Roberto's spiny rat


Roberto's spiny-rat, Proechimys roberti, or Para spiny rat, is a spiny rat species from South America. It is found in Brazil.
Morphological, karyological, and mitochondrial DNA data indicate that Proechimys oris is likely a junior synonym of P. roberti.

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.
