Hades Westwood, 1851 is a junior subjective synonym of Methone Doubleday, 1847

Despite their difference in appearance, monotypic genus Methone Doubleday, 1847 (type and the only species Papilio cecilia Cramer, 1777 ) is genetically close to Hades Westwood, 1851 (type species Hades noctula Westwood, 1851 ) (Fig. 15 brown and gray). Therefore, we propose that Hades is a junior subjective synonym of Methone and deduce that the phenotypic difference between Hades and Methone was caused by rapid evolution possibly driven by selection for mimetic appearance of their type species, each in a different mimetic complex.
