A monkey with eerie white circles around its eyes and a bright orange snake that feeds on slugs are among 224 new species identified by the World Wildlife Fund (WWF) in its latest review of the Greater Mekong region of Asia.
The primate has been named the Popa langur because it makes its home on the slopes of the extinct Mount Popa volcano in Myanmar and is the only mammal included on the revised list, which otherwise contains dozens of newly identified reptiles, frogs, newts and fish plus 155 varieties of plant species.
