The Maranhão red-handed howler (Alouatta ululata) is an endangered species of howler monkey endemic to forests (for example Babaçu forests) in the northeastern Brazilian states of Ceará, Maranhão and Piauí.[1] It was previously thought to be a subspecies of the red-handed howler, but unlike that species, the Maranhão red-handed howler is strongly sexually dichromatic.[2]
