Patton's spiny rat

Patton's spiny-rat (Proechimys pattoni) is a spiny rat species found in Brazil and Peru.

Phylogeny
Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. pattoni belongs to the so-called gardneri group of Proechimys species. Within this clade, Proechimys pattoni is more closely related to P. gardneri than to P. kulinae.
