The Honda Group of La Venta, Colombia, has yielded a wide array of crown platyrrhine primates, documenting the late Middle Miocene epoch (ca. 13.1–12.6 Ma, Laventan South American Land Mammal Age). Although exceptional, this record represents only a snapshot of the evolutionary history of New World monkeys because virtually none of the primate taxa recorded at La Venta had so far been found elsewhere. We describe here few dental remains of a cebine platyrrhine discovered from Laventan deposits in the San Martín Department of Peru (Peruvian Amazonia). The primate dental specimens from that new fossil-bearing locality (TAR-31) are strongly reminiscent morphologically of the teeth of Neosaimiri fieldsi from La Venta. However, given that several aspects of the dental variability from TAR-31 are unknown, we prefer to provide an assignment with open nomenclature (i.e., N. cf. fieldsi), instead of formally referring these remains to N. fieldsi, pending the discovery of additional specimens. The occurrence of Neosaimiri in Peru, in coeval deposits of La Venta, thus represents a second and southernmost record of that low-latitude genus in the Neotropics, thereby demonstrating its wide distribution along the northwestern edge of the Pebas Mega-Wetland System, in tropical western South America.

The 2018 field expedition (August/September) in the San Martín Department of Peru and postfield analyses (2018–2019) were carried out, thanks to the support from The Leakey Foundation. Fieldwork in that region was also supported by the National Geographic Society, an ‘Investissements d’Avenir’ grant managed by the French Agence Nationale de la Recherche (CEBA, ANR-10-LABX-25-01), and by the CoopIntEER CNRS/CONICET (n° 252540) and the ECOS-Sud/FONCyT (n° A-14U01) international collaboration programs. Paleontological investigations in Peruvian Amazonia are carried out in the framework of an ongoing collaboration agreement between the Museo de Historia Natural de la Universidad Nacional Mayor San Marcos (Lima, Peru) and the Institut des Sciences de l’Évolution de Montpellier-Université de Montpellier, France.
