The genus Dermanura currently comprises 11 species, four of which occur in Brazil. Dermanura anderseni was previously recorded only in the Amazon and Cerrado biomes. Here, we expand the known geographic distribution of D. anderseni over 1000 km eastwards for the Atlantic Forest biome. We captured an adult male specimen in mist-nets set at ground level in the Caju Private Natural Heritage Reserve, Itaporanga D’Ajuda, Sergipe State, northeastern Brazil. Owing to their similarities in external morphology, D. anderseni may be easily mistaken for Dermanura cinerea. Thus, considering that D. cinerea is one of the most common species in the Atlantic Forest of northeastern Brazil, we are alert for the possibility of misidentified specimens in zoological collections.

RESUMOOs morcegos da subfamília Desmodontinae compreendem às únicas três espécies de mamíferos hematófagos. Entre elas, Diaemus youngii é a espécie com menor número de registros no Brasil, sendo pouco conhecida demográfica e ecologicamente. Nós relatamos o primeiro registro de D. youngii para o estado do Mato Grosso, no centro-oeste do Brasil, e fornecemos registros adicionais para os estados de Rondônia e Tocantins, no norte do Brasil. Os registros ampliam a distribuição conhecida de D. youngii no sul da região amazônica.

The Neotropical genusPlatyrrhinusincludes 21 small- to medium-sized bat species. Until recently, the known distribution ofPlatyrrhinus fusciventrisin Brazil was restricted to the Amazon and Cerrado biomes. Herein, we report the easternmost record of this species, extending its distribution to the Caatinga biome, in Northeastern Brazil, Sergipe state. The specimen reported extends the known eastern limit of the species distribution by more than 800 km, suggesting that this species, although preferring rainforest habitats, also possesses the plasticity to exploit resources of the seasonal dry forests, as the Caatinga.

ABSTRACT Lophostoma carrikeri has been mostly recorded within the Amazon biome. There are scarce records in the northern Brazilian Amazon, but also records outside this biome, which were neglected in literature. The aim of this study was to update and extend the distribution of L. carrikeri. Seven new localities in Brazil were provided, including the first records for the states of Rondônia and Mato Grosso, filling a large gap in the species distribution, and three additional records for the state of Pará. Our results reinforce the notion that L. carrikeri is widely distributed in the Amazon, but is also present in other biomes in Brazil, such as Caatinga, Cerrado, and transitional areas.

Abstract:The subfamily Desmodontinae encompasses the only mammals known to feed exclusively on the blood of other vertebrates. This study provides records of the desmodontine bat Diphylla ecaudata from a major gap in its known distribution in northeastern Brazil. Specimens were captured at five localities, all associated with caves. Two of these sites are located in the state of Sergipe, two in Bahia, and one in Ceará. The record of D. ecaudata from Ceará is the first for this state.
