|Scientific classification |
Although there are differences between individuals as well as between the sexes and across age groups, S. xanthosternos is described as having a distinctive yellow to golden red chest, belly and upper arms. Its face is a light brown and its cap for which the capuchins were first named is a dark brown/black or light brown. Formerly thought to be a subspecies of tufted capuchin (S. apella), it was elevated to the status of species. Despite this previous classification, S. xanthosternos does not have very evident tufts, as they are oriented towards the rear of the skull and are hardly noticeable. A band of short hair around the upper part of the face with speckled colouring contrasts with the darker surrounding areas. The limbs and tail are also darkly coloured.
Populations of S. xanthosternos are restricted to the Atlantic forest of south-eastern Bahia, Brazil, due possibly to high degrees of interference from humans. Historically they probably would have inhabited the entire area east of, and north to, the Rio São Francisco.
The largest continuous area of forest in its known range, the Una Biological Reserve in Bahia, is estimated to contain a population of 185 individuals. As of 2004, there were 85 individuals in zoos and breeding facilities in Europe and Brazil.
