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. (AU)

ABSTRACT

Bats of the subfamily Desmodontinae are the only hematophagous mammals, represented by three species. Among them, Diaemus youngii has the fewest records in Brazil, being poorly known demographically and ecologically. We report the first record of D. youngii for Mato Grosso state, in central-western Brazil, and provide additional records for the states of Rondônia and Tocantins, in northern Brazil, extending the known distribution of D. youngii in the southern Amazon region.


Os morcegos da subfamília Desmodontinae compreendem as 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.

ABSTRACT

Bat species of the genus Centronycteris are some of the rarest Neotropical Emballonuridae and fewer than 50 specimens have been deposited in scientific collections. The aim of this study is to extend the distribution of Centronycteris maximiliani. Three C. maximiliani specimens were recorded in the Brazilian Amazonia, providing the first record of the species for the state of Rondônia, the southernmost record of the species for the Amazon biome in Brazil, and an additional record for the state of Pará. Although these new records of C. maximiliani reinforce the idea that this species is widely distributed throughout the Amazon biome, its low capture rate reflects the rarity of this species, since only three specimens were collected during three to four year field effort.


Espécies de morcegos do gênero Centronycteris são alguns dos mais raros Emballonuridae Neotropicais e menos de 50 espécimes foram depositados em coleções científicas. O objetivo deste estudo é estender a distribuição de Centronycteris maximiliani. Três espécimes de C. maximiliani foram registrados na Amazônia Brasileira, proporcionando o primeiro registro da espécie para o estado de Rondônia, o registro mais austral da espécie para o bioma Amazônia no Brasil, e um registro adicional para o Estado do Pará. Embora esses novos registros de C. maximiliani reforcem a idéia de que esta espécie é amplamente distribuída por todo o bioma amazônico, a sua baixa taxa de captura reflete a raridade da espécie, uma vez que apenas três espécimes foram coletados durante três a quatro anos de esforço de campo.
