Distribution and habitat

This frog is known from several widely separated locations in Malaysia. These include the Batu Caves, the Taman Negara National Park, and the Sekayu waterfalls in Trengganu-Berry. It is also found in Sumatra, Nias, Java, Madura and Bali. Its distribution within Indonesia is fragmented. Its habitat is among grasses in marshy land at altitudes of up to and in forests and forest fringes. It breeds in slow-flowing streams and stagnant water.

Status

This frog has a wide range and although the population seems to be declining, the IUCN rates it as being of "Least Concern" as it considers that the rate of decline is insufficient to justify listing it in a more threatened category. It is common in some parts of its range but is inconspicuous because of its small size and no particular threats to this species have been identified apart from some degradation of its forest habitat.
