Hemming (1967) stated:-

Butler introduced the name Cacyreus as a replacement name for Hyreus Hübner, [1819], which is invalid under the Law of Homonymy.

At the time of the publication of Butler's paper the genus Hyreus Hübner was without a type-species; accordingly, Butler was fully entitled to take the course which he did, namely to designate one of the nominal species originally included in Hyreus to be the type-species of his replacement genus Cacyreus, thereby - under Section (i) of Article 67 - designating the same species to be also the type-species of Hyreus Hübner.

The higher classification used here follows Lamas (2008).
