Ugandan Crested Mangabey

The Uganda mangabey (Lophocebus albigena ugandae) is a subspecies of the grey-cheeked mangabey (L. albigena), an Old World monkey, found only in Uganda and in the Minziro Forest Reserve, just over the border in Tanzania. Colin Groves upgraded the Ugandan population of this crested mangabey to the new species L. ugandae on 16 February 2007, but this is not widely accepted. This subspecies is significantly smaller than the other subspecies of grey-cheeked mangabey, with a shorter skull and smaller face. 2018 was the most recent year in which the International Union for Conservation of Nature assessed the conservation status of L. albigena ugandae, describing it as being of vulnerable. == Taxonomy == In 1978, Colin Groves recognized three subspecies of Lophocebus albigena, namely L. a. albigena; L. a. johnstoni; and L. a. osmani. Three decades later, in 2007, he raised these subspecies to full species rank on phylogenetic grounds, at the same time recognising that the mangabeys present in Uganda were sufficiently different from the remainder of L. albigena as to constitute a separate species, which he named L. ugandae. The IUCN continues to list these all as subspecies. == Description == The Uganda mangabey is rather smaller than the…
