E. sexcinctus is present in a wide area of South America, from southern Suriname and adjacent Brazil to Bolivia, Paraguay, Uruguay, and northern Argentina (Redford and Wetzel 1985). It does not occur in Buenos Aires Province (Flores et al. 2009). For over 20 years, it was thought that a disjunct population existed on the border between Brazil and Suriname (Wetzel 1985). However, recent studies in northern Brazil confirmed the occurrence of E. sexcinctus in Maranhão (Silva Junior et al. 2001), Amapá (Silva Junior and Nunes 2001), and parts of northern (Silva Junior et al. 2005a, b), northwestern (Oliveira et al. 2006), and eastern Pará (Andrade et al. 2006). Most of these records are located in the cerrado. The presence of this species in Peru needs to be confirmed.
