Diagnosis. Length of forewing is 11.5–12 mm in males and 15.5–16 mm in females. Nephelomilta hortensis fansipana ssp. nov . differs externally from the nominate subspecies in its orange-reddish forewing pattern and paler hindwings. The male genitalia differ from those of N. hortensis hortensis sp. nov. only by the broader medial costal plate, the length of the medial diverticulum of the vesica significantly varies in both subspecies. The female genitalia of N. hortensis fansipana ssp. nov . differ from those of the nominate subspecies in the slightly larger right lateral protrusion of the ductus bursae.

Distribution. The subspecies is known from North Vietnam.

Etymology. The subspecies name refers to its type locality, Fan-si-pan Mountains in North Vietnam.
