New material, including associated skulls and lower jaws and postcranial bone remains from early Pleistocene San Andresian beds of southeastern Buenos Aires Province, demonstrates that the octodontine rodent Pseudoplataeomys castellanosi differs strongly from the type and referred species of Pseudoplataeomys. P. castellanosi is proposed as the type species of a new monotypic genus. The new genus is considered as closly related to, more primitive than, and probably ancestral to extant Octodon. -Authors
