''Hylaeamys'' is a genus of South American oryzomyine rodents found principally in humid forested areas east of the Andes. The species in this genus have historically been placed in ''Oryzomys''. They are most closely related to ''Euryoryzomys'', ''Transandinomys'', ''Nephelomys'', ''Oecomys'', and ''Handleyomys'', and most closely resemble species of the former two genera. They are distinguished from members of ''Euryoryzomys'' by all-dark or indistinct two-tone tail coloration (as opposed to the distinct two-tone tail coloration of ''Euryoryzomys''), from members of ''Transandinomys'' by having shorter whiskers above their eyes that do not extend posteriorly behind their ears, and in both cases by differences in carotid circulation. The genus is named after ''hylaea'' ("forest" in Greek), the term used by Humboldt for the lowland South American rainforests that are the main habitat of the genus. The genus currently comprises the following species: * ''Hylaeamys acritus'' * ''Hylaeamys laticeps'' * ''Hylaeamys megacephalus'' * ''Hylaeamys oniscus'' * ''Hylaeamys perenensis'' * ''Hylaeamys tatei'' * ''Hylaeamys yunganus'' ==References== * 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「Hylaeamys」の詳細全文を読む スポンサード リンク
