Geographic Range [top]
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.).

Threats [top]
Major Threat(s): 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 [top]
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.
