Reassessment of the type locality of Godman, 1905, with the description of two new sibling species from Amazonia (Lepidoptera, Nymphalidae, Satyrinae, Satyrini).

A brief historical review regarding the type locality of Godman, 1905 was conducted, which suggests that its type locality is actually Rio de Janeiro, Brazil, rather than northeastern Argentina, as previously purported. Consequently, and its senior synonym Butler, 1871, are regarded to be two species-group names representing a taxon in the euptychiine genus Forster, 1964 known from the Brazilian Atlantic Forest. A lectotype is designated for . Additionally, two closely related species are named and described using an integrative approach with morphological and molecular evidence. Nakahara & Freitas, and Nakahara & Willmott, both occur in Amazonia and COI barcode data recovered these taxa as part of the clade of .
