Aotus nigriceps (black-headed night monkey) is native to neotropical South America. Black-headed night monkeys are found in an area roughly within the boundaries of 5 to 15° south latitude and 75 to 55° west longitude. This area includes the Amazonian and Madeiran forests in Peru, Brazil, and Columbia and several forest areas found in the Huallaga, Ucayali, Yavari, Purus, and Madre de Dios river basins. It encompasses those areas south of the Amazon River to the Madeira River Basin and the northwestern part of the Tapajoz River Basin. Black-headed night monkeys are a species of "red-necked" or "southern" night monkeys.
