Diagnosis.

This new species is very similar to Lista haraldusalis , but the basal area on the forewing is slightly paler than the latter. In the male genitalia, the gnathos has three spines at the apex in the new species while the gnathos has a serrated apex in Lista haraldusalis . Furthermore, the sclerotized plate on the valva strongly extends toward the outer margin in the new species.
