Table 5 summarizes the mean pairwise genetic distances
among the taxa included in this study. As expected, the mean distance
between species of spider monkeys is smaller than the distance
between either Callicebus, Cebus, Alouatta, or Lagothrix and
all of the individual spider monkey taxa. Genetic distances
between different species of spider monkeys range from 0.020 to
0.084. The shortest genetic distance found between two spider
monkey species was between A. belzebuth and A. chamek, while
the largest was between A. marginatus and A. fusciceps
