Taxonomy notes

was proposed as a new name for the part of the species previously known as C. melanocephalus by Boubli, et al., which was later reverted by Ferrari, et al who considered it as melanocephalus ayresi; both changes are controversial, but recent literature and the IUCN have favored the decision to use C. ayresi; because of the controversy surrounding this opinionated taxonomic decision, some authors have opted to retain only a single species, C. melanocephalus, including ouakary, hosomi, and ayresi as synonyms
