Thirteen species of three families were recorded through field sampling, collection specimen analysis and bibliography compilation. Molossidae and Vespertilionidae, both with five Myotisrecorded albescens species, and were Molossus the most sp. representative families, while three species of Phyllostomidae were recorded. Seven species were found in urban areas. inIn coastalthe sampled areas naturalof southernmost environments, Brazil. six species were found in riparian systems, being recorded only in these formations. Riparian systems, hence, can represent relevant habitats for chiropteran conservation Introduction Materials and Methods Chiroptera is the second largest mammalian order, The municipality of Rio Grande (31°47’02” – 32°39’45” S, 52°03’50” – 52°41’50” W) is located in Coastal Plain of which comprises around 22% of all the living mammals Rio Grande do Sul state, southern Brazil (Figure 1).
