Geoffroy 1806 [265,657,434,461] Mammalia Vespertilionidae Myotis Animalia Chiroptera 25 26 Chordata species ruber   Fig. 41 Taxonomy.  Myotis rubercan be distinguished from their congeners by the general fur coloration, which is bright cinnamon red on the dorsum and yellowish on venter, and higher sagittal and lambdoidal crests.  Myotis simusand  M. ripariuscan present similar coloration, but the attachment of wing membranes on feet and the fur length readily distinguish  M. ruberfrom  M. simus; and the larger forearm length and higher sagittal crests distinguish  M. ruberfrom  M. riparius( Thomas 1902, López-González et al. 2001, Moratelli et al. 2011b). Some specimens of  M. ruberhave reddish nails. Specimens from PECB (ZSP 047, 054; see Table 10for measurements) have bicolored dorsal fur, with blackish brown basis and reddish tips, averaging 6 mmbetween shoulders. The ventral fur is lighter than the dorsal and is bicolored, with dark brown basis and reddish tips. The fringe of hairs on the edge of the uropatagium is absent, the wing membrane is attached to the feet, face is reddish and ears dark brown, and the feet nails are reddish. Distribution. In Brazil, the species is recorded in the Atlantic Forest and Cerrado, on the states of Bahia, Pernambuco, Minas Gerais, Paraná, Rio Grande do Sul, Santa Catarina, São Paulo, Rio de Janeiro, and Espírito Santo( Tavares et al. 2008, Reis et al. 2017). In São Paulo state, there are records on the central and east regions, mostly on the coastal Atlantic Forest ( Garbino 2016). Field observations. We captured two adultmales, both in secondary dense forest. One was taken in a ground-level mist-net set along a river in sampling site M29, and another was taken in a building roof, in sampling site S2 (Appendix 1), where we also captured 17  Molossus molossus, 13  Histiotus velatusand two  Myotis albescens. Captures occurred in May and August.
