Open encyclopedia reference
Leptobrachium hasseltii (Hasselt's toad, Java spadefoot toad, Hasselt's litter frog, Tschudi's frog) is a species of toad found in Southeast Asia. This frog named after Dutch Naturalist Johan Conrad van Hasselt. According to the current understanding, this species is known with certainty only from Java (also the type locality), Madura, Bali, and Kangean Islands, Indonesia. The species is also commonly reported to occur in the Philippines (Palawan, Mindoro, Bohol, Basilan, Mindanao islands), but these are believed to refer to another, unnamed species.
As Leptobrachium hasseltii is the type species of genus Leptobrachium, populations from many areas were first referred to as conforming with this species, only to be later recognized as separate species. This applies, for example, to Leptobrachium hainanense from Hainan and Leptobrachium liui from the mainland China, and Leptobrachium smithi from Thailand and Burma.
