A species of fork-marked lemur believed to be new to science has been found in the forests of Madagascar.

The find is revealed on the BBC documentary Decade of Discovery.

Primate expert and president of Conservation International, Russ Mittermeier, first spotted the lemur during an expedition in 1995, but has confirmed its existence whilst filming the documentary this year, when he and his colleagues captured and took blood samples from the small primate before returning it to its forest home.

Decade of Discovery, a collaboration between Conservation International and the BBC's Natural History Unit, will be broadcast at 20.00BST on Tuesday 14 December on BBC Two.
