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.[4][5][6][7]

Species-level cladogram of the genus Proechimys.

The cladogram has been reconstructed from morphological characters and mitochondrial DNA (cytochrome b) sequences.[4][5][6][7]
