Hemming (1967) stated:-

The taxon represented by the nominal species Papilio angelica Stoll is currently treated subjectively on taxonomic grounds as being the same as that represented by the older-established nominal species Papilio c-aureum Linnaeus, 1758 (Syst. Nat. (ed. 10) 1 : 477.

It must be noted at this point that the nominal species Papilio c-aureum Linnaeus is the type-species of the genus Polygonia Hübner, [1819]. The names Eugonia Hübner and Polygonia Hübner are thus subjective synonyms of one another, and, as they were published on the same date and in the same work - these names actually appearing on the same page - the relative precedence to be accorded to them depends on the choice of the First Reviser. Up to the year 1934 Grote's type-selection of Papilio angelica in 1873 for the genus Eugonia was completely overlooked and the genus was treated as having a quite different species, Papilio polychloros Linnaeus, as its type-species, authors following in this matter the invalid selection of that species made by Scudder in 1875 (Proc. amer. Acad. Arts Sci., Boston 10 : 170). These two species had never been treated as being congeneric with one another by any author who accepted either the genus Eugonia or the genus Polygonia. In consequence, no First Reviser choice was made as between these names ; nor was there any cause for such a choice until in 1934 (Gen. Names hol. Butts 1 : 71) I drew attention to the fact that in consequence of Grote's selection of Papilio angelica Stoll as the type-species of Eugonia Hübner it had become necessary to determine the relative precedence to be accorded to the names Eugonia and Polygonia. I thereupon acted on the so-called principle of page and line precedence and accordingly adopted the name Polygonia Hübner, sinking the name Eugonia Hübner as a synonym of Polygonia. The correct course would have been simply to make an express First Reviser choice as between these names, but as the action then taken complies in all respects with that required of a First Reviser, it ranks as such under the Code. The position is therefore that the name Eugonia Hübner ranks as a junior subjective synonym of Polygonia for all who regard the respective type-species of those genera to be congeneric with one another.

The higher classification used here follows Lamas (2008).
