This species is known from mainland Thailand, adjoining southern Lao People's Democratic Republic (Taylor 1962; Stuart 1999), and Dac Lac Province in southern Viet Nam (Orlov 2002). It presumably occurs more widely than current records suggest.
Habitat and Ecology
It is known mostly from areas originally covered with deciduous dipterocarp forest, and has not been reported from agricultural areas. Breeding takes place in seasonal pools (Heyer 1973).
There is no reliable information available on the population status of this species. Large numbers in markets could indicate large populations, or intensive collection, or both. It has not been found during some recent herpetofauna surveys of areas where it was historically known to occur (P. van Dijk pers. comm.), suggesting a possible decline.
The major threat to this species is intensive collection for local consumption, gravid females being preferred. Its habitat has also been extensively impacted by fire and other anthropogenic processes, or cleared completely for agricultural development and other land uses.
It is known to occur in or near a number of protected areas, but several of these are not secure from the threats of uncontrolled fires and collecting of frogs for human consumption. Efforts are needed to secure these national parks and wildlife sanctuaries, and to manage the exploitation of populations of this species outside protected areas.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because this species is in significant decline (but at a rate of less than 30% over ten years) because it is being over-harvested for food throughout its range, and is suffering from habitat loss, thus making the species close to qualifying for Vulnerable.
