Robert's spiny-rat (Proechimys roberti) or Para spiny rat, is a spiny rat species 3 found in Brazil. This species is named after the collector Alphonso Robert, who collected the holotype of this species in 1901.4

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.567
