''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. 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 contains the following species:〔Musser and Carleton, 2005, pp. 1092–1100〕 *''Akodon aerosus'' *''Akodon affinis'' *''Akodon albiventer'' *''Akodon azarae'' *''Akodon bogotensis'' *''Akodon boliviensis'' *''Akodon budini'' *''Akodon caenosus'' *''Akodon cursor'' *''Akodon dayi'' *''Akodon dolores'' *''Akodon fumeus'' *''Akodon glaucinus'' *''Akodon iniscatus'' *''Akodon juninensis'' *''Akodon kofordi'' *''Akodon latebricola'' *''Akodon lindberghi'' *''Akodon lutescens'' *''Akodon mimus'' *''Akodon mollis'' *''Akodon montensis'' *''Akodon mystax'' *''Akodon neocenus'' *''Akodon orophilus'' *''Akodon paranaensis'' *''Akodon pervalens'' *''Akodon philipmyersi'' *''Akodon polopi'' *''Akodon reigi'' *''Akodon sanctipaulensis'' *''Akodon serrensis'' *''Akodon siberiae'' *''Akodon simulator'' *''Akodon spegazzinii'' *''Akodon subfuscus'' *''Akodon surdus'' *''Akodon sylvanus'' *''Akodon tartareus''〔 *''Akodon toba'' *''Akodon torques'' *''Akodon varius'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Akodon」の詳細全文を読む スポンサード リンク
