Echimys
''Echimys'' is a genus of the spiny rats family, the Echimyidae. Members of this genus are collectively called spiny tree-rats. The genus name ''Echimys'', and also its synonym ''Echinomys'', derive from the two Ancient Greek words (), meaning "hedgehog", and (), meaning "mouse, rat".

Echimys Chrysurus
The white-faced spiny tree-rat (''Echimys chrysurus'') is a spiny rat species from South America. It is found in Brazil, French Guiana, Guyana and Suriname.

Echimys Saturnus
The dark spiny tree-rat (''Echimys saturnus'') is a species of rodent in the family Echimyidae. It is a rarely encountered and nocturnal species, found in eastern Ecuador and central Peru.

Echimys Vieirai
''Echimys vieirai'' is a spiny rat species from South America, described in 2005. It is found in Brazil. The species name ''vieirai'' is a patronym for the Brazilian mammalogist Carlos Octaviano da Cunha Vieira, curator of the Mammal Collection at the Museum of Zoology of the University of São Paulo (MZUSP), from the early 1940s to 1958. The main diagnostic trait of this ''Echimys'' species is the presence of a dorsal median dark maroon stripe on the head. As compared to ''Echimys chrysurus'', ''E. vieirai'' also possesses a darker dorsum. In addition, ''E. vieirai'' can be distinguished from ''Echimys saturnus The dark spiny tree-rat (''Echimys saturnus'') is a species of rodent in the family Echimyidae.

Echimyini
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. Phylogeny Five assemblages can be distinguished in the genus-level cladogram of Echimyini: * ''Echimys'' is closely related to ''Phyllomys'', ''Makalata'', ''Pattonomys'' and ''Toromys''.

Phyllomys
''Phyllomys'' is a genus of arboreal Echimyidae, spiny rat, geographically restricted to the forests of eastern Brazil. The etymology of the genus name derives from the two ancient greek words (), meaning "plant leaf", and (), meaning "mouse, rat". Phylogeny ''Phyllomys'' is the sister genus to ''Echimys'', and then to ''Makalata''. These taxa are closely related to the genera ''Pattonomys'' and ''Toromys''. In turn, these five genera share phylogenetic affinities with a clade containing the bamboo rats ''Dactylomys'', ''Olallamys'', ''Kannabateomys'' together with ''Diplomys'' and ''Santamartamys''. Systematics There are thirteen named species in the genus. These species have frequently been placed in the genus ''Echimys''. *''Phyllomys blainvilii'' – golden Atlantic tree-rat *''Phyllomys brasiliensis'' – orange-brown Atlantic tree-rat *''Phyllomys dasythrix'' – drab Atlantic tree-rat *''Phyllomys kerri'' – Kerr's Atlantic tree-rat *''Phyllomys lamarum'' – p ...

Echimyidae
Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the West Indies in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles. Characteristics In general form, most spiny rats resemble rats, although they are more closely related to guinea pigs and chinchillas. Most species have stiff, pointed hairs, or Spine (zoology), spines, that presumably serve for protection from predators. Many echimyids can Autotomy, break off their tails when attacked. This action may confuse predators long enough for the spiny rat to escape. Unlike the tai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makalata
''Makalata'' is a genus of rodents in the family Echimyidae. Systematics The etymology of this genus name derives from a combination of letters inspired by the Suriname Suriname, officially the Republic of Suriname, is a country in northern South America, also considered as part of the Caribbean and the West Indies. It is a developing country with a Human Development Index, high level of human development; i ... native name ''Maka-alata'' for spiny rats. This genus contains the following species: * Brazilian spiny tree-rat ('' Makalata didelphoides'') * Long-tailed armored tree-rat ('' Makalata macrura'') * Dusky spiny tree-rat ('' Makalata obscura'') * Peruvian tree-rat ('' Makalata rhipidura'') Phylogeny ''Makalata'' is the sister genus to ''Echimys'' and ''Phyllomys''. These taxa are closely related to the genera ''Pattonomys'' and ''Toromys'', reflecting the fact '' Pattonomys occasius'' and '' Toromys grandis'' have been placed in ''Makalata'' by some authorities.

Callistomys
The painted tree-rat (''Callistomys pictus'') is a species of spiny rat from Brazil, restricted to north-eastern Bahia in eastern Brazil. It is the only species in the genus ''Callistomys''. Identification With a total length of ca. , it is a relatively large species of spiny rat. It is white with a strongly contrasting glossy-black cap, back and band down towards its forelimbs. Its long fur is dense and coarse, but not spiny, as in some other members of its family. Specimens often have brown (rather than black) markings, but as far as it is known this is caused by fading and does not occur in the living animals. Owing to its striking black-and-white pelage, it is virtually unmistakable, but could perhaps be confused with a hairy dwarf porcupine ('' Coendou'' spp.) – all of which have spines and lack the distinctive pattern of the painted tree-rat. Etymology * The genus name ''Callistomys'' derives from the two ancient greek words () meaning "very beautiful", — i.e., thi ...
