This species is endemic to Java, Indonesia. From current knowledge it occurs only in west and central Java from 50-1,200m asl.
Habitat and Ecology
It is restricted to unpolluted, clear, fast-flowing streams and torrents, in forests and in somewhat more open areas. Breeding takes place in streams.
It is a common species in its specialized habitat.
Soil erosion and the sedimentation of streams, as well as agro-chemical pollution, are the main threats to this species. These threats, which result from habitat modification taking place around streams, are leading to a rapid loss of suitable habitats within its range.
It is found in Halimun National Park, Ujong Kulon National Park, Gunung Gede Pangrango National Park, and Dieng Nature Reserve.
