Bats (Mammalia: Chiroptera) from two priority areas for biodiversity conservation in the Brazilian Amazon and range extension for Carollia benkeithi (Phyllostomidae)

Abstract

Abstract Amazonian tropical forests host the highest bat diversity in South America. The central area Brazilian Amazon encompasses one of the largest pristine areas within this biome, where Amanã and Mamirauá Sustainable Development Reserves (SDRs) are located. These two reserves hold the status of Priority Areas for Biodiversity Conservation due to their high biological relevance. The aim of this study was to identify the bat species richness within these SDRs to minimize the Wallacean shortfall of the chiropterofauna in the Amazon. A total of 274 specimens, collected 20 years ago and housed in the mammal collection at the Museu Paraense Emílio Goeldi, were sorted and identified. They are distributed across four families, 18 genera, and 26 species: Artibeus planirostris and Carollia perspicillata were the most abundant vouchers. We identified a range extension for Carollia benkeithi and a possible new taxon for the genus Micronycteris.
