Diagnosis.

This species can be distinguished from its congeners by the following characters: the frons is blackish-brown and slightly protruded; the postmedial line of the forewing is almost straight and separating from the medial line under the vein M3. In the male genitalia, the uncus is narrow and T shaped; the socii are long and extending beyond the tip of the uncus; the terminal part of the valvula is weakly sclerotized, its apex is slightly dilated and almost rectangular; the arm between the valvula and the sacculus is as long as the valvula and strongly sclerotized, its apex is dilated, plate-like with irregular serration on the apical margin; both sacculi have a rounded apex, but are asymmetric, as the left side is longer than the right one; the posterior margin of the aedeagus has several small teeth; the cornuti are developed as two sclerotized stripes. The seventh sternite of the female is large, strongly sclerotized, connected with the tergum as a ring, and forms two diverticula on the anterior margin; the colliculum in the female genitalia is stout; the ductus bursae is short and stout.
