This paper focuses on the study of inter- and intraspecific variation within the genus Promops in order to evaluate the taxonomic status of some taxa, particularly P. davisoni Thomas, 1921. We analyzed 183 specimens representing all nominal taxa described for the genus, and studied pelage and morphometric characters seeking understanding of the taxonomy of Promops. Based mainly on size allied to pelage characters, we have recognized P. davisoni as a valid species. Relationships of P. davisoni are uncertain, though light brown dorsal pelage in most specimens seems more related to the P. nasutus than P. centralis. Promops davisoni presented cis-Andean allopatric distribution in accordance with range patterns of other bat species.
