Description. Male. Body stout. Fastigium verticis conical in dorsal view ( Fig. 5B View FIGURE 5 ), ventral surface with indistinct median carinula ( Fig. 5A View FIGURE 5 ). Face strongly punctured ( Fig. 5A View FIGURE 5 ). Pronotum rugose, anterior margin almost straight with faintly concave, posterior margin widely arched, 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 long and stout; metasternal lobes obtuse; intermedial plate with small obtuse tubercle at posterior angles ( Fig. 5D View FIGURE 5 ). Genicular lobes spine-shaped, the internal ones obviously longer than the external. Fore coxae with 1 long spine ( Fig. 6A View FIGURE 6 ); femora with 6–7 internal spines on ventral surface, tibiae ventrally with 7–8 pairs of spines and one pair of apical spines. Middle femora with 7 external spines on ventral surface; tibiae with 4 internal and 10 external ventral spines, apices with 1 pair of ventral spines. Hind femora with 6 external spines on ventral surface; tibiae dorsally with 9–11 internal and 11–12 external spines, ventrally with 3–4 internal and 5–6 external spines, apices ventrally with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Tegmina reaching the middle area of fifth abdominal tergite, apices obtusely rounded and not overlapped ( Fig. 6A View FIGURE 6 ), stridulatory file with 125 teeth ( Fig. 6C View FIGURE 6 ); hind wings shorter than the tegmina. Tenth abdominal tergite prolonged, posterior margin concave in the middle, the lateral lobes obtuse ( Figs. 5I View FIGURE 5 , 6D View FIGURE 6 ). Cerci stout, terminating to apices, internal margin of basal area with 1 long digitiform process ( Fig. 5G View FIGURE 5 ); divided in apical area: dorsal branch stout, curved inward, apex acute ( Figs. 5H–I View FIGURE 5 , 6D View FIGURE 6 ); ventral branch long and sinuate, subapical area slightly expanded on internal margin, apex obtuse with 1 small spine ( Figs. 5H–I View FIGURE 5 , 6E–F View FIGURE 6 ). Sclerites of titillators with apical parts short, curved, denticulate; distal parts of ventral edges with large, subtriangular, sclerotized lateral lobes, which bulging and curved ( Fig. 6E–F View FIGURE 6 ). Subgenital plate longer than wide, lateral margin curved dorsad, the middle area of the lateral margin slightly convex, posterior margin triangular concave ( Fig. 5J View FIGURE 5 ); styli short inserted at the lateral angle of subgenital plate.

Female. Tegmina shorter than male, only reaching the middle area of first abdominal tergite ( Figs. 7D View FIGURE 7 , 8A View FIGURE 8 ). Tenth abdominal tergite with posterior margin slightly concave in middle ( Fig. 8C View FIGURE 8 ). Epiproct triangular, apex rounded ( Fig. 8C View FIGURE 8 ). Cerci conical, apices slightly curved mediad. Subgenital plate longer than wide, posterior margin obtusely rounded concave, apico-lateral angles acutely projecting ( Fig. 7F View FIGURE 7 ). Ovipositor gradually curved upward with both margins expanding to middle area, then terminating to apices ( Fig. 9C–D View FIGURE 9 ); apices obtuse ( Fig. 8B View FIGURE 8 ).

Coloration. Brown purple ( Fig. 9 View FIGURE 9 ), dorsal surface brown to black, ventral surface purple. Eyes, the margins of the antennal cavities, the base of the first and second antennal segments ( Figs. 5A View FIGURE 5 , 7A View FIGURE 7 ), the middle of the clypeal suture, the apices of femora, the dorsal surfaces of the basal third of the fore tibiae, the bases of the middle and hind tibiae black ( Fig. 9 View FIGURE 9 ). Face with dark green longitudinal band ( Figs. 5A View FIGURE 5 , 7A View FIGURE 7 ). Dorsal surfaces of head, pronotum and tegmina black brown ( Figs. 5B View FIGURE 5 , 7C–D View FIGURE 7 ). The venation of the tegmina are yellowish brown (brown membranes are located between the veins).

Measurements (mm). BL: ♂ 26.8–28.1, ♀ 28.6–30.6; PL: ♂ 10.2–10.3, ♀ 8.5–8.8; TL: ♂ 12.8–12.9, ♀ 6.2– 6.8; HFL: ♂ 14.8–15.2, ♀ 16.3–17.4; OvL: 18.3–19.1.

Material examined. Holotype: male, Gulinjing, Maguan , Yunnan, September 20, 2021, coll. by Xiangjin Liu . Paratypes: 3 males and 4 females, other information as holotype. Other specimens: 4 male nymphs and 2 female nymphs, Gulinjing, Maguan , Yunnan, July 27, 2021, coll. by Wei Bin, Xiaoyu Peng & Xun Bian ; 2 male nymphs and 2 female nymphs, Maandi, Jinping , Yunnan, July 30, 2021, coll. by Wei Bin, Xiaoyu Peng & Xun Bian .

Distribution. Yunnan (Jinping, Maguan).

Discussion. The new species differs from Liara (Liara) tamdaoensis in: the ventral branch of male cerci sinuate with apices slightly expanded on internal margin which bispinose in ventral view ( Fig. 6E View FIGURE 6 ); male subgenital plate triangular concave on posterior margin ( Fig. 6J View FIGURE 6 ), while Liara (Liara) tamdaoensis slightly concave posteriorly; the lateral angles of female subgenital plate longer than the latter ( Gorochov, 1994: Fig. 55). And it differs from Liara (Liara) baviensis in: male tenth abdominal tergite posteriorly with middle area concaved ( Fig. 5I View FIGURE 5 ); female subgenital plate and the apico-lateral angles longer than them of the latter species ( Fig. 7B View FIGURE 7 ). The sclerites of titillators of male phallus of the new species are not expanded in middle area in lateral view ( Fig. 6E–F View FIGURE 6 ) as the other two species (Gorochov, 2004: Figs. 71, 75). The new species mainly inhabit the ventral surface of the leaf of Amomum tsaoko (Chinese name: 草果) ( Fig. 10 View FIGURE 10 ) and activate at night.

Etymology. The new species name is dedicated to Professor Fuming Shi (College of Life Sciences, Hebei University) as a recognition to his great contributions to Chinese Ensifera.
