Six species of Eptesicus Rafinesque, 1820 occur in Brazil : E. andinus J.A. Allen, 1914 , E. brasiliensis (Desmarest, 1819) , E. chiriquinus Thomas, 1920 , E. diminutus Osgood, 1915 , E. furinalis (d’Orbigny and Gervais, 1847) and E. taddeii Miranda, Bernardi & Passos, 2006 ( Nogueira et al. 2014 ). E. andinus and E. chiriquinus can be distinguished from congeners by the length of dorsal fur (> 8 mm in E. andinus , and E. chiriquinus , < 8 mm in the other species; Simmons and Voss 1998 , Miranda et al. 2006 , Davis and Gardner 2008 ). Eptesicus taddeii can be distinguished from E. diminutus and E. furinalis by size (forearm 44.1–48.7 mm in E. taddeii , and < 42.5 mm for E. diminutus and E. furinalis – Mies et al. 1996 , Simmons and Voss 1998 , Miranda et al. 2006 ). The distinction between E. taddeii and E. brasiliensis is based on the shape of the ears (rounded in E. taddeii and more triangular in E. brasiliensis ), muzzle shape (more inflated in E. taddeii than in E. brasiliensis ) and size, E. taddeii being larger than E. brasiliensis (forearm 44.1–48.7 mm versus 40.5–46.5 mm ; Miranda et al. 2006 ). Specimens from PECB (ZSP 017, 048; see Table 10 for measurements) were identified as E. taddeii because of the following characters: short dorsal fur (ca. 6 mm ), triangular ears with rounded terminal portion, muzzle inflated, and forearm length within the variation reported. According to Miranda et al. (2006) , the dorsal fur in E. taddeii is bicolored, with the basal two-thirds brown and tips red. This pattern was observed on the specimens from PECB, which have bicolored dorsal fur, with a large mid brown basal band and reddish tips. The ventral fur is also bicolored, with a large mid brown basal band and contrasting reddish tips, pattern similar to the described by Miranda et al. (2006) . Distribution. In Brazil , the species is only known from the Atlantic Forest, on the states of São Paulo , Paraná , Santa Catarina , and Rio Grande do Sul ( Tavares et al. 2008 , Reis et al. 2017 ). In São Paulo there are records in only three localities in the central and east portions of the state ( Garbino 2016 ). Field observations. Two adult females were taken on mist-nets set at ground-level in sampling sites M20 and M34, and one was taken on a mist-net elevated 8 m over a trail, in sampling site M7 (Appendix 1). Captures occurred in March, June and November. A pregnant female was captured in March.
