Objectives: The purpose of this work is to present a new primate locality with evidence thatincreases the knowledge on the radiation of the extinct platyrrhine primates.Materials and methods: We studied the new specimen and compared it to specimens identifiedas Mazzonicebus almendrae.Results: The new first and second molars were comparable to Mazzonicebus almendrae in all morphologicaldetails, allowing us to allocate the new specimen to M. almendrae and add commentson morphological variation in this species regarding the orientation of the labial cristae and developmentof the anterolingual cingulum. This new maxilla also present the first known M3 for thespecies.Discussion: The new specimen increases our knowledge of the extinct platyrrhines from Patagonia.Their age and geographical distribution ranges from early to middle Miocene in an areabetween 408 to 478 of southern latitude.
