Webless Pygmy Tree Frog

The webless pygmy tree frog, Pseudophilautus hypomelas, is endemic to Sri Lanka. Albert Gunther described it in 1876 from 14 syntypes collected by Colonel Richard Henry Beddome and W. Ferguson, and there was no later record for more than 130 years. In April 2010 researchers found about 40 frogs in the Peak Wilderness Sanctuary, and study of them and the syntypes confirmed the species, which was redescribed in 2013 (Wikipedia, general species account).

It is a relatively small frog of 17 to 22 mm from snout to vent, with males smaller than females. The 2012 National Red List gives it as Extinct (Sri Lanka National Red List 2012), which predates the full confirmation of the rediscovery.
