From the IUCN Red List Species Account:

 

Range Description

This species is known from a single locality in the Khao Chong Mountains of Peninsular Thailand. It presumably occurs more widely within these mountains, as has been mapped. The type locality is at an elevation of 300m asl. Some populations in Peninsular Thailand currently assigned to Ansonia malayana might in fact belong to this species (L. Grismer pers. comm.).

Habitat and Ecology

It is restricted to lowland primary tropical moist forest. It is a stream-breeding species.

Population

It is apparently uncommon. A pair was collected in 1979, and a further five individuals have been collected since (Kiew 1984b, Matsui, Nabhitabhata and Panha 1998).

Population Trend

Unknown

Major Threats

The habitat of this species appears to be reasonably well protected at present, and there are currently no major threats. However, given its restricted range, it is potentially at risk from stochastic events and pollution from adjacent tourist sites.

Conservation Actions

The known range is entirely within the Khao Chong Mountains protected area. The population status of this species requires careful monitoring, given that it is known only from a single location.
