Geoffroy, 1805 Fig. 34 Taxonomy. The distinction between M. rufus and M. pretiosus from other Brazilian congeners is discussed above. Molossus rufus is larger than M. pretiosus (forearm ranging from 46.7 to 55.2 mm in M. rufus and from 44.6 to 49.0 mm in M. pretiosus ); the shape of the upper incisors (long and slightly convergent in M. pretiosus , short, spatulated and in contact in M. rufus ); general fur coloration (dark brown in M. pretiosus and dark or reddish brown in M. rufus ) and face and membranes coloration (not black, slightly paler, in M. pretiosus and black in M. rufus ) ( Gregorin and Taddei 2000 , Lim and Engstrom 2001 , López-González and Presley 2001, Gregorin and Taddei 2002 , Eger 2008 , Nogueira et al. 2008 , Gregorin et al. 2011 a , Díaz et al. 2016). Molossus rufus specimens from PECB (ZSP 019, 026, 059; see Table 8 for measurements) have general reddish dark brown coloration, with unicolored dorsal fur, which average 5 mm at the shoulders. The upper incisors are spatulated and in contact. Distribution. In Brazil , the species is recorded in all biomes, except Pampas, on the states of Alagoas , Amazonas, Amapá , Bahia , Ceará , Espírito Santo , Maranhão , Minas Gerais , Mato Grosso do Sul , Mato Grosso , Pará , Paraíba , Pernambuco , Piauí , Paraná , Rio de Janeiro , Roraima , Rio Grande do Sul , Santa Catarina , and São Paulo ( Tavares et al. 2008 , Reis et al. 2017 ). In São Paulo , the species is widely distributed ( Garbino 2016 ). Field observations. We captured 3 adult males in roosting sites on building roofs in sampling sites S7 and S17 (Appendix 1). In S7 we also captured 11 M. molossus and one Cynomops abrasus ; on S17 we also captured one Glossophaga soricina . Captures occurred in January, September and December.
