Description. Male. Body stout, brachypterous. Face rugose with numerous distinctly dots ( Fig. 1A View FIGURE 1 ). Fastigium verticis conical in dorsal view ( Fig. 1C View FIGURE 1 ), ventral surface with indistinct median carinula ( Fig. 1B View FIGURE 1 ). Pronotum rugose, anterior margin faintly concave in middle, posterior margin almost straight, median carina indistinct; lateral lobes longer than high, anterior angle broadly rounded, posterior angle rounded, humeral sinus weak ( Fig. 1C, E View FIGURE 1 ). Prosternum smooth; mesosternal lobes with 1 pair of long columnar processes; metasternal lobes with 1 pair of small processes; intermedial plate with 1 pair of small processes at posterior angle ( Fig. 1I View FIGURE 1 ). Fore coxae with 1 small spine; fore femora with 7–9 internal spines on ventral surfaces, tibiae ventrally with 8 internal spines, 6–7 external spines and 1 pair of apical spurs. Middle femora with 7–8 external spines on ventral surfaces; tibiae ventrally with 3 internal and 9–10 external spines, apices with 1 ventral spurs. Hind femora ventrally with 5–8 external spines; tibiae with 10–11 internal spines, 8–9 external spines and 1 pair of apical spurs on dorsal surfaces, ventral surfaces with 3 internal spines, 5 external spines, 1 pair of subapical spurs and 2 pairs of apical spurs. Genicular lobes of hind femora with a small spine on each side ( Fig. 1H–I View FIGURE 1 ). Tegmina reaching the posterior margin of fourth abdominal tergite, apices obtusely rounded and partly overlapped ( Fig. 6A–B View FIGURE 6 ); hind wings shorter than the tegmina. Tenth abdominal tergite projecting backwards, posterior margin arched concave in middle with lateral lobes rounded. Epiproct triangularly rounded with shallow medial furrow on dorsal surface. Paraprocts with 1 pair of short digitate processes. Cerci stout, terminating into apex; the internal margins of apices with 1 small spine which directing inward ( Fig. 2B View FIGURE 2 ), the interno-ventral margins with 1 depressed long spine ( Fig. 2E View FIGURE 2 ), which middle area with 1 dorsal lobe ( Fig. 2D View FIGURE 2 ). Sclerites of titillators with basal areas semisclerotized, arcuately curved, directing laterad ( Fig. 3A View FIGURE 3 ); middle areas prolonged and terminating into apices ( Fig. 3A–B View FIGURE 3 ), which digitate in lateral view ( Fig. 3F View FIGURE 3 ), its apex obtuse and directing forward; apical areas terminating, then slightly expanded, with some denticles at apical margin ( Fig. 3C, F View FIGURE 3 ). Subgenital plate longer than wide, lateral margins moderately convex, curved dorsad and narrowing to apex, ventral surface with 1 pair of lateral carinae, posterior margin straight; styli small, inserted at apico-lateral angles of subgenital plate ( Fig. 2F View FIGURE 2 ).

Female. Pronotum faintly prolonged behind ( Fig. 5A View FIGURE 5 ). Fore femora with 11 internal spines on ventral surfaces, tibiae ventrally with 7–8 internal spines and 6–7 external spines. Middle femora with 7–9 external spines on ventral surfaces; tibiae ventrally with 4 internal and 9 external spines. Hind femora ventrally with 6 external spines; tibiae with 9–10 pairs of dorsal spines, ventral surfaces with 2 internal spines and 4–5 external spines. Tegmina reaching the posterior margin of first abdominal tergite ( Fig. 6C View FIGURE 6 ). Tenth abdominal tergite posteriorly with an obvious concavity in middle ( Fig. 4D View FIGURE 4 ). Epiproct triangular, apex angularly rounded ( Fig. 4D View FIGURE 4 ). Cerci stout and conical, apices acute. Basal area of subgenital plate wider and terminating into apex, the lateral margins obviously constricted in middle, apex with a triangular concavity which narrower and deeper ( Fig. 5D View FIGURE 5 ). Ovipositor as other Chinese Liara species ( Fig. 5B View FIGURE 5 ).

Coloration. Body brown ( Fig. 6 View FIGURE 6 ). Face with green longitudinal band. Eyes, the margins of the antennal cavities, and the basal areas of the first and second antennal segments black ( Fig. 1A View FIGURE 1 ). Clypeal suture black ( Figs. 1A View FIGURE 1 , 4A View FIGURE 4 ). Basal areas of mandibles black. Pronotal disc darker ( Fig. 1C View FIGURE 1 ). Apical areas of all tibiae and basal areas of all femora black. Tegmina with dark cells.

Measurements (mm). Male: BL 38.6, PL 10.1, HFL 15.1, TL 11.5; Female: BL 36.5, PL 8.8, HFL 16.8, TL 7.1, OvL 7.1.

Material examined. Holotype: male, Diding, Jingxi , Guangxi, September 11, 2022, coll. by Qianwen Zhang and Xiangyi Lu . Paratype: 1 female, Diding, Jingxi, Guangxi, September 9, 2022, coll. by Qianwen Zhang and Xiangyi Lu .

Distribution. Guangxi (Jingxi).

Discussion. The new species differs from Liara (Liara) tamdaoensis in: posterior concavity of male tenth abdominal tergite wider ( Fig. 2B View FIGURE 2 ); male cerci with two branches: dorsal branch curved inward, its apices acute ( Fig. 2B View FIGURE 2 ), ventral branch depressed, spine-shaped, apices directing downward, middle area of ventral branch with 1 small lobe ( Fig. 2D View FIGURE 2 ); middle areas of titillators expanded, in lateral view ( Fig. 3A View FIGURE 3 ), apical areas digitiform, then slightly expanded, with some denticles at apex ( Fig. 3F View FIGURE 3 ); posterior margin of male subgenital plate straight ( Fig. 2F View FIGURE 2 ); apical half of female subgenital plate obviously constricted and narrower than Liara (Liara) tamdaoensis (Gorochov, 1994: Fig. 55), the posterior concavity narrower and deeper ( Fig. 5D View FIGURE 5 ).

Etymology. The name of the new species refers to the male cerci with 1 long ventral branch which apex spine-shaped; from Latin long (long) and spin (spine).
