﻿AbstractA brief historical review regarding the type locality ofEuptychiastigmaticaGodman, 1905 was conducted, which suggests that its type locality is actually Rio de Janeiro, Brazil, rather than northeastern Argentina, as previously purported. Consequently,E.stigmaticaand its senior synonymE.cyanitesButler, 1871, are regarded to be two species-group names representing a taxon in the euptychiine genusCaeruleuptychiaForster, 1964 known from the Brazilian Atlantic Forest. A lectotype is designated forE.cyanites. Additionally, two closely related species are named and described using an integrative approach with morphological and molecular evidence.CaeruleuptychiaharrisiNakahara & Freitas,sp. nov.andC.aemulatioNakahara & Willmott,sp. nov.both occur in Amazonia andCOIbarcode data recovered these taxa as part of thecaeruleaclade ofCaeruleuptychia.
