Gelin Village , 29.22338°N, 95.17494°E, 15.VIII.2023, leg. Feng-Qi Guo ( YNAU) . 1♀, China, Xizang Autonomous Region (Tibet), Nyingchi City , Mêdog County, Mêdog Town , nr. Guoguotang Great Ben , Yarang Village , 29°17′56.92″N, 95°16′47.93″E, alt. 725m, 8.VII.2023, leg. Zhi-Sheng Zhang, Lu-Yu Wang, Qian-Le Lu, Xu-Long Chen ( YNAU) .

Coloration. Female ( Fig. 1 A-F, 2A&C, 3A-C). General uniform green, anterior margin of pronotum light yellow; median area of posterior margin on pronotum with a yellow spot. Apex of coxae and femora yellow. Carinae of femora with intermittent black spots. Arolium are all brown. The veins on both forewings and hindwings are dark. The basal part of tegmen with a yellow spot. Costal area of hindwings green but outer with narrow blue margin; in ventral view, costal area of hindwings is blue ( Fig. 3C ). The median area of tergites I-VIII with a big dark spot; the rest area with red coloration but not reach the margins, the margins green or pale yellow.

Nymph ( Fig. 3D ). General coloration yellow. Head with a pair of black spots behind antennae. Compound eyes black. Four angles of pronotum with a big black spot. Four sub-angles of mesonotum black-spotted. Legs generally grey. Coxae yellow. Apex of each femur and tibiae dark. Claws and arolium dark. Abdomen generally light yellow as most of the body. Median area of each tergite with a pair of dark spots; the posterior angles of each tergite with a small black spot.

Hindwing veins. Female ( Fig. 2C ). Costa (C) presents as the foremargin. Subcosta (Sc) spanning ca. 2/3 of the wing length and terminates at the costa. Radius ( R) branches late, ca. 1/3 of the way through the wing into the first radius ( R 1) and radial sector (Rs) which run parallel with each other throughout the wing until the distal 1/10 of the wing where the two veins fused together to the wing apex. Media (M) branches early, divided into media anterior ( MA) and media posterior ( MP) in the position of just start which terminate not touching. Media posterior ( MP) divided into media posterior ( MP) and second media posterior ( MP 2); media posterior ( MP) run through the entire wing to reach the apex of the hindwing; the second media posterior ( MP 2) quicky fused with cubitus (Cu). Cubitus (Cu) runs unbranched and terminates at the wing apex. The first anterior anal (1AA) fuses with the cubitus and then branches from the cubitus. The anterior anal veins two–seven (2AA–7AA) run unbranched. The posterior anal veins (1PA–6PA, 8PA) share a common origin separate from the anterior anal veins and run unbranched to the wing margin with slightly thinner spacing than the anterior anal veins. The seven posterior anal vein (7PA) branch and form 3 cells.

Measurements of female (mm). [Including the data by Bi (1993)] Body: 57.3–65.0; Head: 4.0–4.3; Pronotum: 2.9–3.1; Mesonotum: 6.8–7.0; Profemora: 14.2–15.0; Mesofemora: 11.1–13.0; Metafemora: 15.8–16.5; Protibiae: 13.2–13.7; Mesotibiae: 10.5–10.9; Metatibiae: 14.8–15.3; Tegmen: 4.6–5.0; Hindwing: 50.0–51.1.
