First record of Peropteryx leucoptera (Chiroptera, Emballonuridae) for the Caatinga of Northeastern Brazil and additional records for the Amazon and Atlantic Rainforest

Peropteryx leucoptera is a widespread species in the Neotropics but with a disjunct distribution in Northern South America and a separated population in the Atlantic Forest of Northeastern Brazil. Here we present new records of this species for Northeastern Brazil, the first records for the Caatinga biome and for the states of Bahia and Rondônia. These new records represent a major range extension and establishes a new southern limit of occurrence for the species. We also examined and provide measurements of other specimens and present an updated map with the distribution of P. leucoptera in South America.
