A new butterfly species Splendeuptychia ackeryi n. sp., is described from dry habitats in the Magdalena valley of Colombia. It most closely resembles the Ecuadorian east slope endemic S. toynei Willmott & Hall, 1995. Aspects of the morphology, ecology, distribution and conservation of the new species are discussed.
Two new species of Euptychia Hübner, 1818 are described from the upper Amazon basin: Euptychia
attenboroughi Neild, Nakahara, Fratello & Le Crom, sp. n. (type locality: Amazonas, Venezuela), and Euptychia
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.
We describe two new subspecies in two species of Dismorphia Hübner, 1816, from the Sierra Nevada de Santa Marta in Colombia. It also provides a list of about 40 endemics taxa of Pieridae and Nymphalidae supporting taxonomic differentiation (evolutive) and biogeographic center of the Sierra (Nevada) de Santa Marta. We also recorded a Dismorphia amphione bertha as new taxon from from Amazonas, Colombia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
