From the IUCN Red List Species Account:


Range Description

This species is reported from much of Peninsular Malaysia, and Yala province to Chumphon, Thailand. It probably occurs more widely than current records suggest, especially in areas between known sites. It is also present on Phuket Island, Thailand. It is found at altitudes between 300 and 1,300m asl.

Habitat and Ecology

It is associated with lowland and montane tropical moist forests. Adults are often encountered in boulder crevices and leaf-litter in streams. Breeding takes place in these streams where the larvae also develop. It has been recorded in selectively logged forest after three years of regrowth.


It appears to be locally common in Peninsular Malaysia, but uncommon in Peninsular Thailand.

Population Trend

Major Threats

It is potentially threatened by clear-cutting of forest habitat. The resulting siltation of forest streams might threaten larval habitat.

Conservation Actions

The species occurs in a number of protected areas and reserved forests. It is protected by national legislation in Thailand. Further research in into the life history, taxonomy and population size of this species is needed.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and presumed large population.

Taxonomic Notes

This taxon is likely to be a complex of more than one species, and further comparisons of specimens from Peninsular Thailand and Peninsular Malaysia are required. The northernmost opulations of Peninsular Thailand are provisionally attributed to Ansonia malayana (see Inger, 1960), though they might in fact belong to A. siamensis (L. Grismer pers. comm.).
