Yellow-tailed woolly monkey

The yellow-tailed woolly monkey (Oreonax flavicauda) is a New World monkey endemic to Peru. It is a rare primate species found only in the Peruvian Andes, in the departments of Amazonas and San Martin, as well as bordering areas of La Libertad, Huánuco and Loreto. The yellow-tailed woolly monkey was at first under the Lagothrix genera along with other woolly monkeys, but due to debatable primary sources, they have been placed under the Oreonax genera. Oreonax has been proposed to be a subgenus of Lagothrix but others have acknowledged it to be a full genus. A recent extensive study proves that the yellow-tailed woolly monkey may indeed be in the Lagothrix genera.
