The Guyanan spiny-rat (Proechimys hoplomyoides) is a spiny rat species found in Brazil, Guyana and Venezuela. The species was first described by George Henry Hamilton Tate in 1939.
Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. hoplomyoides belongs to the so-called trinitatus group of species of Proechimys, and shares closer phylogenetic affinities with the other members of this clade: P. trinitatus , P. mincae , P. guairae , P. poliopus , P. magdalenae , P. chrysaeolus , and P. urichi .
