Remark. Long time the subspecies was erroneously considered by authors as N. effracta (Holloway 2001; Kirti & Singh 2015; Bayarsaikhan & Bae 2016; Bayarsaikhan et al. 2017).

Diagnosis. The subspecies widely varies in its size: the length of forewing is 9.5–11.5 mm in males and 14– 17.5 mm in females. N. sumatrana effractoida ssp. nov . differs from the nominate subspecies in its red forewing pattern, the paler hindwings and the significantly larger signum in the female genitalia. The male genitalia of two subspecies have no significant differences.

Distribution. North and North-East India, Thailand, Laos, Vietnam.

Etymology. The subspecies name refers to the long time confusion of it with N. effracta .
