Diagnosis. Adult: Vertex generally dark brown, marginal and medial parts pair yellowish-brown. Pronotum medially generally dark brown, anterolaterally with a pair of curved pale yellowish-brown markings, posterolaterally with a pair of pale yellowish-brown spots. Male terga 3–5 each medially with a longitudinal dark brown marking. The thick part of male external gonocoxites 9 rounded in ventral view, 3.5 times as wide as the internal part; gonostyli 11 narrowed fusiform. Male ectoproct trapezoid in lateral view, rounded on distal margin.
Description of adult. Size. Head width: 2.90–3.01 mm; forewing length: 33.14–35.28 mm; hindwing length: 32.22–34.34 mm.
Head. Vertex generally dark brown, marginal and medial parts yellowish-brown ( Fig. 14C View FIGURE 14 ). 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, lateral margin with a pair of black spots ( Fig. 14B View FIGURE 14 ). Clypeus pale yellowish-brown, covered with dark and pale setae. Labrum yellowish-brown. Maxillary palpus generally yellowish-brown. Labial palpus generally yellowish-brown, distal segment fusiform with a brown marking. Mandibles yellowish-brown with distal half dark brown.
Thorax. Pronotum medially generally dark brown, anterolaterally with a pair of curved pale yellowish-brown markings, posterolaterally with a pair of pale yellowish-brown spot; laterally covered with many pale hairs. Mesoprescutum generally dark brown, lateral margin with a pair of pale yellowish-brown spots and medially with a slender line; mesonotum generally dark brown, medially with a slender rectangular circular stripe; mesoscutellum dark brown, posteriorly pale yellowish-brown. Metanotum generally dark brown ( Fig. 14C View FIGURE 14 ). Pleurae generally dark brown, with some pale yellowish-brown markings.
Legs. Covered with many pale and dark setae. All coxae pale yellowish-brown each with an indistinct dark spot; femora pale yellow on basal half, dark brown on distal half; tibial spurs brown, barely curved; tarsomeres 1–2 generally pale yellow; tarsomeres 3–4 generally dark brown; tarsomeres 5 pale yellow, distally dark brown, as long as entire length of tarsomeres 1–4; pretarsal claws slightly curved, protruded basally. Foreleg: tibia dark brown, basally and medially with pale yellow markings; tibial spur reaching base of tarsomere 3. Midleg: Similar to foreleg. Hind leg: tibia pale yellow, basally with a dark brown spot, distally dark brown; tibial spur reaching base of tarsomere 3; tarsomere 1 longer than that of fore- and midleg ( Fig. 14A View FIGURE 14 ).
Wings. Mostly hyaline, with markings. Forewing longer than hindwing. Pterostigma pale. Forewing costal space with an indistinct brown marking proximad pterostigma; rhegma as a short oblique dark brown stripe and a dark brown dot, sometimes fused as a 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; five to seven presectoral crossveins present, distal presectoral cells sometimes biloculate; RP with 9–10 branches; RP origin basal to MP fork, nearly align at CuA fork; posterodistal margin slightly concave. Hindwing mostly hyaline; rhegma as a dark brown dot; two presectoral crossveins present ( Figs. 2E–F View FIGURE 2 , 14A View FIGURE 14 ).
Abdomen. Male abdomen pale with dark brown markings. Male terga 1–2 generally dark brown; terga 3–5 each medially with a longitudinal dark brown marking; 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; tergum 6 anteriorly pale, other part generally dark brown; terga 7–8 generally dark brown ( Figs. 2E View FIGURE 2 , 18E View FIGURE 18 ). Male genitalia. Sternum 9 subtriangular in ventral view, distal part covered with long setae ( Fig. 14E View FIGURE 14 ). Gonocoxites 9 shaped as a pair of plates ventral view; the thick part of male external gonocoxites 9 rounded in ventral view, 3.5 times as wide as the internal part; external gonocoxites 9 rounded in caudal view; internal gonocoxites 9 appearing as narrowed trapezoid in ventral view. Gonocoxites 11 arched; gonostyli 11 narrowed fusiform in caudal view ( Figs. 14H–L View FIGURE 14 ). Ectoproct trapezoid in lateral view, rounded on distal margin, ventradistal part with stout curved setae ( Figs. 14D–E View FIGURE 14 ). 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 separated bands. Gonocoxites 9 covered with short setae. Ectoproct rounded in lateral view ( Figs. 14F–G View FIGURE 14 ).
