Remarks: Previously, Psilogramma discistriga (Walker, 1856) was synonymized with Psilogramma menephron by Rothschild and Jordan (1903). It was incorrectly synonymized with Psilogramma melanomera (Butler, 1875) by Eitschberger (2001), but later reinstated as a species by Eitschberger (2010). The species is recorded here for the first time from Manipur.
