From the IUCN Red List Species Account:


Range Description

This species is known widely through Sumatra and Java, Indonesia, up to 700 m asl, including Sipura and Simeulue islands in the Mentawai Islands. It is now also known from West and Central Provinces in Kalimantan, Indonesia (D. Iskandar pers. comm. May 2017). Recent records in Java have been provided for Magelang Regency in central Java (M. Kusrini pers. comm. May 2017), Gianyar Regency on Bali (Eprilurahman et al. 2016), and Sleman Regency, Bantul Regency and Kulon Progo Regency in D.I. Yogyakarta (Qurniawan and Eprilurahman 2012, Yudha et al. 2014).

Habitat and Ecology

This species lives in lowland moist forest, where it is associated with wetland habitat and always close to water. It can survive in secondary forest, rice plantations and human settlements providing that the moisture gradient is suitable. It breeds in puddles, ditches and slow-flowing streams.


It is a commonly found species, but not very abundant (Indonesia Red List Assessment Workshop May 2017). Surveys in 2017 in Gianyar Regency on Bali recorded several individuals of this species (R. Eprilurahman and D. Satria unpubl. data May 2017). Due to ongoing decline in the quality and extent of habitat, the population is suspected to be decreasing.

Population Trend


Major Threats

The main threat to this species is the loss of wetland habitat due to water abstraction from the development of human settlements (R. Eprilurahman and M. Kusrini pers. comm. May 2017).

Conservation Actions

This species occurs in a number of protected areas including Mount Gede Pagrango, Ujungkulon, Bukit Barisan Selatan and Kerinci Seblat National Parks, among others (Indonesia Red List Assessment Workshop May 2017).

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and presumed large population.

Taxonomic Notes

This species is part of the Occidozyga laevis complex (D. Iskandar pers. comm.).
