This species ranges from southern Mexico (Veracruz) to western Ecuador and the Cauca Valley of Colombia (Emmons and Feer, 1997). It is found from sea level to 2,600 m in Colombia (Alberico et al., 2000). To the east, this species is replaced by C. lanatus (Eisenberg, 1989), and it apparently does not pass over the eastern cordillera of the Andes. This species is decreasing in number in the northern parts of its range (Mexico and Ecuador).
