Rio Mayo titi monkey

Rio Mayo titi monkey (Plecturocebus oenanthe) is a titi monkey in the genus Plecturocebus, family Pitheciidae, the New World monkeys that also include the other titis, the sakis and the uakaris. The Mammal Diversity Database credits the species name to (O. Thomas, 1924) and lists its country distribution as Peru. It is endemic to Peru. It was once thought to be confined to the Alto Mayo valley, but research showed that its range extends south to the Bajo Mayo and Huallaga Central. Once classed as vulnerable, it is now considered critically endangered because of major habitat loss, and it was included in the World's 25 Most Endangered Primates list in October 2012. Forests where it lives are cleared for agriculture. The Mammal Diversity Database gives its IUCN Red List status as Critically Endangered.
