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 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.

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 Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans. 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 spines, that presumably serve for protection from predators. Many echimyids can break off their tails when attacked. This action may confuse predators long enough for the spiny rat to es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patronym (taxonomy)
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zoolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museum Of Zoology Of The University Of São Paulo
The Museum of Zoology of the University of São Paulo ( pt, Museu de Zoologia da Universidade de São Paulo, abbreviated MZUSP) is a public natural history museum located in the historic Ipiranga district of São Paulo, Brazil. The MZUSP is an educational and research institution that is part of the University of São Paulo. The museum began at the end of the 19th century as part of the Museu Paulista; in 1941, it moved into a dedicated building. In 1969 the museum became a part of the University of São Paulo, receiving its current name. The MZUSP has one of the largest natural-history collections in Latin America, with over 8.5 million preserved specimens of vertebrates ( amphibians, mammals, birds, fish and reptiles) and invertebrates ( cnidarians, insects, crustaceans, arachnids, myriapods, annelids, mollusks and other marine groups). Each collection is curated independently, and organized according to specific needs. Other facilities in the museum include a library sp ...

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". Classification The genus contains three extant species * White-faced spiny tree-rat - ''Echimys chrysurus'' *Dark spiny tree-rat - ''Echimys saturnus'' * Vieira's spiny tree-rat - ''Echimys vieirai'' Members of the genera ''Callistomys'', '' Makalata'', ''Pattonomys'', and ''Phyllomys ''Phyllomys'' is a genus of arboreal spiny rat, geographically restricted to the forests of eastern Brazil.

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. The etymology of the species name derives from the two ancient greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC.

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. 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 ''Echimys vieirai'' is a spiny rat species from South America, described in 2005. It is found in Brazil.

Mammals Described In 2005
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, pinniped, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, tog ...
