Ansonia is a genus of true toads found in south India, northern Thailand, Malay Peninsula, Tioman Island, Borneo, and Mindanao (Philippines).[1] These small forest species spawn in streams and have torrent-adapted tadpoles.[2] Common name stream toads has been coined for the genus, although individual species are also being referred to as slender toads.[1]

The genus was named by Stoliczka after the governor of Penang, Colonel Edward Anson.[3]
