Autocharis fessalis (Swinhoe, 1886) was described by Swinhoe without a mention of the sex of the type specimen. Autocharis amethystina Swinhoe, [1894] was described by Swinhoe with the type specimen as a male. Hampson, 1896: 415 synonymized amethystina with fessalis depicting the fessalis morphs of Swinhoe, 1886 as females. Hence, according to Hampson, 1896, amethystina is just the female of fessalis. This suggests that this species is sexually dimorphic in wing pattern. However, based on current investigation of both sexes of Autocharis fessalis and Autocharis amethystina shows no sexual dimorphism in wing pattern; hence we believe that the original treatment of treating both these species as valid taxon, holds good, contrary to treatment by Nuss et al 2023 at http://globiz.pyraloidea.org. In the Pyralids of Borneo, too, a mention is made that the two species are probably different, with fessalis being absent in Borneo. Yamanaka (1998) in the Moths of Nepal, Part 5, too treats these two taxa as separate species. See note at http://www.pyralidsofborneo.org/index.php?amethystina. Further investigation by dissections of genitalia of both sexes of both species is needed to conclude this position with certainty (Jahir Rayhan, 10 April 2023).
