Brown woolly monkey

The brown woolly monkey, common woolly monkey, or Humboldt's woolly monkey (Lagothrix lagotricha) is a woolly monkey from Colombia, Ecuador, Peruand Brazil. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active.

Many published sources give the systematic name as L. lagothricha, because Fooden . chose that spelling as the correct spelling, when he revised the genus. Von Humboldt used both spellings in his original description, so the International Zoological Code permits a first reviser to choose which spelling is to be considered "correct".
