Juruá red howler

The Juruá red howler (Alouatta juara) is a species of howler monkey, a New World primate in the family Atelidae, found in Peru and Brazil. It was described by Daniel Giraud Elliot in 1910, and older names for it, Alouatta seniculus juara and Alouatta seniculus amazonica, show that it was once treated as a form of the red howler (Alouatta seniculus) rather than as a species of its own. The Global Biodiversity Information Facility backbone still lists the name as a synonym of that red howler, while the IUCN Red List and several other checklists accept it as a distinct species. Wikipedia files it among the arboreal mammals, animals that live mainly in trees. The IUCN Red List assessed the species in 2021, in an assessment led by J. P. Boubli, and placed it in the Least Concern category. Other English names recorded for it include Juruá red howler monkey and Juruá red howling monkey, and it is called Guariba Vermelha in Portuguese, Aullador Rojo in Spanish and Juruá-Brüllaffe in German.
