Diagnosis. Adult: Pronotum pale yellowish-brown, medially with a pair of adjacent longitudinal dark brown stripes, the stripes anteriorly broad; laterally with a pair of short dark lines; lateral margin dark brown; pale yellowish-brown parts narrowed. Mesoscutellum dark brown, medially with a pale yellowish-brown stripe. Forewing rhegma as two short brown spots. Male abdominal tergum 4 mediolaterally with a pair of brown markings, posteriorly with three longitudinal brown stripes; tergum 5 mostly brown, anteriorly pale. The thick part of male external gonocoxites 9 twice as wide as the internal part; gonocoxites 11 slender arched, gonostyli 11 subtriangular in caudal view. Male ectoproct slightly expanded, rounded in lateral view.
Description of adult. Size. Head width: 3.01–3.08 mm; forewing length: 34.28–34.45 mm; hindwing length: 33.88–33.94 mm.
Head. Vertex mostly dark brown, anteriorly with a pair of pale brownish spots ( Fig. 8C View FIGURE 8 ). Scape pale brown; pedicel dark brown; flagellomeres each basally with a dark circular marking, distally pink. Frons with a concave black marking ( Fig. 8B View FIGURE 8 ). Clypeus pale yellowish-brown with a pair of dark dots. Labrum pale brown. Maxillary palpus generally pale yellowish-brown. Labial palpus pale yellowish-brown, distal segment fusiform. Mandibles yellowish-brown with distal half dark reddish brown.
Thorax. Pale yellowish-brown and dark brown. Pronotum pale yellowish-brown, medially with a pair of adjacent longitudinal dark brown stripes, the stripes anteriorly broad; laterally with a pair of short dark lines; lateral margin dark brown; pale yellowish-brown parts narrowed; lateral margin covered with many pale hairs. Mesoprescutum dark brown with a pair of pale yellowish-brown spots; mesonotum medially dark brown, laterally pale yellowish-brown with a pair of longitudinal dark lines, lateral margin dark; mesoscutellum dark brown, medially with a pale yellowish-brown stripe. Metanotum mostly dark brown ( Fig. 8C View FIGURE 8 ). Pleurae generally pale yellowish-brown, with dark brown markings.
Legs. Covered with many pale and dark setae. All coxae pale yellowish-brown each with a distinct dark spot; tibial spurs brown, barely curved; tarsomere 1 generally pale; tarsomeres 2–5 generally dark; tarsomere 5 as long as entire length of tarsomeres 1–4; pretarsal claws slightly curved, protruded basally. Foreleg: Femur pale yellowish-brown, dorsally with two dark brown markings; tibia pale yellowish-brown, medially with a dark brown marking, distally dark brown; tibial spur reaching tip of tarsomere 3. Midleg: Similar to foreleg. Hind leg: Femur pale yellowish-brown, distally dark brown; tibia pale yellowish-brown, basally with a dark brown marking, distally dark brown; tibial spur reaching tip of tarsomere 2; tarsomere 1 longer than that of fore- and midleg ( Fig. 8A View FIGURE 8 ).
Wings. Mostly hyaline, with markings. Forewing longer than hindwing. Pterostigma pale. Forewing costal space with an indistinct dark brown marking proximad pterostigma; rhegma as two short brown spots; cubital area basally with an oblique indistinct dark brown marking; marginal cubital area with scattered dots; costal, distal half of prefork and basal half of posterior crossveins mostly connected by oblique veinlets; four to five presectoral crossveins present, distal presectoral cells biloculate; RP with 10 branches; RP origin basal to MP fork, nearly align at CuA fork. Hindwing mostly hyaline; rhegma as an indistinct brownish spot; two presectoral crossveins present ( Figs. 3A View FIGURE 3 , 8A View FIGURE 8 ).
Abdomen. Male abdomen pale with dark brown markings. Male tergum 1 pale yellow, posteriorly with a black marking; tergum 2 pale yellow, anterolaterally with a pair of oblique dark markings, posteriorly with a dark brown spot; terga 3–4 pale yellow, each mediolaterally with a pair of dark brown markings and posteriorly with three longitudinal brown stripes; tergum 4 medially with a pair of short stout tufts of bristles, the tip of the pair bristles mixed up in a ball of brown wool; tergum 5 swollen, mostly dark brown, anteriorly pale; terga 6–8 each dark brown, anteriorly pale yellow ( Figs. 2B View FIGURE 2 , 18B View FIGURE 18 ). Male genitalia. Sternum 9 subtriangular in ventral view, constricted on distal part, distal part covered with long setae ( Fig. 8E View FIGURE 8 ). Gonocoxites 9 shaped as a pair of plates in caudal view, rounded in lateral view; thick part of male external gonocoxites 9 twice as wide as the internal part; internal gonocoxites 9 as trapezoid. Gonocoxites 11 arched; gonostyli 11 subtriangular in caudal view ( Figs. 8F–J View FIGURE 8 ). Ectoproct slightly expanded, rounded in lateral view, distal margin covered with many curved stout setae ( Figs. 8D–E View FIGURE 8 ). Female genitalia. Unknown.
