Abstract

The black uakaris currently have three valid species: C. melanocephalus, C. hosomi and C. ayresi; that was proposed after group taxonomic revision but do not have consensus on this classification because of disagreements about the existence of C. ayresi proposed as new species for the group. Disagreement exists due to low phylogenetic resolution found in relation to its sister species C. hosomi due to the emergence resents these species. The specific limits of the black uakaris were tested to validate or not C. ayresi, with the use of phylogeny of Cytochrome b and next generation sequencing to delineate evolutionary lineages and biological groups. It were 10 samples of black uakaris to a new phylogenetic reconstruction Cytochrome B and 21 samples for the next generation of sequencing. All samples used in the phylogenetic reconstruction of Cytochrome b gathered with their species, indicated a reciprocal monophyly. The results from the NGS indicate that C. hosomi and C. ayresi form a single evolutionary lineage while C. melanocephalus form another lineage. Two biological groups, one composed of C. melanocephalus and other compound C. ayresi and C. hosomi were found. The results indicate that C. ayresi and C. hosomi are distinct phylogenetic species by the cytochrome b gene, following the phylogenetic species concept while from the results indicate that NGS and C. ayresi and C. hosomi form a single evolutionary lineage by not present polyphyly different species are classified by phylogenetic species concept and the same also grouped in the same biological group indicating share of the mating system and therefore classified as the same species by the biological species concept. The results indicate that C. ayresi and C. hosomi can not be classified as separate species.
