The white-eyelid mangabeys are African Old World monkeys belonging to the genus ''Cercocebus''. They are characterized by their bare upper eyelids, which are lighter than their facial skin colouring, and the uniformly coloured hairs of the fur. The other two genera of mangabeys, ''Lophocebus'' and ''Rungwecebus'', were once thought to be very closely related to ''Cercocebus'', so much so that all the species were placed in one genus. However, it is now understood that ''Lophocebus'' and ''Rungwecebus'' species are more closely related to the baboons in genus ''Papio'', while the ''Cercocebus'' species are more closely related to the mandrill. ==Species== *Genus ''Cercocebus'' * *Sooty mangabey, ''Cercocebus atys'' * *Collared mangabey, ''Cercocebus torquatus'' * *Agile mangabey, ''Cercocebus agilis'' * *Golden-bellied mangabey, ''Cercocebus chrysogaster'' * *Tana River mangabey, ''Cercocebus galeritus'' * *Sanje mangabey, ''Cercocebus sanjei'' 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「White-eyelid mangabey」の詳細全文を読む スポンサード リンク
