Discussion: Patterson and Pascual (1968 b: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.
