Myocastor adalah genus hewan pengerat yang mencakup nutria (atau coypu) yang masih hidup, serta beberapa spesies fosil (punah).

Taksonomi

Karena morfologi kranium mereka yang serupa, nutria awalnya dianggap sebagai kerabat dekat hutia dari kepulauan Karibia, ditempatkan bersama dalam famili Capromyidae.^[1] Belakangan, dipindahkan ke familinya sendiri, Myocastoridae.^[2] Studi molekuler terkini menempatkannya pada famili Echimyidae, dalam tribus Myocastorini.^[3][4][5]

Catatan fosil

Kerber et al. (2013) mengakui spesies tersebut sebagai sah:^[6]

• Myocastor columnaris (Pleistosen Tengah)
• Myocastor obesus (Miosen Akhir)
• Myocastor paranensis (Miosen Akhir)

Spesies lain yang dideskripsikan namun sekarang tidak sah mecakup Myocastor minor, Myocastor perditus, and Myocastor priscus.
