This species occurs only on Mount Pangrango, Mount Gedeh and Curug Luhur, Jawa Barat, Java, Indonesia, at altitudes between 1,000m and 2,000m asl.
Habitat and Ecology
It lives in the boundary zone between moist lowland and montane forest. It breeds in very slow-moving, intermittent streams in forest where the larvae also develop.
In 1976, this species was abundant within its small range. In 1987, it was very rare following the eruption of Mount Galunggung. There were no records from the early 1990s until 2003, when one individual was sighted from the Cibeureum Waterfall. It appears to have undergone a major decline.
It appears to have declined drastically due to a volcanic eruption. However, its decline is also reminiscent of similar disappearances of montane stream-breeding amphibians in other parts of the moist tropics, and so chytridiomycosis cannot be ruled out (although this disease has not so far been recorded in this region).
This species occurs in the Gunung Gede Pangrango National Park. Surveys are needed to locate this species and a captive-breeding programme might need to be established.
