The Trinidad spiny rat (Proechimys trinitatis[2][3]) is a species of rodent in the family Echimyidae. It is found in Trinidad and Tobago and northern Venezuela.

Phylogeny

Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. trinitatus belongs to the so-called trinitatus group of Proechimys species, and shares closer phylogenetic affinities with the other members of this clade: P. mincae, P. guairae, P. poliopus, P. magdalenae, P. chrysaeolus, P. urichi, and P. hoplomyoides.[4][5][6][7]

Species-level cladogram of the genus Proechimys.
The cladogram has been reconstructed from morphological characters and mitochondrial DNA (cytochrome b) sequences.[4][5][6][7]
