Species of mammals belonging to the spiny rat family of rodents
The stiff-spine spiny-rat (Proechimys echinothrix Tefe spiny rat , is a spiny rat species[ 2] 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]
