Remarks. Coloration and structure of the specimens agree with the description of the species given by Nielson (1982). This species can readily be recognized by the transverse yellow band on the forewing. This species was earlier reported from China, Myanmar, Laos, Thailand, Bangladesh and Vietnam (Nielson, 2015). This is the first report of the occurrence of the species in India.
