Cercopithecoidea

Cercopithecoidea is a superfamily of primates that includes Old World monkeys. These monkeys, belonging to the family Cercopithecidae, are found across Africa and Asia. They are distinguished from New World monkeys by their narrow noses with downward-facing nostrils and the presence of sitting pads on their buttocks.12

Old World monkeys are diverse, with subfamilies like Cercopithecinae (which includes baboons and macaques) and Colobinae (which includes langurs). They are known for their intelligence and social behavior, often living in troops. While generally having tails, some species, like macaques, have very short tails. The term "cercopid" can also refer to a type of froghopper, an insect, which is a completely different organism.134
