Tamarins of the genus Saguinus, subfamily Callitrichinae, represent one of the most diverse primate radiations. So far, about 35 taxa have been described, but detailed information about their taxonomy and phylogeny is still lacking. To further elucidate the phylogenetic relationships and the biogeographic history within the genus, and to contribute to a more reliable classification of its taxa, we sequenced the complete mitochondrial cytochrome b gene and the hypervariable region I of the D-loop. Therefore, we mainly used fecal samples from wild tamarins collected during two expeditions to the Peruvian Amazon, an area of high tamarin diversity. Our data suggest that the numerous taxa of the S. nigricollis species group are derived from a common ancestor that separated from the other representatives of the genus ∼10 mya. Most taxa of the S. nigricollis group form monophyletic clusters, which mainly originated in a single rapid radiation ∼2.9 mya. S. fuscicollis and S. nigricollis appear as polyphyletic taxa, but we could identify various clusters, which are mainly consistent with differences in coat coloration. We could confirm most of the existing taxa as distinct entities and suggest species status for fuscicollis, illigeri, lagonotus, leucogenys, nigricollis, nigrifrons, tripartitus, and weddelli. Our genetic data do not support a separate status for melanoleucus and graellsi, but due to differences in fur coloration, we give them subspecies status. The species group most likely originated in western Amazonia and diversified during the decline of the Acre wetland and the formation of the Amazonian river system.
