Handleyomys
''Handleyomys'' is a genus of Central America, Central and South American rodents in the tribe Oryzomyini of family Cricetidae. It was first described in 2002 to include two species from the Colombian Andes which were previously included in distinct and unrelated genera, ''Aepeomys'' and ''Oryzomys'', but which turned out to be closely related. Later, in 2006, six other species were provisionally added from ''Oryzomys''; these are expected to be placed in new genera in the future. The genus is named after Charles O. Handley Jr., the eminent mammalogist from the National Museum of Natural History, National Museum, Smithsonian Institution. The genus now includes the following species: *''Handleyomys alfaroi'' *''Handleyomys chapmani'' *''Handleyomys fuscatus'' *''Handleyomys intectus'' *''Handleyomys melanotis'' *''Handleyomys rhabdops'' *''Handleyomys rostratus'' *''Handleyomys saturatior'' Literature cited * * Handleyomys, Rodent genera {{Sigmodontinae-stub ...

Handleyomys Rostratus
''Handleyomys rostratus'', also known as the long-nosed oryzomys, long-nosed rice rat, or rusty rice rat is a species of rodent in the genus ''Handleyomys'' of family Cricetidae. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. It is nocturnal and is found in forests at elevations above sea level to 1200 meters. ''Handleyomys rostratus'' attains its highest level of development in south and Central America. High rates of deforestation and habitat destruction Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ... are the biggest threat to ''Handleyomys rostratus''.

Handleyomys Intectus
The Colombian rice rat (''Handleyomys intectus''), also known as the white-footed Handley's mouse is a species of rodent in the family Cricetidae occurring only in Colombia. It was previously included in ''Oryzomys'', but closely resembles the dusky montane rat, and accordingly both species were placed in the new genus ''Handleyomys'' in 2002. Description This is a medium-sized rat, with adults measuring in head-body length, with a tail of about the same length, and weighing from . The fur is soft and brownish-grey over most of the body, gradually fading to a grizzled dark grey on the underparts. Unlike its closest relative, the dusky montane rat, the almost-hairless tail has the same dark colour on both upper and lower surfaces, and unlike most other related species, the female has only six teats, instead of eight. It has no gall bladder. Distribution and habitat The Colombian rice rat is found only in the Cordillera Central in northwestern Colombia, from Antioquia Departmen ...

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, '' Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included '' Oligoryzomys'', '' Oecomys'', and '' Oryzomys'' (which included many species now in other genera), as well as '' Rhagomys'', which is currently classi ...

Oryzomys
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and ''Oryzomys couesi, O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful Taxonomy (biology), taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
