Caatinga endemic species. There are records for this species in all portions of the Caatinga. It is distributed in areas from sea level to 983 m elevation. It inhabits all phytophisiognomies of the Caatinga and was recorded recently also in the Atlantic Forest domain near the coast, perhaps as a result of secondary dispersion due to the deforestation of these areas (P. Passos, pers. comm.). It is simpatric with E. crassus in north Minas Gerais, in the Cerrado-Caatinga contact area (Passos & Fernandes 2008). It has semi-arboreal habits, is nocturnal, and feeds on vertebrates (Guedes 2006).
