Morphological, karyological, and mitochondrial DNA (cytochrome b) data indicate that Proechimys oris is likely a junior synonym of P. roberti.[2]

PhylogenyEdit

Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. roberti belongs to the so-called guyannensis group of Proechimys species, and shares closer phylogenetic affinities with the other member of this clade: P. guyannensis.[4][5][6]
