Robert's spiny rat explained

Robert's spiny-rat (Proechimys roberti) or Para spiny rat, is a spiny rat species found in Brazil. This species is named after the collector Alphonso Robert, who collected the holotype of this species in 1901. ^[1]

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.^{[3] [4] [5]}
