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]
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.
