Akodon
''Akodon'' is a genus consisting of South American grass mice. They mostly occur south of the Amazon Basin and along the Andes north to Venezuela, but are absent from much of the basin itself, the far south of the continent, and the lowlands west of the Andes. ''Akodon'' is one of the most species-rich genera of Neotropical rodents. Species of ''Akodon'' are known to inhabit a variety of habitats from tropical and tropical moist forests to altiplano and desert. Fossils are known from the late Pliocene onwards. Taxonomy ''Akodon'' is the largest genus in the tribe Akodontini. Three of its synonyms—''Chalcomys'', ''Hypsimys'', and particularly ''Microxus''—have sometimes been regarded as distinct genera. Neomicroxus was separated in 2013. Previously associated with ''Akodon'', the genera ''Abrothrix'', '' Deltamys'', ''Necromys'', ''Thalpomys'', and '' Thaptomys'' are currently recognized as distinct. Some species of the tribe Abrotrichini are called akodons. The genus cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Akodon Caenosus
''Akodon caenosus'' is a rodent in the genus ''Akodon'' found in northwestern Argentina and south-central Bolivia. Since its description in 1918, it has been alternatively classified as a separate species or a subspecies of '' Akodon lutescens'' (formerly ''Akodon puer''). The species ''Akodon aliquantulus'', described from some very small Argentine specimens in 1999, is now recognized as a synonym of ''A. caenosus''. ''Akodon caenosus'' is very small, averaging in weight, and variable in coloration, but generally brown. The underparts are sharply different in color from the upperparts. The skull has a short rostrum (front part), broad interorbital region (between the eyes), and narrow braincase. The karyotype includes 34 chromosomes. ''A. caenosus'' mostly occurs in Yungas vegetation and breeds mainly during the winter. It shares its range with many other sigmodontine rodents, including three other species of ''Akodon''.

Akodon Cursor
The cursor grass mouse or cursorial akodont (''Akodon cursor''), is a sigmodontine rodent from South America. Description The cursor grass mouse is a moderately sized rodent, with a head-body length of , and a tail long. Males are larger than females, weighing an average of , compared with for females. They have a typical mouse-like appearance, with short whiskers and stubby claws on the feet. They have dark to golden brown fur over most of their body, with paler greyish or yellowish underparts. Some have a whitish spot between the ears, but this is not present on all individuals. Cursor grass mice are members of the ''A. cursor'' species group, and very similar in appearance to other members of the group. In particular, they cannot easily be distinguished from the closely related montane grass mouse, which inhabits neighbouring regions to the immediate south. Although the cursor grass mouse is, on average, slightly larger than the montane species, there is too much overlap for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Akodontini
Akodontini is the second most speciose rodent tribe of the subfamily Sigmodontinae. It includes at least 106 living species in 19 genera and is distributed mainly in the southern half of South America, with only two genera extending into Guyana (''Podoxymys'') and Venezuela (''Necromys''). It also includes genera previously placed in tribe Scapteromyini. The following genera are now generally recognized: *''Akodon'' *''Bibimys'' *'' Blarinomys'' *''Brucepattersonius'' *'' Deltamys'' *''Juscelinomys'' *''Kunsia'' *'' Lenoxus'' *''Necromys'' (previously ''Bolomys'' or ''Cabreramys'') *'' Neomicroxus'' *''Oxymycterus'' *''Podoxymys'' *''Scapteromys'' *''Thalpomys'' *'' Thaptomys'' ''Chalcomys'', ''Hypsimys'', and ''Microxus'' have been synonymized under the genus ''Akodon''.

Abrotrichini
Abrotrichini, also known as the Andean clade or southern Andean clade,Musser and Carleton, 2005, p. 1087 is a tribe of rodents in the subfamily Sigmodontinae.D'Elía et al., 2007, p. 188 It includes about fifteen species in four genera,Musser and Carleton, 2005 distributed in South America from southern Peru to southernmost South America, including the Patagonian steppes. The earliest known fossils are from the Pliocene of Argentina. Taxonomy Abrotrichines were universally placed in the tribe Akodontini until the 1990s, and some were even classified within the genus ''Akodon''. Allozyme studies in the early 1990s first provided evidence for their distinction from Akodontini, and in 1999 a study analyzing sequences of the mitochondrial cytochrome ''b'' gene found further evidence for the distinction between Akodontini and this group and proposed the name Abrotrichini for the latter.Smith and Patton, 1999, p. 106 The name Abrotrichini remained formally unavailable ...
