Neurorthus fuscinervis Nakahara, 1915: 16 (odescr, figs: gs female).
Nipponeurorthus fuscinervis : Nakahara 1958 (charact, figs: wing, gs male, female); Hayashi 2005 (list, distr, figs); U. Aspöck and H. Aspöck 2008b (fig: distrmap); Liu et al. 2014 (key, fig: distrmap).
Type locality.
Japan (Kyoto: Mt. Atago).
Male.
Forewing length 8.9-9.3 mm, hindwing length 7.5-7.8 mm.
Head yellow. Antennae yellow. Mouthparts yellow; mandibles with brownish tips.
Thorax yellow. Legs yellow. Wings transparent, immaculate, with pterostigmatic areas yellow; longitudinal veins mostly yellow, except for those posterior to 2nd gradate crossveins brown; crossveins mostly brown, except for those on pterostigmatic areas yellow.
Abdomen yellow, dorsally much darker. Gonocoxite 9 robust on proximal half, with a small hairy tubercle on inner surface; distal half strongly incurved and sinuate, ventrally with two obtuse lobes, one directed outward and bald, the other directed inward and setose; gonostylus 9 acutely pointed but unforked. Ectoproct broad, directed posteroventrad, with posterior margin slightly concave. Complex of gonocoxites + gonostyli + gonapophyses 10 with lateral arms much longer than distal projections, straightly directed; distal projections digitiform, acutely pointed at tip, widely separated and parallelly directed with each other. Gonocoxites 11 present as a simple, transverse, sclerotized band; gonostyli 11 present as posteriorly bifurcated sclerite.
Female.
Forewing length 8.8 mm, hindwing length 7.6 mm.
Fused gonocoxites 8 about 2.0 times as long as tergite 8, flatly plate-like. Gonapophyses 8 subtrapezoidal, largely covered by gonocoxite 8, lateral margins distinctly sclerotized. Bursa copulatrix sac-like, nearly hexagonal in ventral view, slightly longer than tergite 8; distal portion internally with an ovoid sclerotized area, terminally curved dorsad in lateral view.
Specimens examined and records published.

Biology and ecology.
Adults have been taken from July–August. The known vertical distribution is 235-1000 m.
