Proechimys
''Proechimys'' is a genus of South American South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o ... 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 (or aristiforms) — hence the vernacular name of spiny rats — and soft hairs (or setiforms). ''Proechimys'' is the most speciose genus of the rodent family Echimyidae, with 25 species recognized, followed by '' Phyllomys'' with 13 species, and '' Tri ...

Proechimys Longicaudatus
The long-tailed spiny rat (''Proechimys longicaudatus'') is a spiny rat species found in Bolivia, Brazil and Paraguay. Description The long-tailed spiny rat is a large rat with a head-and-body length of between and a tail length of . The fur is less bristly than in other related species. The upper parts are a glossy chestnut colour becoming more orange on the flanks. The underparts are white, and there is a clear line separating upper and lower parts. The tail is chestnut above and pale below. The tails are missing on some individuals, reflecting the lizard-like ability of many echimyids to detach their tails when attacked by predators.
