Abstract
Mormoopids are a small group of insectivorous bats largely distributed from the southwestern United States throughout Central and South America. They occupy a wide variety of habitats, and in Brazil have usually been associated with habitats in the Amazon, Cerrado, or Caatinga biomes. Nevertheless, most of the information compiled so far to infer their distributional limits is based on roosting colonies occasionally found in caves or on inventories using bat mist netting, which is known to be an ineffective method for capturing aerial insectivorous bats. In this contribution, we present new occurrence records of mormoopid bats based on acoustic surveys in the Caatinga and Cerrado biomes and make an extensive literature review to provide an up-to-date distribution of these bats in Brazil. We additionally describe important parameters of the echolocation calls of mormoopids across the geographical scope of our study, contrasting our data with published information to provide a better overview of the intraspecific acoustic variation of these bat species. Our acoustic data reveal a larger area of occurrence of mormoopids in Brazil than previously known, confirming new records for two states.
