In this article, we present the results of a study about mites associated with bats collected in the State of Pernambuco, northeast Brazil. Of the 331 bats collected, 23 were found naturally infested by mites, corresponding to an overall prevalence of 6.9% (95% confidence interval: 4.5-10.2). Four mite species were collected from seven bat species. The following mite-bat associations were recorded: Periglischrus acutisternus Machado-Allison on Phyllostomus discolor Wagner; Periglischrus ojastii Oudemans on Carollia perspicillata L.; Periglischrus iheringi Oudemans on Artibeus lituratus (Olfers), Artibeus planirostris Spix, Platyrrhinus lineatus (E. Geoffroy), and Sturnira lilium (E. Geoffroy); and Spelaeorhynchus praecursor Neumann on C. perspicillata. This study definitively confirms the presence of S. praecursor in Pernambuco and records for the first time the presence of three spinturnicid species (i.e., P. acutisternus, P. ojastii, and P. iheringi) in northeast Brazil.

<p style="text-align: justify;">Atualmente, quarenta e uma espécies de morcegos são conhecidas para as restingas do Brasil. No entanto, a maioria dos estudos sobre morcegos das restingas são limitados às regiões sul e sudeste do Brasil, deixando a região nordeste com uma lacuna de conhecimento. O presente artigo apresenta dados sobre morcegos capturados em três áreas de restinga do município de Tibau do Sul, Rio Grande do Norte, levantados a partir de uma amostragem de curta duração. Redes de neblina para captura de morcegos foram armadas próximas ao solo e sobre o corpo d’água. Foram capturados 38 indivíduos de seis espécies de duas famílias: cinco Phyllostomidae e um Molossidae. O morcego <em>Carollia perspicillata</em> (Linnaeus, 1758) foi a espécie mais abundante. Apresentamos aqui a primeira lista de morcegos capturados em área de restinga para o Rio Grande do Norte.</p><p style="text-align: justify;"><strong>Palavras chave</strong>: Molossidae, Nordeste, Novo registro, Phyllostomidae, Tibau do Sul.</p><p style="text-align: justify;"><strong>Abstract</strong>: Currently, forty-one species of bats are known to occur in the restingas of Brazil. However, most studies on restingas’ bats are limited to the south and southeastern regions of Brazil, leaving the northeastern region with a gap of knowledge. The present article presents data on bats captured in three areas of restinga of the municipality of Tibau do Sul, Rio Grande do Norte, collected from a short-term sampling. Mist nets were used to capture bats near the ground and the water bodies. Were captured 38 individuals of six species and two families: five Phyllostomidae and one Molossidae. The bat <em>Carollia perspicillata</em> (Linnaeus, 1758) was the most abundant species. We present here the first list of bats captured in the restinga area for the Rio Grande do Norte State.</p><p style="text-align: justify;"><strong>Key words</strong>: Molossidae, New record, Northeast, Phyllostomidae, Tibau do Sul.</p>
