First record of Macrophyllum macrophyllum (Schinz, 1821) in Brazilian mangroves, with comments on bat diversity in this ecosystem

We present the first record of Macrophyllum macrophyllum for a mangrove ecosystem, a review of the records of this bat in Rio de Janeiro state, and a checklist of bats from Brazilian mangroves. Captured at APA Guapimirim, this specimen represents the fifth record for Rio de Janeiro state, raising the number of species known from Brazilian mangroves to 39, most of them being insectivores. The new record may reflect both the difficulty of sampling this species using traditional methods, and the lack of mammalian research in mangroves. Such studies, however, would be important for the conservation of an ecosystem that is constantly under human disturbance.
