Cacajao Ayresii, a new species of uakari monkey was found by Jean-Phillipe Boubli, New Zealand primatologist, in a mountainous region of the Amazon.

Jean-Phillipe Boubli of the University of Auckland found the animal after following native Yanomamo Indians on their hunts along the Rio Aracá, a tributary of the Rio Negro in Brazil.

"They told us about this black uakari monkey, which was slightly different to the one we knew from Pico de Neblina National Park, where I'd worked earlier," Boubli said.

"I searched for that monkey for at least five years. The reason I couldn't find it was because the place where they were was sort of unexpected."

Uakaris normally live in flooded river forests, but this one turned up in a mountainous region on the Brazil-Venezuela border, far from its nearest relatives.
