This taxon ranges from northeastern India (West Bengal, Assam, Meghalaya, Nagaland, Manipur and Mizoram), possibly Bangladesh (its presence in this country requires confirmation) through Myanmar, Thailand, Cambodia, Lao People's Democratic Republic and much of Viet Nam to central and southern China (Shannxi, Sichuan, Yunnan, Guizhou, Zhejiang, Anhui, Jiangxi, Hunan, Fujian, Guangdong, Guangxi, Hainan and Hong Kong). The southern limit in Peninsular Thailand is uncertain [Smith (1930) noted specimens of O. chloronota (as O. livida) from Nakhon Si Thammarat and O. hosii from Chumphon, indicating a substantial overlap]. Taylor (1962) ignored any peninsular occurrence of O. chloronota (as O. livida). It ranges from 100-1,900 m asl.
Habitat and Ecology
It inhabits forested montane river. The rivers can vary from shallow and slow moving to torrential and deep. Animals can be found on boulders and logs, both in and around the water. It is presumed to breed in streams, but its breeding habits are unknown.
In South Asia this is regarded as a common frog with a stable population. In Southeast Asia it is not a rare frog but it is rarely common, never reaching the densities of O. hosii in comparable habitat.
It is threatened by deforestation, the pollution of waterways (often with agrochemicals), and hydrological changes. These frogs are harvested for food by some ethnic groups in Viet Nam and farmers in China (Yunnan and Hainan). Often, only the females are harvested, as these are thought to be 'adult' frogs (Bain et al. 2003).
Existing protected areas seem to secure viable populations throughout the range of the taxon, and their maintenance is of prime importance. Further taxonomic work is urgently needed, as this might be a species complex containing a number of highly threatened species. It is protected by national legislation in India.
We follow Bain et al. (2003) in recognizing that this is a wide ranging species previously erroneously referred to as Odorrana livida. O. livida is restricted to the neotype locality in the Dawna Mountains of southern Myanmar. Bain et al. (2003) provided a partial revision of the O. chloronota complex, and considered it likely that previously undescribed species in the O. chloronota complex will be found, both in the wild and in current museum collections.
