From the IUCN Red List Species Account:


Range Description

We restrict this species to southern Sumatra, Java and Bali (Indonesia). Specimens from outside this range are referred to in the accounts for H. raniceps and H. mocquardi (Sulawesi only). It is present below 1,571 m asl.

Habitat and Ecology

It is typically seen on rocks and vegetation along small lowland forest streams, but is also seen away from streams in forest, or in highland areas. Primary and degraded forests are equally favoured, but a reasonably closed canopy and gently flowing water are essential. Adults disperse widely in the forest and may even be found in wooded gardens. Breeding occurs at quiet side pools of forest streams or in temporary ponds at the edges of forests. On Sumatra it also breeds in ponds and in paddy fields. The maximum clutch size of H. chalconota is 2,207 eggs and it breeds year round (Premo 1985). Tadpoles live inside pools and quiet, deeper sections of streams (Grandison 1972, Dring 1979).


It is generally common in lowland forest streams, and is less common but still present in highland areas.

Population Trend


Major Threats

It has recently tested positive for Batrachochytrium dendrobatidis, although there are currently no reports of population declines for this species (Kusrini et al. 2008).

Conservation Actions

Provided existing protected areas and watershed forests remain reasonably intact, and that there isn't an epidemic event of chytridiomycosis, the species appears reasonably secure. It is important to assess the presence and extent of the impact of the chytrid fungus on frog populations in Indonesia (Kusrini et al. 2008).

Red List Status

Least Concern (LC)

Taxonomic Notes

We consider Hylarana raniceps to be a valid species following Dubois (1992). We restrict H. chalconota to Java, Bali and parts of southern Sumatra, Indonesia.
