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 .

<i>Proechimys</i> Genus of mammals belonging to the spiny rat family of rodents

Proechimys is a genus of South American spiny rats of the family Echimyidae. All species of the genus are terrestrial. In the lowland Neotropical forests, Proechimys rodents are often the most abundant non-volant mammals. They are recognizable by reason of their elongated heads and long rostra, large and erect ears, narrow and long hind feet, and tails always shorter than head-and-body lengths. The dorsal pelage comprises a mixture of expanded, varyingly stiffened spines — hence the vernacular name of spiny rats — and soft hairs.
