This species is known only from Seima Biodiversity Conservation Area and Phnom Nam Lyr Wildlife Sanctuary at 500-700m asl in O'Rang District, Mondolkiri Province, eastern Cambodia (Stuart et al., 2006), and from 300 km to the north on Ngoc Linh Mountain, at 930-1,480m asl in Tra My District, Quang Nam Province, Vietnam (Bain and Truong, 2006). It is presumably, therefore, found through the the intervening area in the Truong Son and Annamite ranges.
Habitat and Ecology
It lives in hilly evergreen forest, and in mixed evergreen and deciduous forest with bamboo forest (Stuart et al., 2006). It is closely associated with streams, and is nocturnal, and can be found on leaf litter on the forest floor near streams (Stuart et al., 2006). It presumably breeds in streams by larval development. In Viet Nam it has only been found in primary or mature secondary forests, and it has not been recorded from degraded habitats (Nguyen Quang Truong, pers. comm.).
This species is locally abundant at its Cambodian site (B. Stuart, pers. comm.), but appears to be rare in its Vietnamese site, where only a few animals have been found (Nguyen Quang Truong, pers. comm.).
There is no direct information on threats, but it is believed to be affected by ongoing forest loss due to logging and expanding agriculture.
It occurs in the Seima Biodiversity Conservation Area and Phnom Nam Lyr Wildlife Sanctuary (Stuart et al., 2006). Surveys are needed to determine its geographic distribution, abundance, ecological requirements, threats and conservation needs.
