Interspecific relationships ofCallithrix based on the dental characters

  • Masahito Natori


The dental structure of all species ofCallithrix, C. argentata, C. humeralifer, C. aurita, C. flaviceps, C. geoffroyi, C. penicillata, andC. jacchus is examined.Callithrix are divided intoC. jacchus group andC. argentata group, based on the analysis of dental characters.C. jacchus group consists ofC. jacchus, C. penicillata, C. geoffroyi, C. flaviceps, andC. aurita, whileC. argentata andC. humeralifer are assigned toC. argentata group. InC. jacchus group,C. aurita andC. flaviceps were differentiated from the original stock of their common ancestor, followed byC. geoffroyi, last byC. penicillata, and finallyC. jacchus. Based on the relationships among species ofCallithrix, it is possible to infer the relative age of the formation of the refuges which caused their speciation. First, the forests in southeastern Brazilian coast were split from Amazonia. In southeastern Brazilian coast, the Paulista center separated, followed by the Rio Doce center, the Bahia center, finally by the Pernambuco center.
