Range Description

Alouatta arctoidea is endemic to Venezuela. Its range, following Hill (1962) and Bodini and Pérez-Hernández (1987), is along the Venezuelan coast, east of Lake Maracaibo from Falcón to the state of Miranda. Bodini and Pérez-Hernández (1987) indicated that the howler monkey north of the Río Orinoco and west through Apure basin north of the Rio Meta, widely distributed throughout the Venezuelan llanos, is a distinct, as yet undescribed, form. Linares (1998), however, considered it to be A. arctoidea. Linares (1998) descibed its range as the Cordillera Oriental, Cordillera Central and the Coro System along northern Venezuela, extending south throughout the llanos to the Río Orinoco, between 10 m and 1,160 m above sea level. To date, the species is known only from Colombia, but it may extend into Colombia in Arauca.
