Oreoryzomys
''Oreoryzomys balneator'', also known as the Peruvian rice rat〔 or Ecuadoran Oryzomys,〔Musser and Carleton, 2005〕 is a species of rodent in the tribe Oryzomyini of family Cricetidae. It is found in Ecuador and northern Peru in cloud forest at elevations from 1500 to 1800 m.〔 It is the only species in the genus ''Oreoryzomys'', which was included in ''Oryzomys'' until 2006.〔Weksler et al., 2006〕 The genus name ''Oreoryzomys'' is a combination of ορος the Greek word for "mountain" with the old genus name ''Oryzomys'' and refers to the mountainous habitat of ''O. balneator''. Recent research suggests that ''O. balneator'' is not closely related to ''Oryzomys'', but instead is probably related to ''Microryzomys'' within a clade also including ''Neacomys'' and ''Oligoryzomys''. The back is olive brown and the belly fur white or yellow, with a sharp separation. The ears are short. At the base of the claws on the hind feet are tufts of hair. The long tail is sometimes a little darker on the upper side than on the bottom. ==References==
