GENUS Myocastor

Author:Kerr, 1792.
Citation:InLinnaeus, Anim. Kingdom: 225.
Type Species:Mus coypus Molina, 1782.
Comments:Patterson and Pascual (1968b:6) included Myocastor and several fossil forms as the subfamily Myocastorinae of the Echimyidae. Based on sequence data, the sister taxon of Myocastor appears to be Capromys (Leite and Patton, 2002). Although this sister taxon relationship is well supported in both parsimony and maximum likelihood analyses (Leite and Patton, 2002), potential problems including taxon bias and long branch attraction have not been fully addressed.
