Eyes hemispheric, slightly protruding forwards and outwards (Fig. 1A, B). Apical segment of maxillary palpus longer than subapical one, apical area lightly inflated (Fig. 1B). Anterior margin of pronotum straight, posterior margin protruding triangularly (Fig. 1A); lateral lobe longer than high, humeral sinus distinct. Thoracic auditory spiracle exposed completely, peanut-shaped (Fig. 1B). Wings developed, surpassing apices of hind femora, anterior and posterior margins of tegmina nearly parallel, tegmina shorter than hind wings (Fig. 2A, B). All femora without spines on ventral surfaces. Fore coxa with 1 spine, fore tibial tympana open on both sides. Internal and external sides of ventral surface of fore tibiae with 5 spines and 6 spines respectively; middle tibiae with 6 external and 5 internal spines severally on ventral surface; internal and external margins of hind tibiae with 18–20 short spines on dorsal surface separately, as well as 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs respectively. Tenth abdominal tergite with 1 pair of long and depressed posterior processes, curved downwards and apices rounded (Fig. 1C, E, F). Cercus stout in basal half, apical half slender, faintly curved inwards and apex rounded; middle area of inner margin of cercus with a long branch which thin and curved ventrad (Fig. 1C, D, E, F). Subgenital plate broad at base, basal margin acutely concave, with a longitudinal groove in the midline. Styli lightly elongate, apices rounded; inserted on apices of lateral margins of subgenital plate (Fig. 1D). Coloration. Body yellowish green (probably green when alive). Eyes reddish brown. Lateral margins of pronotal disc with a pair of longitudinal and sinuate black stripes. Posterior margin of tegmina dark brown (Fig. 2A, B). All spines and spurs of hind tibiae brown. Female. Appearance is similar to male (Fig. 2A, B). Subgenital plate nearly trapezoidal, posterior margin slightly concave (Fig. 1G). Ovipositor long and straight, apices of ventral valvulae weakly hook-shaped, ones of dorsal valvulae acute (Fig.1H). Material examined.

Body length: ♁11.2–13.1, ♀ 10.9–12.8; pronotum length: ♁3.6–4.1, ♀ 3.6–4.6; hind femur length: ♁11.1–12.8, ♀ 10.1–12.5; tegmen length: ♁22.7–23.8, ♀ 22.3–26.1; ovipositor length: 10.1–12.1. Distribution. China (Yunnan). Remarks. This new species resembles Xizicus (Axizicus) furcus Cui, Liu & Shi, 2020, the differences are: male tenth abdominal tergite with a pair of posterior processes; the inner branch of male cercus longer than the outer one. This new species is also similar to Xizicus (Eoxizicus) uncicercus Mao & Shi, 2015; it differs from the latter in: male cercus observably elongate, inner branch longer than outer one; posterior margin of subgenital plate lightly protruding. Etymology. The name of the new species is named for the type locality.Published as part of Su, Jie, Duan, Yanhao, Liu, Qing & Chang, Yanlin, 2023, One new species of the genus Xizicus Gorochov, 1993 (Orthoptera: Tettigoniidae Meconematinae) from Yunnan, China, pp. 286-290 in Zootaxa 5318 (2) on page 287, DOI: 10.11646/zootaxa.5318.2.9, http://zenodo.org/record/816260
