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.

Phylogeny

[edit]

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.[2][3][4][5]
