Newly discovered primate 'already facing extinction'

The Popa langur, named after its home on Mount Popa, is critically endangered with numbers down to about 200 individuals.

Langurs are a group of leaf-eating monkeys that are found across south east Asia.

The newly described animal is known for its distinctive spectacle-like eye patches and greyish-coloured fur. It is at risk from habitat loss and hunting.

Scientists have long suspected there might be a new species in Myanmar, based on DNA extracted from the droppings of wild monkeys, but evidence has been hard to find.
