(IF 0.9) Pub Date : 2017-10-31 Adrià López-Baucells, Ricardo Rocha, Valéria Da Cunha Tavares, Ligiane Martins Moras, Sara Ema Silva, Paulo Estefano Dineli Bobrowiec, Christoph F.J. Meyer
Eumops maurus and Eumops hansae are rarely captured Neotropical molossid bats for which information on taxonomy, natural history, and spatial distribution are scarce. This translates into a poor understanding of their ecology and limits the delimitation of useful characters for their identification. Here, we describe records of these two molossids from the Central Brazilian Amazon, providing data on
