Diagnosis.

N. albarius is similar to N. splendens externally, but can be distinguished by the following features: a broad, black band, reaching from costa to anal margin, is present at the base of the forewing, while in N. splendens , it is absent or only present near the anal margin; in the male genitalia, the valvae are longer and narrower, more strongly pointed apically and with a group of strong spines near apex, the terminal part of the juxta is broader and incised, the cornuti are smaller and arranged in a short band. In the female genitalia, the antrum is shorter, the posterior part of the corpus bursae is narrower and more strongly sclerotized, and the signum is larger in N. albarius . By the wing patterns, N. albarius also resembles N. quadratus and N. watanabei in the basal black or greyish brown band, but it is different from N. quadratus by the absence of the quadrate patch near the tornus and the distinct distal spot on the upperside of the forewing, and differs from N. watanabei by the smaller size and the absence of the protrusion on the postmedial band between veins M1 and M3 of the forewing.
