Nipponeurorthus Nakahara: Hayashi 2005 (list, distr, figs); U. Aspöck and H. Aspöck 2007 (fig: distrmap); U. Aspöck and H. Aspöck 2010a (fig: distrmap); Liu et al. 2014 (overview, fig: distrmap).
Diagnosis.
Adults of small body-size; male forewing length 6-10 mm. Body coloration generally yellow. Forewings transparent to pale yellowish brown, sometimes with brown markings, sometimes with spectacular colour pattern. Costal crossveins of forewings at least partially forked in most species. Hindwing MA and anterior branch of MP forked distal to outer series of gradate crossveins in most species. Male abdominal segment 7 sometimes enlarged. A ring-like zone of glands sometimes present between male abdominal segments 8 and 9. Abdominal eversible sacks - as e.g. in Nevrorthus - are so far found only in Nipponeurorthus fasciatus (between segments 8 and 9). Male sternite 9 short, not strongly extending posteriad; gonocoxites 9 present as a pair of robust claspers, terminally with gonostyli 9; complex of gonocoxites + gonostyli + gonapophyses 10 present as a pair of discrete sclerites with long blade-like, spinous, or claw-like distal lobes, free or more or less attached (or amalgamated respectively) with sternite 9, as lateral “frame” and terminal sclerites (appearing as a pseudoapex of sternite 9); gonocoxites 11 reduced to sclerite claspers which might represent the gonostyli 11, located between bases of gonocoxites 9. Fused female gonocoxites 8 broad, nearly twice as long as tergite 8; gonocoxites 9 foliate or club-shaped; bursa copulatrix comprising a sclerotized structure.
