Maranhao Red-handed Howler

distribution

Alouatta ululata is distributed in the north-east of Brazil, in the north of the states of Maranhão, Piauí, and Ceará (Gregorin 2006) (Fig. 3.1). The typical pelage coloration pattern of this form was first described by Dollman (1910) from individuals collected in Miritiba (Maranhão), but he believed that the specimens that he was analyzing belonged to A. discolor, given that their pelage coloration pattern was similar to the description given by Spix (1823). Later, Elliot (1912) recognized the specimens as part of a distinct species, given that he considered that the type specimen and figure from Spix (1823) portrayed a young A. belzebul individual with the typical darker coloration, and did not accurately match Spix’s description of discolor. Furthermore, Elliot considered that Spix’s description could not be applied to any species of howler known at that time (Elliot 1913). However, Elliot found consistent differences between the specimens from Miritiba and the specimens from the west of Pará, which he considered to be A. belzebul (here A. discolor) and he therefore described it as a distinct species, A. ululata. Ihering (1914), in his review of the genus Alouatta, analyzed a nu
