A wild population situated in the border of the distributions of Saimiri sciureus macrodon and S. boliviensis peruviensis, in the Peruvian Amazonia, was studied in relation to 22 protein loci. These genetic markers provided indications of secondary intergradation between these two taxa, reinforcing previous morphological and cytogenetic evidences. Continued studies in this region on the hybrids' viability and fertility may be important for decisions related to the taxonomy of this genus. © 1992 Japan Monkey Centre.
