Figures 5–6 View FIGURE 5 View FIGURE 6 , 7D–F View FIGURE 7 , 8A–B View FIGURE 8 .

Description. Male. Body stout. Frons punctured. Fastigium verticis conical in dorsal view ( Fig. 5A View FIGURE 5 ), ventral surface with indistinct median carinula ( Fig. 5B View FIGURE 5 ).

Pronotum rugose, anterior margin arched, posterior margin rounded, transverse sulcus broadly interrupted in middle ( Fig. 5B View FIGURE 5 ); the lateral lobes longer than high, anterior angle broadly rounded, posterior angle obtusely rounded, humeral sinus faintly exposed ( Fig. 5C View FIGURE 5 ). Prosternum smooth; mesosternal lobes nearly triangular, the internal margins straight, the external margins convex, then terminating into apex, subapical areas concreted, the apical areas spine-shaped; metasternal lobes with 1 pair of small spines, the external margins obtusely rounded; intermedial plate with a small conical process at posterior angle on each side ( Fig. 5D View FIGURE 5 ).

Fore coxae with 1 small spine; fore femora with 3–5 internal spines on ventral surfaces, tibiae ventrally with 8 internal spines, 6–7 external spines and 1 pair of apical spurs. Middle femora with 5–8 external spines on ventral surfaces; tibiae ventrally with 1–2 internal and 8–9 external spines, apices with 1 ventral spurs. Hind legs absent.

Tegmina reaching the middle area of fifth abdominal tergite, apices obtusely rounded and partly overlapped; hind wings shorter than the tegmina.

Tenth abdominal tergite projecting backwards, posterior margin rounded with arched concave in middle ( Fig. 6B View FIGURE 6 ). Epiproct triangularly rounded with shallow medial furrow. Paraprocts with 1 pair of short compressed processes. Cerci stout, terminating into apex; the internal margins of apices with 1 small spine which directing inward ( Fig. 6B View FIGURE 6 ), the interno-ventral margins with 1 compressed long branch ( Fig. 6D View FIGURE 6 ), which apices with 1 small spine and 1 dorsal lobe ( Fig. 6F View FIGURE 6 ), dichotomous in apical view ( Fig. 6F View FIGURE 6 ). Titillators with basal areas weakly sclerotized, arcuately curved, directing laterad ( Fig. 7D View FIGURE 7 ); middle areas widened ventrally with 1 digitiform process ( Fig. 7F View FIGURE 7 ); apical areas depressed and straight, with subapical areas slightly widened, rounded, denticulate ( Fig. 7D–E View FIGURE 7 ). Subgenital plate longer than wide, lateral margins curved dorsad and narrowing to apex, ventral surface with 1 pair of lateral carinae, posterior margin with 1 shallowly V-shaped concavity; styli small, inserted at apico-lateral angles of subgenital plate ( Fig. 5G View FIGURE 5 ).

Female. Unknown.

Coloration. Body yellowish brown. Face with green longitudinal band ( Fig. 8A, C View FIGURE 8 ). Eyes, the margins of the antennal cavities, and the basal areas of the first and second antennal segments black ( Fig. 5A View FIGURE 5 ). Clypeal suture with 1 circular black spot in middle ( Fig. 5A, E View FIGURE 5 ). Basal areas of mandibles black. Pronotal disc darker ( Fig. 5D View FIGURE 5 ). Basal and apical areas of fore tibiae black ( Fig. 5C View FIGURE 5 ). Tegmina with dark cells. Abdominal sternites reddish purple.

Measurements (mm). Male: BL 28.1, PL 10.2, HFL absent, TL 11.7.

Material examined. Holotype: male, Pinglongshan, Fangchenggang , Guangxi, August 21, 2022, coll. by Qianwen Zhang and Shan Li.

Distribution. Guangxi (Fangchenggang).

Discussion. The new species differs from Liara (Liara) tamdaoensis in the shape of titillators of male phallus.
