Allochrocebus is an African primate genus from the group of vervet monkeys (Cercopithecidae) with three species.

features

Allochrocebus species are relatively large, long-legged monkeys with head-to-trunk lengths of 45 to 68 cm, tail lengths of 46 to 80 cm and a weight of 3 to 10 kg. Females always stay smaller and only reach about 60% of the weight of the males, which also differ from the females by their particularly strong canine teeth. There is hardly any gender dimorphism in terms of coat color. Allochrocebus species are predominantly dark in color with black, gray and rust-red fur and a white to light gray beard. The skull is similar to that of the actual monkeys ( Cercopithecus ), the postcranial skeleton (the area of the skeleton following the skull) shows some differences to the skeleton of this genus. The joints of the arms and legs are more stable in adaptation to a more terrestrial life, but also less mobile than those of the real monkeys.

Way of life

Two of the three Allochrocebus species live in mountain forests, the other in lowland rainforest. They form small groups of two to twelve animals. These consist of a full-grown male and one or more females and their young. The food consists to a large extent (more than 78% in the eastern monkey) low-growing plants and must therefore be looked for on the ground. The predators of the Allochrocebus species include the leopard and the African golden cat .

species

Currently (as of February 2015) three species are included in the genus Allochrocebus :

The eastern full-bearded monkey ( Allochrocebus lhoesti ), which is found in mountain forests in the eastern part of the Democratic Republic of the Congo, Uganda , Rwanda and Burundi .
The western full-bearded or Prussian monkey ( Allochrocebus preussi ), which lives in southwestern Cameroon near the Cameroon Mountains , the Bamenda highlands , the Nigerian Obudu plateau , and on the island of Bioko .
The sun-tailed monkey ( allochrocebus solatus ), the distribution area of the lowland forest between Ogooué and Ngounié is limited in Gabon.

Systematics

Allochrocebus was established in 1912 by the American zoologist Daniel Giraud Elliot as a subgenus of the real monkeys ( Cercopithecus ). In later work on the vervet monkey system, no sub-genus was used, but the three species were combined as the lhoesti group within the genus Cercopithecus . Phylogenetic studies show, however, that they are more closely related to the green monkeys ( Chlorocebus ) and the hussar monkey ( Erythrocebus patas ) than to the monkeys of the genus Cercopithecus . In more recent systematics, Allochrocebus is therefore used as a generic name for the three species.
