This species is endemic to the mountains of western Sumatra, from Aceh Province to Lampung Province (Kurniati 2008). It occurs from 1,500 m asl to above 1,200 m asl (Kurniati 2008).
Habitat and Ecology
It lives in clean torrents and fast-flowing streams in forest and open areas near the forest. It breeds in streams.
It is abundant in suitable habitat, however the species appears to be declining at some sites due to increasing threats of agriculture and pollution. For example, the species was present at Gunung Tujuh, Jambi Province in 2005 (Kurniati 2008), but was not found at that same site during surveys in June 2011 probably because agricultural land became more extensive in the area (Kurniati 2012).
The major threat is siltation of the streams and chemical pollution resulting from deforestation and agriculture (paddy fields).
It occurs in several protected areas, including Gunung Leuser, Kerinci-Seblat, Batang Gadis and Barisan-Selatan National Parks.
Further research on this species' taxonomy, distribution, population size and trends is needed.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution and presumed large population.
