Lophocebus

The genus Lophocebus refers to a group of nine species of slender, long-limbed monkeys found in African tropical forests, commonly known as mangabeys. These are quadrupedal monkeys with cheek pouches and deep depressions under their cheekbones. They communicate using a specialized vocal sac, and males can produce quite loud vocalizations.1

Mangabeys primarily feed on seeds, fruit, and leaves, using their large front teeth to bite into tough-coated fruits. Species within the genus Lophocebus tend to spend more time in trees than those in the genus Cercocebus. They have long, black fur, lack white eyelids, and carry their tails in a curved or question-mark shape. The term "lophi-" in zoology relates to a small crest or tuft.12
