This species is known from the entire mountain ridge along the western side of Sumatra, in Indonesia. It was rediscovered in the late 1990s and has now been recorded widely. Known specimens belonging to this species may actually belong to another species, therefore further taxonomic research is needed (D. Iskandar pers. comm. May 2017). It occurs above 700 m asl and the extent of occurrence (EOO) of the current known range is 67,868 km2.
Habitat and Ecology
It lives in primary submontane and montane rainforest along streams. It occurs also in slightly disturbed forest habitats and agroforestry areas (D. Iskandar pers. comm. May 2017). The tadpoles have ventral suckers and stick on rocks in fast-moving streams, similar to Amolops (D. Iskandar and A. Hamidy pers. comm. May 2017).
It is a common species, especially around 1,000 m asl, but due to ongoing decline in the quality and extent of its habitat the population is suspected to be decreasing.
The major threat is the loss of its montane forest habitat due to agriculture, though forest loss is less serious at higher altitudes in Sumatra.
Its occurs within Kerinci Seblat, Gunung Leuser and Barisan-Selatan National Parks (D. Iskandar pers. comm. May 2017).
Studies on its distribution, population status, and threats are needed. Further taxonomic research is ongoing to resolve the taxonomy of this species.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population and degree of tolerance to habitat disturbance.
Further taxonomic work is needed because it is suspected that it is a synonym of another species and because its life history strategy is closer to Amolops (D. Iskandar pers. comm. May 2017).
