Male.

Forewing length 8.3-8.9 mm, hindwing length 7.2-7.6 mm.

Head yellow. Antennae yellow. Mouthparts yellow; mandibles with brownish tips.

Prothorax yellow, meso- and metathorax pale brown. Legs yellow. Wings transparent, with pterostigmatic areas pale yellow. Forewing with brown stripes along longitudinal veins posterior to 1st gradate crossveins and branches of CuA, CuP and 1A, and also with brown stripes on most crossveins except for those on pterostigmatic areas. Hindwing only with brownish stripes on 1r-rs and 2r-rs. Veins blackish brown on forewings and pale brown on hindwings, but costal crossveins on pterostigmatic areas and longitudinal veins on proximal half yellow.

Abdomen yellow, dorsally purplish brown. Gonocoxite 9 robust on proximal half, with a small hairy tubercle on inner surface; distal half strongly incurved, ventrally with a subtriangular lobe; gonostylus 9 spinous and unforked. Ectoproct broad, directed posteroventrad, with posterior margin slightly concaved. Complex of gonocoxites + gonostyli + gonapophyses 10 present as a pair of slender straight lobes, which are directed posterodorsally. Gonocoxites 11 present as a simple, transverse, sclerotized band; gonostyli 11 present as posteriorly bifurcated sclerite.

Female.

Forewing length 9.7-9.9 mm, hindwing length 8.3-8.8 mm.

Fused gonocoxites 8 about 1.5 times as long as tergite 8, flatly plate-like. Gonapophyses 8 subtriangular, largely covered by gonocoxite 8, lateral margins distinctly sclerotized. Bursa copulatrix sac-like, subquadrate in ventral view, nearly as long as tergite 8; distal portion internally with an ovoid sclerotized area, terminally curved dorsad in lateral view.
