The occurrence of Rhogeessa hussoni Genoways and Baker, 1996 in the state of Sergipe is reported here based on an adult female collected in mist nets during a chiropteran survey of the Refúgio da Vida Silvestre Mata do Junco (RVSMata do Junco), a 894 ha fragment of lowland Atlantic Forest. Measurements and taxonomic comments about this species are given. Despite the variability found in coloration of the ventral pelage, qualitative and quantitative characters allowed the identification of the specimen as R. hussoni. The present record increases to twenty-eight the number of bat species recorded for Sergipe and confirms the presence of R. hussoni in the Atlantic Forest biome.
