 In turn, this clade shares phylogenetic affinities with a subfamily of spiny rats, the Euryzygomatomyinae.Within Capromyidae, the deepest split involves "Plagiodontia" with respect to other genera, followed by the divergence of "Geocapromys".The latter genus is the sister group to a clade in which "Capromys" branches off before the "Mesocapromys" and "Mysateles" split.
