From the IUCN Red List Species Account:


Range Description

This species occurs in Peninsula Malaysia, Singapore, Indonesia (Sumatra, Natuna Besar and Pulau Bintan), and Borneo. It probably occurs more widely than current records suggest, especially in areas between known sites.

Habitat and Ecology

Swamp forests are the primary habitat for this toad. It is known to breed in standing water. It has been recorded from rubber plantations, presumably close to primary forest (Dring, 1979, Chan-ard et al., 1999).


There are no estimates of the size of subpopulations in Borneo, but it appears to be common but not abundant in intact swamp forests. It is uncommon in Sumatra and Singapore (Lim and Lim, 1992), and presumably localized or uncommon in Peninsular Malaysia.

Population Trend


Major Threats

The species' habitat is being rapidly reduced due to the expansion of oil palm plantations, infrastructure development and logging.

Conservation Actions

Preservation of some areas of swamp forest is needed to save the Bornean subpopulations. In mainland Southeast Asia population status information is needed. It is recorded from the Sungai Dusun Game Reserve in Peninsular Malaysia.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

Records of Ingerophrynus biporcatus from mainland Southeast Asia probably refer to Ingerophrynus quadriporcatus, and are treated as such here.
