Scientists have identified five new species of the elusive Amazonian saki monkeys in South American forests.
For many years, it was believed that there were just five species of sakis, but this study showed the existence of 16 — five of them new to science.The five new species are found in Brazil, Peru, and Bolivia — three of them are endemic to Brazil and one to Peru. Three species recognised were previously considered to be subspecies, and another three, already described, were previously thought to be just variants.
The study is the largest revision for any Neotropical primate genus in more than half a century, researchers said.Dr laura K Marsh, the director and co-founder of the Global Conservation Institute, carried out the study — 10 years of research involving the examination of specimens in 36 museums in 17 countries in North America, South America, Europe and Japan.“I began to suspect there might be more species of saki monkeys when I was doing field research in Ecuador,” Marsh said. “The more I saw, the more I realised that scientists had been confused in their evaluation of the diversity of sakis for over two centuries,” said Marsh.
