Myocastor Kerr, 1792 . Anim. Kingdom, p. 225.

COMMENT: Myocastor is not a capromyid and was referred to the Family Myocastoridae Ameghino, 1904, by Woods and Howland, 1979, J. Mammal., 60: 114. Although Patterson and Pasqual, 1968, Breviora, 301:6, included Myocastor and several fossil forms as the subfamily Myocastorinae of the Echimyidae, it is generally agreed that Myocastor is not an echimyid (GSM). Includes Myopotamus; see Cabrera, 1958:569.
