Type locality.

Japan (Honshu: Tottori, or Kyoto: Mt. Atago, or Osaka: Mt. Minomo) [A lectotype should be designated, however, the syntypes (from the above mentioned localities) are unavailable presently].

Male.

Forewing length 7.1-7.4 mm, hindwing length 6.2-6.5 mm.

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

Thorax yellow. Legs yellow. Wings transparent, with pterostigmatic areas pale yellow; forewing with brownish stripes on most crossveins except for costal crossveins and with brownish spots on distal branching points of most longitudinal vein; hindwing with brownish spots on distal branching points of Rs, MA and MP; veins mostly yellow, except for those on dark markings brown; costal crossveins on proximal half of forewing costal areas pale brown.

Abdomen yellow, dorsally slightly darker. Gonocoxite 9 robust on proximal half; distal half strongly incurved, ventrally with a short digitiform projection, which bears several spines; gonostylus 9 spinous and forked into a triangular subdistal projection. Ectoproct broad, directed posteroventrad. Complex of gonocoxites + gonostyli + gonapophyses 10 with sinuate lateral arms, which are inflated posterolaterally; distal projections slenderly digitiformed, straightly directed posteriad. Gonocoxites 11 present as a simple, transverse, sclerotized band; gonostyli 11 present as posteriorly bifurcated sclerite.

Female.

Forewing length 7.7-8.9 mm, hindwing length 7.2-7.9 mm.

Fused gonocoxites 8 about 2.0 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, suboval, much longer than tergite 8; proximal portion with a pair of broad sclerotized areas, median portion ventrally with a pair of sclerotized holes, distal portion marginally sclerotized and terminally curved dorsad in lateral view.

Biology and ecology.

Adults have been taken from July–August, most specimens were collected in July. No data concerning the vertical distribution are available. The larva is unknown.

Distribution.
