First record of micronycteris sanborni (chiroptera: Phyllostomidae) from central amazonia, Brazil: Range expansion and description of its echolocation

Abstract

This note reports the first record of Micronycteris sanborni in Amazonas State, Brazil. It extends the species' known range >2000 km northwestward and represents the first record of M. sanborni in a humid tropical ecosystem, suggesting that the species might not be exclusive to dry areas, as previously thought. The individual was captured in Vismia-dominated secondary forest within the fragmented landscape of the Biological Dynamics of Forest Fragments Project. We present morphometric data and provide the first description of the echolocation calls of this poorly known species.
