Diagnosis. The external characters of the species are similar to those of L. mitorrhaphes and L. acutaria, but L. amasa is distinguished by the following characters: the outer margin of the female forms a small protrusion at the end of M3; the dark bands outside the postmedial lines of both wings are reddish brown, while in L. mitorrhaphes and L. acutaria, those are greyish brown; reddish brown scales are present between the forewing submarginal line and the outer margin below M1 and the apex of hind wing, but are absent in L. mitorrhaphes and L. acutaria . The diagnostic characters of the genitalia can be seen under L. mitorrhaphes and L. acutaria .
