( Figs 25–33 ) Type material. Hඈඅඈඍඒඉൾ: 3, CHINA : T ංൻൾඍ: Shigatze Prefecture, Yadong County,Kambu Maqu (Yadong River), 27°19′47″N , 89°00′06″E , 2250 m , 05.viii.2020 , leg.Yu-Chen Zheng ( DALU ).Pൺඋൺඍඒඉൾ: 1 ♀ , same data as the holotype ( DALU ). Diagnosis. This new species is greatly similar to N. tibetensis Hua & Chou, 1999 and N. xingmini Wang & Hua, 2019 , but can be readily differentiated from them by the immaculate wings ( versus with greatly developed markings), and the shorter (slightly exceeding T4) notal organ on T3 ( vs . longer, exceeding T5). Description. Measurements (mm). Male ( holotype ). AtL 13.8, AbL 14.4, BL 18.6, FL 15.6, FW 3.3, HL 13.3, HW 3.2. Female ( paratype ). AtL 12.5, AbL 7.0, BL 11.1, FL 13.8, FW 2.8, HL 12.5, HW 2.7. Male . Head ( Fig. 25 ). Vertex, ocellar triangle and occiput shining black. Rostrum dark brown with genal area yellowish brown, maxillae and labial palps yellowish brown with dark apices.Antennae black with 42–44 flagellomeres. Thorax ( Fig. 25 ). Pronotum dark brown and lacking stout setae along anterior margin. Meso- and metanotum mostly dark brown with large yellowish brown spot on each side of hind portion. Legs and pleura yellowish brown with apex of tibia and distal tarsomeres blackish. Wings ( Fig. 25 ). Narrow basally with rounded apex. Membrane hyaline and strongly tinged with reddish brown; markings entirely reduced; pterostigma light brown; veins mostly brown with distal cross-veins whitish. Forewing Sc extending to pterostigmal area; R 1 simple; Rs five-branched with R 2 simple; M 4 greatly bent at m-cu; 1A ending far before origin of Rs (ORs); one cross-vein between 1A and 2A. Hindwings similar to forewings with more reduced markings. Abdomen ( Figs 25, 27 ). T1–T5 yellowish brown, S1–S5 light yellowish brown. Notal organ on T3 extending slightly beyond caudal margin of T4, stick-like and greatly raising dorsad in distal 2/3; postnotal organ on T4 rounded. A6 mostly yellowish brown and blackish at lateral base and apical margin, cylindrical.A7 yellowish brown with blackish apical margin, greatly constricted basally and gradually enlarged towards truncated apex; A8 similar to A7 but shorter and beveled at apex. Male genitalia ( Figs 28–31 ). Genital bulb yellowish brown, long oval. Epandrium long, slightly tapering towards truncated apex with strong epandrial lobes. Hypandrium with subtrapezoidal long basal stalk and split into pair of slightly shorter hypovalves. Hypovalves greatly curved, with earlobe-like hypandrial processes at inner base and forming subcircular area basally. Gonocoxites darkened apically; gonostyli slender and slightly longer than half length of gonocoxites, with rounded basal process. Paramere arcuate, simple; stalk broad and slightly fused basally; dorsal bridge short and broad. Ventral valves greatly sclerotized along inner margin and acutely projected basally; dorsal valves short; dorsal processes greatly constricted basally and enlarged distally, waterdrop-like postero-dorsad, slightly exceeding ventral valves in ventral view. Figs 34–35. Type locality of Neopanorpa liuxingyuei sp. nov. and N. zhengyucheni sp. nov. (taken by Yu-Chen Zheng). 34 – Kambu Maqu (Yadong River); 35 – dense vegetation along the river bank. Female . Similar to males in general appearance ( Fig. 26 ). Female genitalia ( Figs 32, 33 ). Subgenital plate long and suboval, with shallow V-shaped emargination apically and long stout setae marginally. Medigynium with axis slightly shorter than half of total length, parallel apodemes densely sclerotized; posterior arms slightly longer than axis, distinctly twisted subbasally and slightly spatulate in apical half. Etymology. This species is named in honor of my friend Mr. Yu-Chen Zheng for collecting the type specimens. Distribution. Indo-Malayan Realm: China : Tibet (Yadong) ( Fig. 1 ). Like in N. liuxingyuei sp. nov. , this species is also highly possible to occur in northwestern Bhutan .
