Diagnosis. Adult: Pronotum dark brown, laterally with a pair of wide pale yellowish-brown stripes, a pair of indistinct short dark brown lines present on the pale yellowish-brown stripes. Mesoscutellum pale yellowish-brown, medially with a pair of wide dark brown stripes. Tergum 3 medially with a longitudinal long dark brown stripe, posterolaterally with a pair of short dark brown stripes; tergum 4 posteriorly with three short dark brown stripes; tergum 5 medially with a longitudinal long dark brown stripe, laterally with four pair of dark brown stripes. The strongly sclerotized part of male external gonocoxites 9 thrice as wide as the internal part; gonocoxites 11 widely arched; gonostyli 11 trapezoid in caudal view. Male ectoproct semicircular in lateral view.
Description of adult. Size. Head width: 2.98–3.04 mm; forewing length: 33.32–36.35 mm; hindwing length: 32.53–36.97 mm.
Head. Vertex generally dark brown ( Fig. 12C View FIGURE 12 ). Scape and pedicel each yellowish-brown, internally with a dark brown spot; flagellomeres each basally with a dark circular marking, distally pink. Frons pale yellowish-brown, anterior dark part concave medially, medially with an indistinct transversal dark brown band ( Fig. 12B View FIGURE 12 ). Clypeus pale yellowish-brown, covered with both dark and pale setae. Labrum yellowish-brown. Maxillary palpus generally yellowish-brown, distal segment medially with a dark brown marking. Labial palpus generally yellowish-brown, distal segment fusiform and generally dark brown, distal part yellowish-brown. Mandibles yellowish-brown with distal half dark brown.
Thorax. Dark brown with pale yellowish-brown markings. Pronotum dark brown, laterally with a pair of wide pale yellowish-brown stripes, a pair of indistinct short dark brown lines present on the pale yellowish-brown stripes; lateral margin covered with many pale hairs. Mesoprescutum generally dark brown; mesonotum dark brown and pale yellowish-brown; mesoscutellum pale yellowish-brown, medially with a pair of wide dark brown stripes. Mesonotum generally dark brown ( Fig. 12B View FIGURE 12 ). Pleurae generally dark brown, with pale yellowish-brown markings.
Legs. Covered with many pale and dark setae. All coxae pale yellowish-brown each with a distinct dark spot; femora generally dark brown dorsally and pale yellow ventrally; tibial spurs brown, barely curved; tarsomere 5 as long as entire length of tarsomeres 1–4; pretarsal claws slightly curved, protruded basally. Foreleg: tibia generally dark brown and black, basally and medially with pale yellow markings; tibial spur reaching tip of tarsomere 3; tarsi generally black. Midleg: Similar to foreleg. Hind leg: tibia pale yellow, mediobasally with a dark brown spot, distally dark brown; tibial spur reaching base of tarsomere 3; tarsomeres 1 and 5 pale yellow on basal half, black on distal half; tarsomere 2–4 generally black; tarsomere 1 longer than that of fore- and midleg ( Fig. 12A View FIGURE 12 ).
Wings. Mostly hyaline, with markings. Forewing slightly longer than hindwing. Pterostigma pale. Forewing costal space with a dark brown marking proximad pterostigma; rhegma as a short oblique dark brown stripe and a dark brown dot, sometimes fused as a curved stripe; 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 sometimes biloculate; RP with 9–11 branches; RP origin basal to MP fork, align at CuA fork; posterodistal margin slightly concave. Hindwing mostly hyaline; rhegma as a dark brown spot; two presectoral crossveins present ( Figs. 3C–D View FIGURE 3 , 12A View FIGURE 12 ).
Abdomen. Male abdomen pale with dark brown markings. Male terga 1–2 each dark brown, with a pair of pale yellow markings; tergum 3 medially with a longitudinal long dark brown stripe, posterolaterally with a pair of short dark brown stripes; tergum 4 posteriorly with three short dark brown stripes, 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, medially with a longitudinal long dark brown stripe, laterally with four pair of dark brown stripes; terga 6–8 generally pale yellowish-brown, with brown stripes ( Figs. 2D View FIGURE 2 , 18D View FIGURE 18 ). Male genitalia. Sternum 9 almost rhomboidal in ventral view, distal part covered with long setae ( Fig. 12E View FIGURE 12 ). Gonocoxites 9 shaped as a pair of plates ventral view; thick part of male external gonocoxites 9 thrice as wide as the internal part; internal gonocoxites 9 concave in anteroventral view. Gonocoxites 11 widely arched; gonostyli 11 trapezoid in caudal view ( Figs. 12H–L View FIGURE 12 ). Ectoproct semicircular in lateral view, ventradistal part with stout curved setae ( Figs. 12D–E View FIGURE 12 ). Female genitalia. Pregenital plate tapered. Anterior branches of gonocoxites 8 weakly developed, tuberculate, covered with setae; posterior branches of gonocoxites 8 wide digitiform; gonapophyses 8 as widely bands. Gonocoxites 9 covered with short setae. Ectoproct narrow, distal margin slightly rounded in lateral view ( Figs. 12F–G View FIGURE 12 ).
