|Scientific Name:||Sapajus flavius Schreber, 1774|
Cebus flavius (Schreber, 1774)
|Taxonomic Source(s):||Lynch Alfaro, J.W., Silva, J.S. and Rylands, A.B. 2012. How different are robust and gracile Capuchin Monkeys? An argument for the use of Sapajus and Cebus. American Journal of Primatology 74(4): 273–286.|
|Taxonomic Notes:||Silva Jr (2001, 2002) argued that the tufted capuchins and the untufted capuchins (sensu Hershkovitz 1949, 1955) are so distinct in their morphology that they should be considered separate genera. Cebus Erxleben, 1777 for the untufted group, and Sapajus Kerr, 1792 is the name available for the tufted capuchins.
Cebus queirozi Pontes and Malta, 2006 in Pontes, Malta and Asfora, 2006, is evidently a junior synonym, or, as argued by Oliveira and Langguth (2006), unavailable for lack of a registered type specimen.
The species was transferred to Sapajus (Lynch Alfaro et al. 2012).
|Red List Category & Criteria:||Critically Endangered C2a(i) ver 3.1|
|Assessor(s):||de Oliveira, M.M., Boubli, J.-P. & Kierulff, M.C.M.|
|Reviewer(s):||Mittermeier, R.A. & Rylands, A.B.|
This species listed as Critically Endangered due to an extremely small population size and continuing decline. The estimated total population is 180 individuals, all of which are extremely fragmented (approximately 24 subpopulations) and averaging approximately 15 individuals.
|Previously published Red List assessments:|
|Range Description:||The coastal region of north-east Brazil in the states of Alagoas, Paraíba and Pernambuco (Oliveira and Langguth 2006; Pontes et al. 2006). Sapajus libidinosus occurs inland (see Oliveira and Langguth 2006).|

|Population:||The remaining populations of this species are all extremely fragmented (approximately 24 subpopulations) each averaging approximately 15 total individuals. The estimated total remaining mature populations size is 180 individuals (M. M. de Oliveira, unpubl.).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Lowland coastal rain forest and Montrichiardia linina swamp in north-east Brazil (Pontes et al. 2006), secondary forest, semi-deciduous seasonal forest, canopy at about 20 m and emergents about 25 m. Capuchin monkeys are arboreal quadripeds, they are typically found in the lower to mid-canopy and understory (Freese and Oppenheimer 1981; Fragaszy et al. 2004; Jack 2007). |
Capuchin monkeys are frugivores-insectivores, including a wide variety of fruits, seeds and arthropods, frogs, nestlings and even small mammals, supplemented by stems, flowers and leaves. They are extractive, manipulative foragers. Typical group size for tufted capuchins is about 18 individuals, with numbers of females exceeding the numbers of males (adult sex ratio of 0.85). Pontes et al. (2006) recorded a group of 18. Males disperse. Both sexes take up linear hierarchies, the top ranking male being dominant to the top ranking female. Subordinate males are often peripheral (Fragaszy et al. 2004).
Adult male HB 36.8 cm, TL 37.8 cm, weight 3.0 kg (Oliveira and Langguth 2006)
Adult male HB 40.0 cm, TL 41 cm, weight 2.9 kg (Pontes et al. 2006)
Adult female HB 35.1 cm, TL 38.4 cm, weight 1.8 kg (Oliveira and Langguth 2006)
Adult female HB 36.1 cm, TL 38.0 cm, weight 2.5 kg (Oliveira and Langguth 2006).
|Major Threat(s):||The major threats are hunting (for food and pets), and habitat loss and fragmentation (mainly through coastal development and sugar cane).|
The species has not been recorded from any protected areas, though several are within range, including Guaribas Biological Reserve (2,714 ha), Barra do Mamanguape EPA (14,640 ha), Manguezais da Foz do rio Mamanguape (Area of Outstanding Ecological Interest; 5,721 ha), and Engenho Gargau RPPN and Mata Estrela RPPN. Surveys over its entire range are needed to establish habitat preferences, area of occupancy, and population numbers.
It is listed on CITES Appendix II.
