This species is known from a few localities in northeastern Thailand (Matsui and Panha, 2006). There are records from: Phu Sri Tan Wildlife Sanctuary, in Kalasin Province, at 500m asl (Matsui and Panha, 2006); Phu Pha Namtip Non-hunting Area, in Roi Et Province (Matsui and Panha, 2006); and Phu Jong-Na Yoi National Park, in Na Chaloey District, Ubon Ratchatani Province, at 230-325m asl (Stuart et al., 2006). It can be expected to occur more widely, in particular in areas between the currently known locations.
Habitat and Ecology
This species has been found in a variety of habitats: on the ground or in low vegetation near a rain-filled depression in igneous bedrock in deciduous dipterocarp forest with grassy understory; on the ground next to a seep running over solid rock substrate at the side of a road through deciduous dipterocarp forest; on vegetation 0.5–1.8m above a small, rocky stream and a small pond near a road through hilly evergreen forest; in a dried rocky streambed with small pools; and on the leaves of trees (<2m above the ground) along the bank of a small pond (Matsui and Panha, 2006; Stuart et al., 2006). Tadpoles have been found in a small stream pool with silt and leaf litter substrate in hilly evergreen forest (Stuart et al., 2006).
There is no information on the abundance of this species.
The species has so far only been found in protected areas (Matsui and Panha, 2006; Stuart et al., 2006), and so it is possible that there are no major threats to this species at these locations. However, it might be found in future at other sites that are less secure. The species is found on the "Thai-Lao Dry Plateau" (Inger, 1999), where much of the natural vegetation has been removed (Matsui and Panha, 2006) for agriculture and collecting of wood, and so the species has probably lost much of its original habitat.
It has been recorded from Phu Sri Tan Wildlife Sanctuary, Phu Pha Namtip Non-hunting Area, and Phu Jong-Na Yoi National Park. Surveys are needed to determine its geographic distribution, abundance, ecological requirements, threats and conservation needs.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
