Proechimys
''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 (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 ''Trinomys'' with 11 species. Phylogeny Genus level The genus ''Proechimys'' is the sister group to the genus ''Hoplomys'' (the armored rat). In turn, these two taxa share evolutionary affinities with other Myocastorini genera: ''Callistomys'' (the painted tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proechimys Semispinosus
Tome's spiny rat (''Proechimys semispinosus''), also known as Tomes' spiny rat or the Central American spiny rat, is a species of spiny rat distributed from Honduras to Ecuador. The IUCN has assessed its conservation status as being of "least concern". Description Tome's spiny rat is a large rat with a head-and-body length of between and a tail length of between . The head is long and slender, with prominent eyes and narrow erect ears. At night, the eyes reflect a reddish eyeshine. The feet are long with strong nails. The pelage is sleek with spines mixed in with the dorsal fur, though these are not very obvious in the field. The upper parts are reddish-brown while the underparts are white. The tail is almost hairless and is reddish-brown above and white below. About 20% of animals encountered have no tail. This rat could be confused with the armored rat (''Hoplomys gymnurus'') which is much the same size, but the armored rat has a longer snout and smaller eyes, which are ...

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. Distribution and habitat This species has a range in South America extending from southern Bolivia and northern Paraguay to western and central Brazil. It is terrestrial and inhabits dry primary and secondary forest, as well as cerrado and habitats with cleared areas and patches of forest. It usually occurs at altitudes below but has been reco ...
