Phylogeny

Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. cuvieri belongs to the so-called longicaudatus group of Proechimys species, and shares closer phylogenetic affinities with the other members of this clade: P. longicaudatus and P. brevicauda.^[2][3][4][5]
