Species of mammals belonging to the spiny rat family of rodents
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
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.
