Sun-tailed monkey

The sun-tailed monkey, Allochrocebus solatus, is a guenon from Gabon and one of the least studied primates within its habitat. It was found to be a new species in 1988 and was first placed in the genus Cercopithecus before being moved to Allochrocebus, where chromosomal analysis ties it closely to A. preussi and A. lhoesti. The animal prefers shady places with dense vegetation, and its numbers can stay steady even after light logging. Little is recorded about its diet, though it is known to favor fruit. Social groups consist of one male with several females, and observers have noted unusually low aggression toward related group members. Gabon has protected it by law since 1994, and about a tenth of its habitat lies inside Lope National Park.
