Phylogenetic relationships among some Ateles species: the use of chromosomic and molecular characters

As with most platyrrhines, the systematics of Ateles is under discussion. In order to help clarify its systematic, we employed chromosomic and molecular characters to analyze the phylogenetic relationship among some species of the genus Ateles.

Description
Summary:As with most platyrrhines, the systematics of Ateles is under discussion. In order to help clarify its systematic, we employed chromosomic and molecular characters to analyze the phylogenetic relationship among some species of the genus Ateles. Chromosomic studies were conducted on 14 atelid specimens: eight Ateles from A. paniscus, A. chamek, A. belzebuth and A. geoffroyi, and six Alouatta caraya. Ateles paniscus showed 2N=32, whereas A. chamek, A. belzebuth and A. geoffroyi presented 2N=34, XX/XY (with a submetacentric X and a variable Y) corroborated by male meiosis. Nucleotide sequence variation at the mitochondrial cytochrome c oxidase subunit II gene (COII) was analyzed in ten New World monkey specimens. Parsimony trees showed consistent phylogenetic relationships using both chromosomic forms and mitochondrial COII gene sequences as characters. Particularly, chromosomic phylogenies showed A. hybridus as a divergent taxon from the remaining group, whereas A. chamek, A. belzebuth and A. marginatus form an unresolved clade with A. geoffroyi as sister group.
