Abstract A new monotypic genus in the ‘ Archeuptychia clade’ Xikrin Barbosa, Freitas, Siewert & Marín gen. nov. (Nymphalidae: Satyrinae: Euptychiina) is described to accommodate a new species, Xikrin ueharapradoi Freitas & Barbosa gen. et sp. nov. , in the highly diverse Satyrinae subtribe Euptychiina, based mainly on molecular data. To date, this species is known only from the region of Carajás, in the eastern Amazon rainforest. The phylogenetic relationship and taxonomy of this new taxon are discussed.
