First record of the genus Promops (Chiroptera, Molossidae) in the state of Rio de Janeiro, Brazil

Bioacoustic data have been expanding knowledge on bat species. The objectives of this work were to describe the first occurrence of Promops at the state of Rio de Janeiro, to provide data on the acoustic parameters found at Ilha Grande, and to provide schedules of the species’ foraging feeding activity. We had a high capture effort with mist nets, but we did not have any capture of P. centralis, for which we obtained acoustics recordings. We increased the number of species recorded for the state of Rio de Janeiro up to 79. This study reassures the importance of using bioacoustic methods alongside mist nets on fieldwork.
