PAVE, Romina; GAVAZZA, Alejandra I.; DE SOUZA, Juan  e  GIRAUDO, Alejandro R.. New records of bats (Mammalia: Chiroptera) from Entre Ríos and Santa Fe provinces, Argentina. Rev. Mus. Argent. Cienc. Nat. [online]. 2021, vol.23, n.1, pp.15-25. ISSN 1853-0400.  http://dx.doi.org/10.22179/revmacn.23.717.

The bat fauna of Entre Ríos and Santa Fe Provinces, which are part of the Litoral region in the center and northeast of Argentina, have been scarcely studied. In this study, we analyzed 95 specimens of 15 species of the families Molossidae and Vespertilionidae from field studies and museum collections. We present the first record of Myotis riparius (Vespertilionidae) for Santa Fe Province and the second record of Eptesicus brasiliensis (Vespertilionidae) for Entre Ríos province. We add aspects of ecology, reproduction, and distribution of the studied species, including new locations for different ecoregions of Entre Ríos and Santa Fe. Finally, we present pigmentation disorders, specifically the presence of atypical white spots on the fur for Eumops bonariensis, Eumops patagonicus, and Molossus molossus.

Palavras-chave : Molossidae; Vespertilionidae; Myotis riparius; Eptesicus brasiliensis; Pigmentation; White spots.
