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.

Etymology. Named after the type locality.
