A new nymphalid species in the subtribe Euptychiina, Euptychia roraima Nakahara, Fratello & Harvey n. sp., is described from Mount Roraima, Guyana. Both internal and external morphology of E. roraima are compared against several Euptychia species and the relationship between E. roraima and congeners is briefly discussed. A strong case is put forth for further and extensive exploration of the Pantepui region concerning its poorly known butterfly fauna. Copyright © 2014 Magnolia Press. Source

Two new species of Euptychia Hübner, 1818 are described from the upper Amazon basin: E. attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (type locality: Amazonas, Venezuela), and E. sophiae Zacca, Nakahara, Dolibaina & Dias, sp. n. (type locality: Acre, Brazil). Their unusual facies prompted molecular and phylogenetic analyses of one of the species resulting in support for their classification in monophyletic Euptychia. Diagnostic characters for the two species are presented based on wing morphology, wing pattern, presence of androconial patches on the hindwing, and genitalia. Our results indicate that the projection of the tegumen above the uncus, previously considered a synapomorphy for Euptychia, is not shared by all species in the genus. The adults and their genitalia are documented, and distribution data and a map are provided. © Andrew F. E. Neild et al. Source
