摘要：We here describe a prosimian specimen discovered from the early Middle Miocene (~15 Ma) of Nachola, northern Kenya. It is a right maxilla that preserves P4–M3, and is assigned to a new species of the Miocene lorisid genus Mioeuoticus . Previously, Mioeuoticus was known from the Early Miocene of East Africa. The Nachola specimen is therefore the first discovery of this genus from the Middle Miocene. The presence of a new lorisid species in the Nachola fauna indicates a forested paleoenvironment for this locality, consistent with previously known evidence including the abundance of large-bodied hominoid fossils ( Nacholapithecus kerioi ), the dominance of browsers among the herbivore fauna, and the presence of plenty of petrified wood.
