This species is currently known only from Phu Jong-Na Yoi National Park, in Na Chaloey District, Ubon Ratchatani Province, in eastern Thailand, at 230-360m asl (Stuart et al., 2006). Future surveys might show it to occur a little more widely, but a month-long survey in Laos, close to the type locality, did not locate any specimens (B.L. Stuart, pers. comm.). However, specimens from a new locality in Thailand, that are probably this species, are currently being examined (Y. Chuaynkern, pers. comm.).
Habitat and Ecology
This species has been found in a variety of habitats: on igneous bedrock in deciduous dipterocarp forest with a grassy understory; on a road through hilly evergreen forest; and in hilly evergreen forest near flowing, rocky streams (Stuart et al., 2006). Adults appear to be most active at night (19h00–21h00 ) (Stuart et al., 2006). Tadpoles have been found in a rain-filled depression on igneous bedrock in deciduous dipterocarp forest with grassy understory (Stuart et al., 2006). Although it has been found in slightly disturbed habitats (on a road in forest), there is no evidence that it can tolerate severe anthropogenic disturbance (B.L. Stuart pers. comm.).
This species is common in suitable habitat in Phu Jong-Na Yoi National Park.
No information is available on threats to this species. All records so far are from a well-managed national park.
It occurs in the Phu Jong-Na Yoi National Park (Stuart et al., 2006). Surveys are needed to determine its geographic distribution, abundance, ecological requirements, threats and conservation needs.
