Gracile capuchin monkeys are
capuchin monkeys in the genus
Cebus. At one time all capuchin monkeys were included within the genus
Cebus. In 2011, Jessica Lynch Alfaro
et al proposed splitting the genus between the
robust capuchin monkeys, such as the
tufted capuchin, and the gracile capuchins. The gracile capuchins retain the genus name
Cebus, while the robust species have been transferred to
Sapajus.
