Silvery greater galago

The silvery greater galago, Otolemur monteiri, is a nocturnal primate of the galago family, Galagidae, found mainly in Brachystegia woodland from Angola to Tanzania, western Kenya and Rwanda. It was separated from the brown greater galago as a species by the primatologist Colin Groves in 2001, a split that also placed a form named O. m. argentatus within it as a subspecies. The International Union for Conservation of Nature and the American Society of Mammalogists have not followed that split and still treat the silvery greater galago as a subspecies of the brown greater galago, Otolemur crassicaudatus monteiri, so its rank depends on which authority a reader follows. It is listed here as a species because its own encyclopedia article and the Galagidae family article list it that way.
