Species of mammals belonging to the spiny rat family of rodents
The Guaira spiny-rat (Proechimys guairae ) is a species of
rodent in the family
Echimyidae .
[2] It is
endemic to
Venezuela . It is commonly referred to as 'casiragua' to avoid confusion with true rats (
Muroidea )
[3]
Phylogeny
Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. guairae belongs to the so-called trinitatus group of Proechimys species, and shares closer phylogenetic affinities with the other members of this clade:
P. trinitatus ,
P. mincae ,
P. poliopus ,
P. magdalenae ,
P. chrysaeolus ,
P. urichi , and
P. hoplomyoides .

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