Alera Mabille 1891

Alera Mabille, 1891 is a synonym of Perichares Scudder, 1872

We find (Fig. 13) that Alera furcata Mabille, 1891 and Perichares philetes (Gmelin, [1790]), the type species of both genera (technically, Papilio coridon Fabricius, 1775, a homonym, considered to refer to Perichares philetes, is the type species of Perichares) are genetically close (COI barcodes differ by about 6.5%). Moreover, several species of Alera that we sequenced are not monophyletic and are interspersed between species of Perichares. For these reasons, we consider Alera to be a subjective junior synonym of Perichares.
