Image: Alouatta discolor

Description: Spix-red-handed-howler (Alouatta discolor) in Alta Floresta, northern Mato Grosso, Brazil. The color of back is reddish-brown, thus, this species is A. discolor, not A. belzebul, since this later has the back entirely black. Also, A. belzebul is enterely black, except the hands, feet and the tail, which is not the case with this specimen. Also this picture was taked in Alta Floresta, Mato Grosso which corresponds to a location within geographic distribution of A. discolor, according Gregorin (2006).
