Roberto's spiny-rat (Proechimys roberti) or Para spiny rat, is a spiny rat species [3] found in Brazil.

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

Phylogeny

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]
