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.[2] According to the current understanding, this species is known with certainty only from Java (also the type locality), Madura, Bali, and Kangean Islands, Indonesia.[3] The species is also commonly reported to occur in the Philippines (Palawan, Mindoro, Bohol, Basilan, Mindanao islands),[4] but these are believed to refer to another, unnamed species.[1][3]
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.[5] This applies, for example, to Leptobrachium hainanense from Hainan[6] and Leptobrachium liui from the mainland China,[3] and Leptobrachium smithi from Thailand and Burma.[5][7]
Description and habitat
Leptobrachium hasseltii has a large head that is wider than the body and with large eyes with a scarlet coloured iris, tips of digits round and webbed at the base, and smooth skin. Adults are dark above, patterned with darker circles, with a white ventral surface with black blotches. Juveniles are bluish in color. Females are larger (70 mm (2.8 in) snout-vent length) than males (60 mm (2.4 in) SVL).[4]
Leptobrachium hasseltii inhabits the forest floor litter of montane and lowland rainforests. Tadpoles live in quiet pools and ponds. The species is threatened by deforestation.[1]
