A revision of the new genus Nakahara, Willmott & Espeland, gen. n., described for Fabricius, 1776 (Lepidoptera, Nymphalidae, Satyrinae).

We here propose a new, monotypic genus, Nakahara, Willmott & Espeland, , to harbor a common Neotropical butterfly, described as Fabricius, 1776, and hitherto placed in the genus Forster, 1964. Recent and ongoing molecular phylogenetic research has shown to be polyphyletic, with proving to be unrelated to remaining species and not readily placed in any other described genus. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil. A neotype is designated for the names and its junior synonym, Cramer, 1780, resulting in the treatment of the latter name as a junior objective synonym of the former. A lectotype is designated for Bates, 1865, which is treated as a subspecies, (Bates, 1865), , based on molecular and morphological evidence. We also describe two new taxa, Nakahara & Espeland, and Nakahara & Marín, , new subspecies from the western Andes and eastern Central America, and northern Venezuela, respectively.
