Taxonomy of theAlouatta seniculus group: Biochemical and chromosome data

Wild populations ofAlouatta belzebul andA. seniculus from Brazil were surveyed in relation to 20 protein loci. Estimates of genetic variability demonstrated thatA. seniculus presents the highest level of heterozygosity among several New World monkey species studied for the same loci. Additional information from DNA and chromosomes suggest thatA. seniculus andA. belzebul are not the closest species in theHershkovitz’sAlouatta seniculus group.
