This species has been recorded from widely scattered localities throughout Borneo, Sumatra, and possibly the Malay Peninsula. A population also occurs on Tioman Island. In general, there is considerable uncertainty about the identification, and consequently the range of this species (see taxonomic notes for this species and R. signata). It probably occurs more widely than current records suggest, especially in areas between known sites. It is found below 1,000m asl.
Habitat and Ecology
It occurs in primary and slightly disturbed rainforests. Breeding takes place in small streams and the tadpoles live in quiet side pools and in accumulations of dead leaves in open pools.
It appears to be abundant at most localities.
Deforestation is the principal threat to this species, resulting in the contraction and fragmentation of the habitat.
It is present in a number of protected areas across the region. Effective preservation of lowland rainforests is essential for this species.
The taxonomy of this species is confused. It was previously considered to be a synonym of Hylarana signata, and possible specimens of H. picturata from the Malay Peninsula are still referred to as H. signata. The taxonomy is currently under investigation (R. Brown pers. comm.).
