Figures 1–4
Description. Male. Body stout. Face rugose. Fastigium verticis short, conical (Fig. 1C), dorsal surface nearly flat with faintly concave along the midline (Fig. 1C), ventral surface with indistinct median carinula (Fig. 1A). Ocelli distinct, lateral ocelli located on the lateral margins of fastigium verticis.
Thorax. Pronotum rugose, anterior margin widely rounded, posterior margin arched, transverse sulcus broadly interrupted in middle (Fig. 1G); the lateral lobes longer than high, anterior angle widely rounded, posterior angle obtusely rounded, humeral sinus faintly exposed (Fig. 1E). Prosternum smooth; mesosternal lobes nearly triangular, the internal margins straight, the external margins convex, then terminating to the apex, subapical areas constricted, apices obtuse; metasternal lobes roughly triangular, which shorter than mesosternal lobes, the internal margins about half of the external margins, external margins convex, apices short and slightly swollen (Fig. 1F); intermedial plate with a minute lobe at posterior angles on each side (Fig. 1E). Legs. Fore coxae with 1 small spine; femora with 3–4 internal spines on ventral surfaces; tibiae with tympana on both sides, ventrally with 7–9 internal spines and
7 external spines. Middle femora with 4 external spines on ventral surfaces, genicular lobes with 1 internal spine; tibiae ventrally with 2–4 internal and 8–9 external spines. Hind femora ventrally with 6 external spines, genicular lobes with a small spine on each side (Fig. 1H); tibiae dorsally with 13–15 internal spines, 12–13 external spines and 1 pair of apical spurs, ventral surfaces with 3 internal spines, 6–8 external spines, 1 pair of subapical spurs and 2 pairs of apical spurs. Tegmina and wings. Tegmina reaching the posterior margin of fourth abdominal tergite, apices truncate and partly overlapped; hind wings shorter than the tegmina.
Abdomen. Tenth abdominal tergite projecting posteriorly, inverted trapezoidal in dorsal view (Fig. 2A), posterior margin almost straight (Fig. 2C). Epiproct triangularly rounded with shallow medial furrow. Paraprocts faintly swollen. Cerci stout, apical half bifurcated and incurved, the dorsal branch short and wide with ventral surface extended and margins sclerotized (Fig. 2B), the ventral branch slender and long (Fig. 2D). Titillators with basal areas weakly sclerotized, arcuately curved, directing laterad (Fig. 3A); middle areas subrectangular expansion (Fig. 3D); apical areas depressed and straight with denticulate (Fig. 3E). Subgenital plate longer than wide, lateral margins curved dorsally and narrowing to apex, ventral surface with 1 pair of lateral carinae, posterior margin with 1 triangular concavity; styli small, inserted at apico-lateral angles of subgenital plate (Fig. 2F).
Female. Tenth abdominal tergite faintly projecting, posterior margin almost straight with faintly concave median portion (Fig. 4G). Cerci stout and conical, apices subacute. Subgenital plate short with lateral margins obliquely approaching and faintly constricted in middle, posterior margin with a small concavity, the lateral lobes rounded (Fig. 4I). Ovipositor gradually curved upward in subbasal area, ventral margins expanding to middle area, then terminating to apices (Fig. 4J); apices subacute (Fig. 4J).
Coloration. Body yellowish brown. Face reddish with longitudinal green band in middle below fastigium verticis to frontoclypeal suture. Eyes yellowish with black spots. Margins of the antennal sockets, and antennal segments black (Fig. 1A). Basal areas of mandibles black. Pronotal disc darker (Fig. 1C). Apical areas of all spines in legs black. Tegmina with dark cells (Figs. 1G, 4C).
Measurements (mm). Male: BL 31.87, PL 9.58, HFL 16.72, TL 11.97; Female: BL 34.77, PL 9.96, HFL 18.20, TL 8.70, OvL 24.92.
Material examined. Holotype: male, Xiniaogu, Yingjiang, Yunnan, August 23, 2023, coll. by Siyu Pang. Paratype: 1 female, the other information as holotype.
Distribution. Yunnan (Yingjiang).
Discussion. The new species is very similar to Liara (Liara) guangxiensis Bian, Zhang & Li, 2022 in the shape of titillators of male phallus, but differs from the latter by: a) the dorsal br a nch of male cerci hatchet-shaped in apical view (Fig. 1D), the ventral branch more slender (Fig. 2D); b) posterior margin of male subgenital plate with a triangular concavity (Fig. 2F); c) titillators of male phallus with long and wide apical area which denticulate on margins (Fig. 3C); d) female subgenital plate short with a shallow concavity on posterior margin, the lateral lobes rounded (Fig. 4I).
Etymology. Named after the type locality.
