Diagnosis
The external characters of this species are close to those of Biston contectaria, but it can be distinguished from that species by the following differences: the wings are pale yellow but white in Biston contectaria; the forewing postmedial line is much narrower and protruding outwards between CuA2 and 1A + 2A, while in Biston contectaria, it is broader and without such a protrusion; the discal spot on the hindwing upperside is large, round, black, while in Biston contectaria it is almost absent; the discal spots on the underside of both wings are larger and heavier. The male genitalia are close to those of Biston suppressaria, but it can be distinguished by the square apex of the juxta, the shorter median process of the gnathos and the presence of a cornutus which is a short spinous patch. The female genitalia are similar to those of Biston suppressaria. But it differs in that the corpus bursae is coiled anteriorly; the signum is longer and narrower; the ostium bursae is more strongly sclerotized.
