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.
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 .
