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).
