- 13. Liara (Liara) shii Liu & Bian sp. nov. 石氏ffø FIGURES 5–10 Description. Male. Body stout. Fastigium verticis conical in dorsal view (Fig. 5B), ventral surface with indistinct median carinula (Fig. 5A). Face strongly punctured (Fig. 5A). Pronotum rugose, anterior margin almost straight with faintly concave, posterior margin widely arched, transverse sulcus broadly interrupted in middle (Fig. 5B); the lateral lobes longer than high, anterior angle broadly rounded, posterior angle obtusely rounded, humeral sinus faintly exposed (Fig. 5C). Prosternum smooth; mesosternal lobes long and stout; metasternal lobes obtuse; intermedial plate with small obtuse tubercle at posterior angles (Fig. 5D). Genicular lobes spine-shaped, the internal ones obviously longer than the external. Fore coxae with 1 long spine (Fig. 6A); 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), stridulatory file with 125 teeth (Fig. 6C); hind wings shorter than the tegmina. Tenth abdominal tergite prolonged, posterior margin concave in the middle, the lateral lobes obtuse (Figs. 5I, 6D). Cerci stout, terminating to apices, internal margin of basal area with 1 long digitiform process (Fig. 5G); divided in apical area: dorsal branch stout, curved inward, apex acute (Figs. 5H–I, 6D); ventral branch long and sinuate, subapical area slightly expanded on internal margin, apex obtuse with 1 small spine (Figs. 5H–I, 6E–F). 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). Subgenital plate longer than wide, lateral margin curved dorsad, the middle area of the lateral margin slightly convex, posterior margin triangular concave (Fig. 5J); 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, 8A). Tenth abdominal tergite with posterior margin slightly concave in middle (Fig. 8C). Epiproct triangular, apex rounded (Fig. 8C). Cerci conical, apices slightly curved mediad. Subgenital plate longer than wide, posterior margin obtusely rounded concave, apico-lateral angles acutely projecting (Fig. 7F). Ovipositor gradually curved upward with both margins expanding to middle area, then terminating to apices (Fig. 9C–D); apices obtuse (Fig. 8B). Coloration. Brown purple (Fig. 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, 7A), 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). Face with dark green longitudinal band (Figs. 5A, 7A). Dorsal surfaces of head, pronotum and tegmina black brown (Figs. 5B, 7C–D). 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); male subgenital plate triangular concave on posterior margin (Fig. 6J), 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); female subgenital plate and the apico-lateral angles longer than them of the latter species (Fig. 7B). The sclerites of titillators of male phallus of the new species are not expanded in middle area in lateral view (Fig. 6E–F) 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) 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.
