Figures 1–6
Description. Male. Body stout, brachypterous. Face rugose with numerous distinctly dots (Fig. 1A). Fastigium verticis conical in dorsal view (Fig. 1C), ventral surface with indistinct median carinula (Fig. 1B). 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). 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). 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). Tegmina reaching the posterior margin of fourth abdominal tergite, apices obtusely rounded and partly overlapped (Fig. 6A–B); 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), the interno-ventral margins with 1 depressed long spine (Fig. 2E), which middle area with 1 dorsal lobe (Fig. 2D). Sclerites of titillators with basal areas semisclerotized, arcuately curved, directing laterad (Fig. 3A); middle areas prolonged and terminating into apices (Fig. 3A–B), which digitate in lateral view (Fig. 3F), its apex obtuse and directing forward; apical areas terminating, then slightly expanded, with some denticles at apical margin (Fig. 3C, F). 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).
Female. Pronotum faintly prolonged behind (Fig. 5A). 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). Tenth abdominal tergite posteriorly with an obvious concavity in middle (Fig. 4D). Epiproct triangular, apex angularly rounded (Fig. 4D). 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). Ovipositor as other Chinese Liara species (Fig. 5B).
Coloration. Body brown (Fig. 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). Clypeal suture black (Figs. 1A, 4A). Basal areas of mandibles black. Pronotal disc darker (Fig. 1C). 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); male cerci with two branches: dorsal branch curved inward, its apices acute (Fig. 2B), ventral branch depressed, spine-shaped, apices directing downward, middle area of ventral branch with 1 small lobe (Fig. 2D); middle areas of titillators expanded, in lateral view (Fig. 3A), apical areas digitiform, then slightly expanded, with some denticles at apex (Fig. 3F); posterior margin of male subgenital plate straight (Fig. 2F); 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).
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).
