Abstract
Herein we present a checklist of the bat species recorded in the municipality of Rio Grande, coastal plain of Rio Grande do Sul state. Thirteen species of three families were recorded through field sampling, collection specimen analysis and bibliography compilation. Molossidae and Vespertilionidae, both with five recorded species, were the most representative families, while three species of Phyllostomidae were recorded. Seven species were found in urban areas. In the sampled natural environments, six species were found in riparian systems, being Myotis albescens and Molossus sp. recorded only in these formations. Riparian systems, hence, can represent relevant habitats for chiropteran conservation in coastal areas of southernmost Brazil.
Highlights
Chiroptera is the second largest mammalian order, with around 1,120 described species (Simmons 2005), which comprises around 22% of all the living mammals (Wilson and Reeder 2005)

Summary
Chiroptera is the second largest mammalian order, with around 1,120 described species (Simmons 2005), which comprises around 22% of all the living mammals (Wilson and Reeder 2005). In Brazil, 172 bat species have been recorded (Reis et al 2011), of which 38 occurring in the southernmost state of Rio Grande do Sul (Pacheco et al 2007). Most of the data concerning bat species records and habitat occupancy in Rio Grande do Sul are restricted to northern and central regions of the state In the southern portion of the geomorphological unit of coastal plain, considered as part of an area of extreme biological importance for mammal conservation in Atlantic Forest and Campos Sulinos biomes (Conservation International do Brasil et al 2000), little effort has been made for the understanding of the richness and ecological features of mammalian fauna assemblages. Aiming to contribute to information gathering about the chiropteran fauna in this region, we present a list of bat species recorded in the municipality of Rio Grande, southern Rio Grande do Sul coastal plain, besides data on habitat occupancy
