The dark spiny tree-rat (Echimys saturnus) is a species of rodent in the family Echimyidae. [2] It is a rarely encountered and nocturnal species, found in eastern Ecuador and central Peru. [3] [4]
Compared to Echimys chrysurus , the main diagnostic character state of this Echimys species is the mostly black dorsal part of the head and body. In addition, E. saturnus can be distinguished from Echimys vieirai by possessing a venter spotted with white while it is uniformly grayish brown in the latter species. [5]

Phyllomys is a genus of arboreal spiny rat, geographically restricted to the forests of eastern Brazil.
Echimys is a genus of the spiny rats family, the Echimyidae. Members of this genus are collectively called spiny tree-rats.
Dactylomys is the genus of South American bamboo rats They are arboreal members of the family Echimyidae.
Olallamys is a genus of Andean soft-furred spiny rat that range from Panama through Colombia and Venezuela to northern Ecuador. These species are typically found at elevations above 2,000 metres (6,600 ft).
Diplomys is a genus of rodent in the family Echimyidae. They are found in Costa Rica, Ecuador, Colombia and Panama.
The rufous soft-furred spiny-rat, known as ratón espinoso meaning "spiny" or "thorny" rat in Spanish, is a species of rodent in the family Echimyidae. It is found in Colombia, Ecuador, and Panama. In November 2015, it was spotted for the first time in Osa, Costa Rica by the Costa Rican researcher Jim Córdoba-Alfaro.
The red-crested tree-rat or Santa Marta toro is a species of tree-rat found in the monotypic genus Santamartamys in the family Echimyidae. It is nocturnal and is believed to feed on plant matter, and is mainly rufous, with young specimens having a grey coat. IUCN list the species as critically endangered: it is affected by feral cats, climate change, and the clearing of forest in its potential range in coastal Colombia.
The armored rat is a species of rodent in the family Echimyidae. It is monotypic within the genus Hoplomys. It is found in Latin America, from northern Honduras to northwest Ecuador. It possesses a range of spines on its back and sides of the body.
Makalata is a genus of rodents in the family Echimyidae.
The Brazilian spiny tree rat is a species of rodent in the family Echimyidae. It is found in Bolivia, Brazil, French Guiana, Guyana, Suriname, Venezuela, and Trinidad and Tobago where it lives in lowland tropical rainforest. There is also a population in Ecuador which is referable either to this species or to Makalata macrurus. It is nocturnal, and eats seeds.
Pattonomys is a genus of rodent in the family Echimyidae, named after American mammalogist James L. Patton. It contains the following species:
Echimyini is a tribe of echimyid rodents, proposed in 2016, and containing 13 extant genera: all of the tree rats Echimys, Phyllomys, Makalata, Pattonomys, Toromys, Diplomys, Santamartamys, and Isothrix, the long recognized dactylomines Dactylomys, Olallamys, and Kannabateomys, and the enigmatic and previously classified as eumysopines Lonchothrix and Mesomys. All these spiny rats genera are arboreal. Worth of note, the arboreal genus Callistomys – the painted-tree rat – does not belong to the tribe Echimyini. Because it is phylogenetically closer to Myocastor, Hoplomys, Proechimys, and Thrichomys than to the above-mentioned Echimyini genera, it is classified in the tribe Myocastorini.
Echimys vieirai is a spiny rat species from South America, described in 2005. It is found in Brazil.
