Washington, Aug 11 - Over 350 new species, including the world's smallest deer, a 'flying frog' and a 100 million-year-old gecko, have been discovered in the Eastern Himalayas, according to a World Wildlife Fund (WWF) report.

A decade of research carried out by scientists in remote mountain areas endangered by rising global temperatures brought exciting discoveries such as a bright green frog that uses its red and long webbed feet to glide in the air.

One of the most significant findings was not exactly 'new' in the classic sense. A 100-million year-old gecko, the oldest fossil gecko species known to science, was discovered in an amber mine in the Hukawng Valley in northern Myanmar.

The report 'The Eastern Himalayas - Where Worlds Collide' details discoveries made by scientists from various organisations between 1998 and 2008 in a region reaching across Bhutan and northeast India to the far north of Myanmar as well as Nepal and southern parts of Tibet.

The report describes more than 350 new species that have been discovered - including 244 plants, 16 amphibians, 16 reptiles, 14 fish, 2 birds, 2 mammals and at least 60 new invertebrates.
