( Figs. 2A–I , 6 )

Type Material. Holotype. ♂, China: Yunnan Province, Fugong County ( ạī县), Shi’Yue’Liang ( eh亮), N 27.2658° E 98.8972°, 1400m, 4.X.2024, Chao Wu leg. ( IZCAS) . Paratypes. 1♂, same data ( IZCAS) .

Description.

Male.

Head. Ovoid, elongate; occiput smooth, dorsally round. Compound eyes large, rounded, anteriorly protruding. Antennae slender, long, flexible, longer than body. Pronotum. Pronotum gradually tilting and widened backwards, with faintly convex anterior margin straight and posterior margins; lateral lobes deeper than long, with straight anterior margin, slightly arched posterior margin, short and slightly curved ventral margin. Legs. Each leg slender, straight. Fore tibia with conchate, significantly swollen inner tympanum, opening of inner tympanum very narrow, slit ( Fig. 2D ); with large and droplet shaped outer tympanum, interior of the outer tympanum completely black ( Fig. 2E ). Hind leg very long. Hind femur enlarged at basal half, and gradually narrowed towards apex, slightly swollen near knee; ventral margin with 8–10 external spines, about 5 spines on apical half clearly larger; the knee with a small black marking, external lobes bispinose, tip of the lobes with sharp spine. Hind tibia longer than the femur; dense small spines are present on the internal and external margins of the tibia dorsal, and small spines on the ventral margins are relatively sparse ( Fig. 2F ). Wings. Tegmina and hind wings fully developed. Leaf-like tegmen opaque, about 6.7 times longer than pronotum, slightly narrow, tapering towards rounded apex; hind wing with apex distinctively projecting beyond tegmen. Stridulatory file on left tegmen stout, droplet shaped, and slightly narrower at anal end ( Fig. 2G ); about 2.5 mm long, with about 40 equally spaced teeth, gradually smaller in size towards both ends ( Fig. 2H ). Hind wing wide, transparent except for tip, colorless, with greenish pale veins. Abdomen. Short, compressed. The tenth abdominal tergite short and thick, the length is less than the width; deeply split into two bulbous lobes in dorsal view, posterior margin broadly rounded, with a wide, circular gap in the middle; significantly curved shape in lateral view, ventral with a small protuberance on apical margin. Cercus hairy, strongly flattened, short; with sharp spine at the tip, strongly curved inward. Subgenital plate elongate, basally broad and slightly narrowing gradually towards the end, deeply divided at the proximal third; apical lobes narrow, roundly emarginated between lobes, with short, conical styli. ( Fig. 2A–C ).

Coloration. Generally yellowish-green when alive, lustrous. Compound eyes bluish green.Antennae yellowish-brown, except for green base. Costal vein on tegmen base light yellow and with very indistinct black anterior edge. Hind wings hyaline, with green exposed part. The tympanum on fore tibia black; all spines on the hind femora and tibia are brown, with black spots at the base of all spines, form dense spots on hind leg; each femora having small black area at the tip, this is particularly evident on the fore and hind femora. Tenth abdominal tergum and subgenital plate yellowish-brown, with a black spot on each side of the base of subgenital plate; cerci yellow, with a black tip. ( Fig. 2I ).

Female. Unknown.

Measurements (length in mm). Body (head to wings end): 59.17–60.23; pronotum: 7.60–7.82; tegmen: 51.25– 52.44; fore femora: 7.76–7.94; hind femora: 31.48–32.20; hind tibiae: 35.77–37.04; stridulatory file: 2.29–2.85.

Etymology. The new species is named after the type locality Fugong County, Yunnan Province.

Discussion. Body large-sized and robust for the genus. The new species is generally similar to Holochlora fruhstorferi Carl, 1914 , H. lancangensis Liu, Zheng & Xi, 1991 and H. qinlangdanga sp. nov.. However, the posterior tibiae of this new species have small black spots at the base of all spines (including dorsal and ventral spines), making them easily distinguishable; the tenth abdominal tergite of males is also different from the latter three species.

Distribution. China, Northwest Yunnan, Nujiang River Basin.
