Diagnosis. Adult: Vertex generally dark brown. Frons generally dark brown. Pronotum dark brown, medially with a longitudinal slender yellowish-brown line, laterally with a pair of discontinuous yellowish-brown stripes and a pair of continuous yellowish-brown stripes. Mesoprescutum generally dark brown. Forewing rhegma as an oblique dark brown stripe. Male tergum 3 generally brown with dark brown markings; tergum 4 without rows of dense pores, posteriorly with three short dark brown stripes; tergum 5 posteriorly dark brown. Male gonocoxites 9 semicircular in caudal view; short tapered setae on internal gonocoxites 9 arranged in a narrowed triangular; ectoproct 1.5 times as wide as the maximum width of sternum 9. Female posterior branches of gonocoxites 8 wide, curved at right angle. Description of adult. Size. Head width: 2.92–3.08 mm; forewing length: 30.22–33.54 mm; hindwing length: 26.02–29.67 mm.

Head. Vertex generally dark brown ( Fig. 21C View FIGURE 21 ). Scape and pedicel each pale yellowish-brown, basally dark brown; flagellomeres each generally dark brown, distally yellowish-brown. Frons generally dark brown ( Fig. 21B View FIGURE 21 ). Clypeus pale yellowish-brown, with a pair of dark brown spots, covered with both dark and pale setae. Labrum yellowish-brown. Maxillary palpus yellowish-brown on first segment, medial and distal segments dark brown. Labial palpus generally yellowish-brown, distal segment fusiform and dark brown. Mandibles yellowish-brown with distal half dark brown.

Thorax. Pronotum dark brown, medially with a longitudinal slender yellowish-brown line, laterally with a pair of discontinuous yellowish-brown stripes and a pair of continuous yellowish-brown stripes; laterally covered with both dark and pale hairs. Mesoprescutum generally dark brown; mesonotum generally dark brown, laterally with indistinct yellowish-brown markings; mesoscutellum generally dark brown, laterally with irregular indistinct yellowish-brown markings. Metanotum generally dark brown, posteriorly with a pair of yellowish-brown spots; metascutellum dark brown ( Fig. 21B View FIGURE 21 ). Pleurae generally dark brown.

Legs. Covered with many pale and dark setae. All coxae pale yellowish-brown each basally dark brown; tibiae yellowish-brown, with two dark brown spots, distally dark brown; tibial spurs yellowish-brown, barely curved; pretarsal claws slightly curved, protruded basally. Foreleg: Femur basally and distally yellowish-brown, medially dark brown; tibial spur reaching tip of tarsomere 3. Mid leg: Similar to foreleg. Hind leg: Femur yellowish-brown, distally and ventrally dark brown; tibial spur reaching tip of tarsomere 2; tarsomere 1 longer than that of fore- and midleg ( Fig. 21A View FIGURE 21 ).

Wings. Infuscate, narrow, long ovoid, with scattered markings. Male wings darker than that of female ( Figs. 19 C–D View FIGURE 19 ). Hindwing 0.85 times as long as forewing. Pterostigma pale. Forewing costal space with a dark brown marking proximad pterostigma; rhegma as an oblique dark brown stripe; cubital area basally with an oblique indistinct dark brown marking; costal, distal half of prefork and basal half of posterior crossveins mostly connected by oblique veinlets; five presectoral crossveins present, distal presectoral cells sometimes biloculate; RP with eight to nine branches; RP origin basal to MP fork, nearly align at CuA fork. Hindwing rhegma as an indistinct dark brown spot; one presectoral crossvein present on male, two presectoral crossveins present on female ( Figs. 19 C–D View FIGURE 19 ).

Abdomen. Male abdomen pale with dark brown markings. Male terga 1–2 generally dark brown; tergum 3 generally brown with dark brown markings; tergum 4 without rows of dense pores, posteriorly with three short dark brown stripes; tergum 5 pale, posteriorly dark brown, barely swollen (squeezed on holotype); tergum 6 pale, with indistinct dark brown marking; terga 7–8 generally dark brown ( Figs. 2I View FIGURE 2 , 22C View FIGURE 22 ). Male genitalia. Sternum 9 subtriangular, distally with long setae; tergum 9 laterally with long setae ( Figs. 21D–E View FIGURE 21 ). Gonocoxites 9 semicircular in caudal view, anteriorly with short setae in ventral view; short tapered setae on internal gonocoxites 9 arranged in a narrowed triangular. Gonocoxites 11 thick, longer than gonocoxites 9 in lateral view; gonostyli 11 protruded dorsally ( Figs. 21H–K View FIGURE 21 ). Ectoproct dark brown, medially with a yellowish-brown spot, laterally expanded into digital projection, 1.5 times as wide as the maximum width of sternum 9; distal margin with many stout long setae ( Figs. 21D–E View FIGURE 21 ). Female genitalia. Pregenital plate tapered. Anterior branches of gonocoxites 8 weakly developed, tuberculate, covered with setae; posterior branches of gonocoxites 8 digitiform, wide, curved at right angle. Gonocoxites 9 covered with short, stout setae. Ectoproct narrowed semicircular ( Figs. 21F–G View FIGURE 21 ).

Type material. Holotype ♂, CHINA: Yunnan, Diqing, Weixi County [ĠZ县], Zhonglu Township [中ƃ乡], Zanli Village [咱利ť], 1695 m, 5.VII.2022, Zhihao Qi ( IZCAS) . Paratypes: 1♀, same information as holotype ( IZCAS) .
