Proechimys decumanus (Thomas, 1899)
|
The Pacific spiny rat (Proechimys decumanus) is a species of rodent in the family Echimyidae.[2] It is found in Ecuador and Peru.
Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. decumanus represents one independent evolutionary lineage within the genus Proechimys, without clear phylogenetic affinity for any of the 6 major groups of species.[3][4]
