A new species of Eumops (Chiroptera: Molossidae) from southeastern Brazil and Bolivia

Abstract Eumops is the most speciose and morphologically diverse genus of Neotropical molossid bats presently encompassing 16 species. Here were described a new species in the genus based on three specimens from southeastern Bolivia and Brazil. A combined phylogenetic analysis using Cytochrome b gene sequences and morphological data revealed that the specimens form a sister-group of Eumops perotis  +  Eumops trumbulli and are 7.9% diverged from E. perotis at Cytochrome b . Three morphological autapomorphies, the shape of rostrum and the position and size of first upper premolar, distinguish new species from E. perotis and E. trumbulli . The combination of morphological and molecular characters justifies the description of a new species.
