Figure 6 View FIGURE 6

Description. Male. Body medium, wingless. Fastigium verticis projecting forward, dorsal surface of head without longitudinal carina ( Fig. 6B View FIGURE 6 ). 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 View FIGURE 6 ).

Disc of pronotum smooth, without longitudinal carina, anterior margin faintly projected, posterior margin arched; lateral lobes longer than high without humeral sinus ( Fig. 6C View FIGURE 6 ). 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 View FIGURE 6 ).

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 View FIGURE 6 ). 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 View FIGURE 6 ). 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 View FIGURE 6 ). Paraproctal processes shorter than cerci, upcurved, basal area stout, ventral margins faintly compressed, apices obtuse ( Fig. 6I, K–L View FIGURE 6 ). 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 View FIGURE 6 ).

Female. Unknown.

Coloration. Fastigium verticis, antennae, thoracic sternites, abdomen yellow with black spots or stripes. Ocelli and maxillary palpi yellowish ( Fig. 6A View FIGURE 6 ). Disc of pronotum reddish brown with black spots, lateral lobes dark brown ( Fig. 6B View FIGURE 6 ). Legs yellow black patches ( Fig. 6M View FIGURE 6 ).

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.
