Paratype. 1♁, same data, 7.IX.2023, Chun-Xiang Liu leg. (IZCAS).
Description. Male.
Head and pronotum. Head ovoid, elongate; fastigium verticis conical, apex obtuse (Fig. 1G); occiput convex, smooth, as wide as pronotum; with length about 1/2 of the pronotum length. Compound eyes large, protruding, ovoid. Antennae slender, much longer than body. Pronotum normal; pronotum gradually tilting and widened backwards; anterior margin concave posterior margin convex, with distinct longitudinal median line (Fig. 1G). Lateral lobes of pronotum longer than deep, angle of smooth dorsal margin and anterior margins of lateral lobe greater than 90º; anterior margins concave, posterior margin convex. Ventral margin of pronotum nearly parallel to dorsal margin, about 2/3 length of pronotum (Fig. 1F).
Legs. Pro- and Mesothoracic legs elongate, very slender (Fig. 1A). Fore femora much longer than pronotum, fore femora with 7 small spines on ventro-internal margin; fore tibiae longer than fore femora, dorsally bearing 4 spines, with about 8 ventral external spines; tympanum swollen and conchate, elongate, opening of the tympanum very narrow, slit, slight swelling at tympana area (Fig. 1H). Middle femora about 3 times longer than pronotum, ventral margin with about 10–12 external spines; middle tibiae as long as femora, dorsally bearing 8–10 internal and 4 external spines, ventral spines about 15. Hind femora very long and slender, 4 times much longer than pronotum, slightly widened in basal half and gradually narrowed towards apex; ventral margin with about 6 external spines. Hind tibiae very slender, longer than femora; dorsally bearing 25–30 similar-sized external and 35–40 internal spines; the external large spines in apical third of hind tibiae interleaved with 1–4 small teeth. All genicular lobes with 2 spines.
Wings. Tegmina very narrow, significantly surpassing apices of abdomen, tapering to rounded apex; cells large, approximately quadrilateral (Fig. 1B). Stridulatory vein strongly bulging on dorsal side of the tegmina (Fig. 1C); stridulatory file approximately straight, moderately curved at basal, stridulatory teeth on underside of left tegmina densely packed, with about 45 teeth (Fig. 1D). Mirror of right tegmina nearly circular, longer than wide (Fig. 1E). Hind wings projecting beyond tegmina, wide, colorless and transparent except at the apex, with pale pink veins.
Abdomen. Short, compressed. Tenth abdominal tergite sclerotized, broad, setose; apical margin producing into two lateral lobes with obtuse apex from middle. Epiproct long, narrowly triangular, with rounded tip. Cerci long, curved, reaching the 2/3 of subgenital plate; terminal inflated, with a stout apical spine. Subgenital plate elongated, without styli; anteriorly wide, narrowing towards middle, apical area split widely into two lateral lobes apex, fishtail, with sharp tip; posterior margin deeply V-sharp excised in middle. (Fig. 2A, B)
External genitalia. Titillator with a pair of short lateral lobes, elongate, narrow, dorsal margin in lateral view strongly curved, with small denticles (Fig. 2B). Phallic lobes ossified, transversal, pigmented on the edges.
Female. Unknown.
Coloration. Body green; head green without black spots, antennae pale brown. Pronotum green with numerous small black spots, including the lateral lobe area. Tegmina green, cells with black spots, stridulatory area yellowish brown, with black marking on the posterior cells. Hindwings hyaline except for green apex; veins pale pink. Legs green, all femur with small black spots, tarsus yellowish-white when alive. Abdomen yellowish green, dorsal side pink, with small dark red rash-like spots; cerci and subgenital plate pale green, cerci with a black tip. (Fig. 3A).
Measurements (mm).
Body length (head to abdomen end): 18.20–19.50; pronotum length: 4.40–4.52; Pronotum height: 2.48–2.55; length of tegmina: 31.24–31.54; width of tegmina: 4.88–4.95; length of hind wing: 33.12–34.93; length of fore femora: 9.80–9.76; length of fore tibiae: 8.61–8.69; length of hind femora: 19.71–19.83; length of hind tibiae: 25.05–25.23.
Etymology. The new species is named after the type locality “Kiukiang” (the old name of Dulong River) and the Latin adjectival suffix “-ensis”, meaning “belonging to”.
