Cheracebus is a new genus of New World primate of the family Pitheciidae, subfamily Callicebinae. Until recently, Cheracebus was classified as the torquatus species group of the genus Callicebus . The genus Cheracebus has six species: C. lucifer, C. lugens, C. regulus, C. medemi, C. torquatus , and C. purinus , which are all endemic to the Amazon biome. Before the present study, there had been no conclusive interpretation of the phylogenetic relationships among most of the Cheracebus species. The present study tests the monophyly of the genus and investigates the relationships among the different Cheracebus species, based on DNA sequencing of 16 mitochondrial and nuclear markers. The phylogenetic analyses were based on Maximum Likelihood, Bayesian Inference, and multispecies coalescent approaches. The divergence times and genetic distances between the Cheracebus taxa were also estimated. The analyses confirmed the monophyly of the genus and a well‐supported topology, with the following arrangement: (( C. torquatus, C. lugens ), ( C. lucifer ( C. purinus, C. regulus ))). A well‐differentiated clade was also identified within part of the geographic range of C. lugens , which warrants further investigation to confirm its taxonomic status.
