This species is known from Bengkulu, West Sumatra, Jambi, South Sumatra, and Aceh Provinces in Sumatra, Indonesia. It occurs from 1,200–1,600 m asl. It probably occurs more widely than current records suggest.
Habitat and Ecology
This species occurs in marshland and submontane forest (Kurniati 2008, 2009). It presumably breeds in water, probably in streams.
It seems to be uncommon (D. Iskandar pers. comm. May 2017). During 2005 surveys in the vicinity of Kerinici Seblat National Park, the species was found to be common at Rawa Bento (i.e., at least 30 sightings/day in suitable habitat), but not common (i.e., 5-10 sightings/day on most survey days) at Gunung Tujuh (Kurniati 2008, 2009). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The main threat is localized forest loss due to agricultural development (including for non-timber plantations). Many activities by local people are negatively impacting its habitat at Rawa Bento, including modification of the the marshland for paddy fields (Kurniati 2009).
It occurs in Barisan-Selatan, Kerinci-Seblat and Gunung Leuser National Parks.
Recommended conservation actions include protection Rawa Bento as part of Kerinci-Seblat and engagement with local communities to manage and preserve the marshland (Kurniati 2009).
Further research on this species' taxonomy, distribution, population size and trends is recommended.
Red List Status
