widely separated, internal margins obliquely outward, external margins almost straight, apices acute; metasternum with 1 pair of obtusely triangular processes, basal areas separated, internal margins obliquely straight, external margins with basal areas convex and middle areas slightly concave then inclined towards to apices, apices obtuse (Fig. 6D).
Fore and middle coxae swollen, fore coxae with 1 pair of short spines. All femora unarmed on ventral surfaces, genicular lobes of hind femora with 0–1 internal spine, external surface with oblique stripes. Dorsal surface of fore tibiae with 2 internal and 1 external spines, ventral surface with 4 pairs of spurs and 1 pair of apical spurs; basal areas with oval, opened tympana on both sides, the internal one larger than external one (Fig. 6E–F). Dorsal surface of middle tibiae with 4 internal and 3 external spurs, ventral surface with 4 pairs of spurs and 1 pair of apical spurs. Dorsal surface of hind tibiae with 13 internal spines and 13–14 external spines, with 1 pair of apical spurs, the external one longer than internal one; ventral surface with 0–2 internal and 2 external spurs, with 1 pair of subapical spurs, apices with 1 pair of long spurs and 1 pair of short spurs.
First to fourth abdominal tergites with fine stridulatory pegs (Fig. 6G). Posterior margin of ninth abdominal tergite arched. Posterior margin of tenth abdominal tergite concave, lateral margins with 1 pair of hooks, its apices pointing upward. Cerci conical and upcurved (Fig. 6). Paraproctal processes shorter than cerci, upcurved, basal area stout, ventral margins faintly compressed, apices obtuse (Fig. 6I, K–L). Subgenital plate shorter than cerci, basal area wide, narrowing to apices, the width of apical area approximately one third of base, posterior margins slightly concave in the middle. Styli cylindrical (Fig. 6J).
Female. Unknown.
Coloration. Fastigium verticis, antennae, thoracic sternites, abdomen yellow with black spots or stripes. Ocelli and maxillary palpi yellowish (Fig. 6A). Disc of pronotum reddish brown with black spots, lateral lobes dark brown (Fig. 6B). Legs yellow black patches (Fig. 6M).
Measurements (mm). Male: BL 23.6, PL 7.8, HTL 20.7, HFL 20.7.
Material examined. Holotype: male, Gulinjing, Maguan, Yunnan, August 2, 2022, coll. by Xiangyi Liu and Xiaoyu Peng.
Distribution. Yunnan (Maguan).
Discussion. This species is similar to the Anaptosis (Spinanabropsis) sinica Bey Bienko, 1962 in disc of pronotum smooth, without longitudinal carina, all femora unarmed on ventral surfaces; it differs from the latter by the disc of pronotum with a dark red spot at the midline, lateral margins of subgenital plate concave in two-thirds area.
Etymology. The new species’ name comes from the pronotum with a large dark red spot.
