This species is known from scattered localities through Thailand, eastern Myanmar, northern Lao People's Democratic Republic and southern China (Smith, 1930; Taylor, 1962; Yang, 1991; Zhang and Wen, 2000; Stuart et al., 2006). Through most of this area it is known from very few records. In southern China it is so far known from southern Yunnan, Guangxi, Gaungdong and Hainan provinces. It probably occurs more widely than current records suggest, especially in areas between known sites, for example in northern viet Nam. It is found at about 500-760m asl.
Habitat and Ecology
It is a poorly known species that has been recorded from monsoon evergreen forest and rainforest, usually on the forest floor in the vicinity of fast-flowing streams, creeks and rivers. It probably breeds in streams.
It is generally an uncommon species, and is only occasionally encountered through most of its range.
It is apparently restricted to closed-canopy evergreen forest, and is probably threatened by logging, agricultural encroachment, expanding human settlements and fire.
The range of the species includes several protected areas. Safeguarding the ecological integrity of its forest habitat, particularly with regard to fire containment within protected areas, should be a priority. Research is needed to determine the geographic distribution, ecological requirements, threats and conservation needs of this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
We follow Ohler (2007) in treating Hylarana nigrotympanica (Dubois, 1992) as a synonym of this species.
