It is found in Sarawak and Sabah, northern Borneo (Malaysia), and presumably also in Kalimantan on the Indonesian part of the island.

[3] Its natural habitats are lowland rainforests at elevations of 150–750 m (490–2,460 ft) asl.

Adults range widely over the floor and herb stratum in areas of steep terrain, but breeding requires small, clear, rocky-bottomed streams.

[1] Males call at night, sitting in low vegetation close to streams.

It is threatened by habitat loss (deforestation and the associated siltation of streams; plantations).
