Common Name(s):
English Ecuadorian White-fronted Capuchin, Ecuadorian Capuchin
Spanish Machín Blanco de Occidente, Mono Capuchino
Cebus albifrons ssp. aequatorialis J. A. Allen, 1914
Taxonomic Notes: Molecular genetic analyses by Lynch Alfaro et al. (2010) and Boubli et al. (2012) indicated that Cebus albifrons aequatorialis classified as a subspecies by Hershkovitz (1949), should be considered a distinct species.

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2cd ver 3.1
Year Published: 2015
Date Assessed: 2008-07-01
Assessor(s): Cornejo, F. & de la Torre, S.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B.
This species is listed as Critically Endangered inferred from a serious reduction (>80%) in the forested habitat available over the past 3 generations (48 years). Populations remain in less than 10 protected areas (PN Cerros de Amotape, RN de Tumbes, RE Cotacachi-Cayapas, R. Manglares Churute, R. Mache Chindul, PN Machalilla and small private reserves in the northern western slopes of the Andes) across its range.

Where the species persists it is persecuted as a crop pest by farmers. In other areas they are hunted for bushmeat and for the pet trade.
