Resumen:
A new saltasaurinae dinosaur (Sauropoda, Titanosauridae) from the Río Negro Province (Allen Formation, Upper Cretaceous), Patagonia, Argentina. A new saltasaurine taxon based on a femur, pelvic bones, and dorsal and caudal vertebrae is described. The closest relationships of the new taxon are with Saltasaurus loricatus Bonaparte and Powell, 1980 from northwestern Argentina. These species share caudal vertebrae bearing a ventral depression divided by a longitudinal septum. The reord of Saltasaurinae is thus limited to the Upper Cretaceous of Argentina, with three distinct taxa: Saltasaurus loricatus, Neuquensaurus australis, and Rocasaurus muniozi gen. et sp. nov.
