The stiff-spine spiny-rat (Proechimys echinothrix) or Tefe spiny rat, is a spiny rat species[2] found in Brazil and Colombia.

Phylogeny

Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. echinothrix represents one independent evolutionary lineage within the genus Proechimys, without clear phylogenetic affinity for any of the 6 major groups of species.[3][2][4][5]

Species-level cladogram of the genus Proechimys.
The cladogram has been reconstructed from morphological characters and mitochondrial DNA (cytochrome b) sequences.[3][2][4][5]
