A new genus of Euptychiina, Emeryus Zacca, Casagrande & Mielke, gen. nov. , is herein described using an integrative taxonomic approach to accommodate three species previously placed in Paryphthimoides Forster, 1964: Emeryus argulus argulus (Godart, [1824]), comb. nov. (type species), Emeryus difficilis (Forster, 1964), comb. nov. and Emeryus numeria (C. Felder & R. Felder, 1867), comb. nov. Additionally, a new taxon Emeryus argulus magnum Zacca , Casagrande & Mielke, ssp. nov. from Venezuela (Aragua and Bolívar) and Brazil (Roraima), is described. A neotype is designated for Satyrus argulus Godart, [1824], and lectotypes are designated for Euptychia huebneri Butler, 1867, Euptychia ambigua Butler, 1867 and Neonympha numeria C. Felder & R. Felder, 1867. Female genitalia are described and illustrated for the first time for all of the above taxa. A Maximum Likelihood analysis using combined nuclear and mitochondrial genes supports the monophyly of the new genus. No DNA sequences could be obtained for E. numeria , but its inclusion in the genus is supported by morphological evidence. The genitalic morphology of both sexes of Emeryus species is helpful in distinguishing this genus from the other Euptychiina, although the male genitalia structures are highly conserved among congeners.
