Distribution. China (Sichuan).

Remarks. This species is endemic to Sichuan Province and is distributed at high elevations (3,000 –3,750 m). Its distribution is wider than that of N. tenuimaculata and N. zheduoshana and overlaps with the latter ( Liao et al. 2021). Some specimens vary slightly in the wing markings: the hindwing has two irregular white spots, sometimes is obvious, even absent ( Hirowatari et al. 2012).
