Diagnosis
The external characters of this species are close to those of Biston betularia as follows: the male antennae are partially bipectinate and filiform at apex; the forewing postmedial line protrudes outwards between M1 and M3 and between CuA2 and 1A + 2A; the discal spots of both wings are stripe-like. But it can be distinguished from Biston betularia by the following characters: distinctly smaller; the wing colour is dark brown, but greyish black in Biston betularia; the hindwing basal line is present, but absent in Biston betularia; the forewing R1 and R2 are separate, but stalked in Biston betularia. In the male genitalia, the apex of the uncus and the median process of the gnathos are more slender than those of Biston betularia; the valva is more slender and longer; the juxta is much narrower; the cornutus is small and spine-like, whereas Biston betularia has two kinds of cornuti, one is a large bundle of spines, the other is a small tuft of spines. In the female genitalia, the corpus bursae is curved in the anterior half, while in Biston betularia, it is expanded posteriorly and narrow medially; the signum is elliptic, with several small marginal spines, whereas it is bar-like and without marginal spines in Biston betularia.
