Eight species of the bat genus Eptesicus are distributed in South America of which four are known fromArgentina. Here, we describe a new species, based on specimens collected from La Rioja Province, and onespecimen from Mendoza Province, Argentina, deposited in a museum collection. This new species of Eptesicuscan be distinguished from other congeners by its golden to yellowish-brown coloration, strong contrast betweendorsal and ventral fur color, long forearm (> 41 mm), and by the relatively short (~ 6 mm) dorsal fur. A detaileddescription of the external and cranial morphology of the new species, as well as comparisons with other speciesof similar size, and present in the same distributional area, are included. A Wilcoxon?Mann?Whitney test and adiscriminant linear function analysis were performed to assess the morphometric differences among species ofEptesicus. The phylogenies obtained by different criteria, as well as those obtained independently from differentgenes, are in agreement with regard to the relationships of the new species.
