Plural of guenon; multiple African monkeys of the genus Cercopithecus.
Regular English plural formation with -s from guenon. The singular guenon was borrowed from French, so the plural simply adds English -s rather than French -s.
Guenons are so diverse that researchers initially classified them as dozens of separate species—only recently did DNA analysis show that many were actually color variations of single species living at different altitudes.
