We here describe a prosimian specimen discovered from the early Middle Miocene (similar to 15 Ma) of Nachola, northern Kenya. It is a right maxilla that preserves P-4-M-3, 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.
