Due to similar cranial morphology, the nutria was once considered a close relative of the Caribbean hutias and placed together with them in the family Capromyidae.[1] Later, it was more accepted to place it in its own family, the Myocastoridae.[2] Recent molecular studies place them in the family Echimyidae, in the tribe Myocastorini.[3][4][5]
Fossil record
Kerber et al. (2013) recognize the following species as valid:[6]
Myocastor columnaris (Middle Pleistocene)
Myocastor obesus (Late Miocene)
Myocastor paranensis (Late Miocene)
Other species described but no longer considered valid include Myocastor minor, Myocastor perditus, and Myocastor priscus.
