See text The crested mangabeys are West African Old World monkeys belonging to the genus Lophocebus.

However, Lophocebus species are now understood to be more closely related to the baboons in genus Papio, while the Cercocebus species are more closely related to the mandrill.

In 2006, the highland mangabey was moved from Lophocebus to a new genus, Rungwecebus.

In 2007, Colin Groves described a new subspecies and elevated the L. albigena subspecies to full species level, but the elevation was not widely accepted.
