Taxonomy
It was
L'Hoest's monkey is currently classified as a member of the genus Allochrocebus.[4][5] Formerly, L'Hoest's monkey included the taxon preussi from the Gulf of Guinea region as a subspecies,[6] but it is now considered a separate species, Preuss's monkey (A. preussi).
L'Hoest's monkey was formerly included in the genus
Physical characteristics
C. lhoesti has a short, dark brown coat, with a chestnut color across the back and a dark belly. Its cheeks are light gray with a pale moustache. It has a characteristic and prominent white bib,[9] In body length it is 12.5 to 27 inches (32 to 69 cm), with a 19-to-39-inch (48 to 99 cm) tail.[10] The male weighs about 6 kilograms (13 lb), while the smaller female weighs 3.5 kilograms (7.7 lb). Its tail is long and hook-shaped at the end.[11] They are born fully coated and with their eyes open.[10]
Habitat and distribution
L'Hoest's monkey occurs in northeastern
Behavior
C. lhoesti lives in fairly small groups dominated by females and have only a single male. The females are usually related, while the male stays only a couple of weeks or at most a couple of years. The adult male will make very loud and distinct calls.[11] They are active during the day, mostly during early morning and late afternoon. They sleep in trees in a sitting position, usually either holding branches or each other. When they are alarmed or see they are being observed, they will flee and take shelter in trees, and after become very still.[10][14] They are mostly terrestrial.[6]
Reproduction
L'Hoest's monkey breeds seasonally, with the timing depending on the area. After about a five-month gestation period, a single young will be born. The mother gives birth typically at night and where ever she happens to be at the time. Birth usually occurs at the end of the dry season, which allows lactation when rainfall is highest.[10] She will eat the placenta and lick the baby clean while it hangs on to her belly. The other females in the group will show much interest in the newborn and will try to hold it. After a few months, nursing becomes less frequent, but will continue for about two years when there is another birth. When male offspring reach sexual maturity, they will leave the group.[11] In captivity, they have been known to live for more than 30 years.[15]
Diet
In the wild, L'Hoest's monkey is primarily a herbivore, which will mostly eat fruit, mushrooms, herbs,[16] roots, and leaves. However, it will also occasionally eat eggs, lizards, and small birds.[10]
