West Indian primates have at times been divided into as many as two families, five genera, and five species. More recent reviews point to a single radiation of three monotypic genera in a single endemic family, the Xenotrichidae. One endemic genus is thus recognized on each of the islands of Cuba, Hispaniola, and Jamaica. Whether the absence of an endemic primate on Puerto Rico is real or an artifact of the scarce fossil record of these animals is as yet unknown.  All living primates in the West Indies are Old World introductions of the modern era.
