Diagnosis. The species can be distinguished by the following characters: the male hind tibia has four spurs; the postmedial line of the forewing is usually brown, broad and wavy. In the male genitalia, the uncus is long and narrow, slightly dilated and bifid at tip; the valva is very broad and spinose on the ventro-terminal margin; the aedeagus is curved; the cornutus is absent. In the female genitalia, the ovipositor is spinose; the ductus bursae is straight and strongly sclerotized except the anterior part; the signum is large coat-shaped.
