Black-striped capuchin

The black-striped capuchin (Sapajus libidinosus), also known as the bearded capuchin,[2] is a capuchin monkey from South America. It was the first non-ape primate in which tool usage was documented in the wild, as individuals have been seen cracking nuts by placing them on a stone "anvil" while hitting them with another large stone.[3] Adaptations to carrying large stones and fruit include strengthened back and leg muscles that permit the monkey to walk on its hind legs while carrying stones.[4] The black-striped capuchin has traditionally been considered a subspecies of the tufted capuchin.[1] On the contrary, the southern population here included in S. libidinosus has sometimes been considered another species, Azaras's capuchin (S. cay) (syn. S. paraguayanus).[5]

The black-striped capuchin is found in the Caatinga, Cerrado, and Pantanal of Brazil.[2] Some confusion surrounds the taxon juruanus, here included as a subspecies of the black-striped capuchin.[2] It has been considered to occur from the upper Juruá River east and south to Mato Grosso,[6] or alternatively entirely restricted to the region near the upper Juruá River.[7] In the latter case, its range would be surrounded by C. apella, leading to doubts over its true taxonomic status.[8]

Groves (2005) recognizes four subspecies:[1]

  • Cebus libidinosus libidinosus
  • Cebus libidinosus pallidus
  • Cebus libidinosus paraguayanus
  • Cebus libidinosus juruanus

In 2011, Jessica Lynch Alfaro et al. proposed that the robust capuchins such (formerly the C. apella group) be placed in a separate genus, Sapajus, from the gracile capuchins (formerly the C. capucinus group), which retain the genus Cebus.[9][10]
