This species, endemic to Indonesia, is found in the southern part of Sumatra, Java, Madura, Bali, Lombok and it has been introduced to Sulawesi. Its occurrence in mainland Southeast Asia is uncertain. Records from Peninsular Malaysia (Berry, 1975) probably refer to Bufo quadriporcatus or Bufo parvus. It is a low altitude species, occurring up to 700m asl.
Habitat and Ecology
It occurs in lowland forest, degraded forest, and tree plantations, but can also be found around towns in Bali and Lombok. The introduced animals on Sulawesi occur near towns. It breeds in slow-flowing streams where the larvae also develop.
It is abundant in forested regions, but much less so in secondary and degraded habitats. It is common on Lombok but it is decreasing on Bali following the introduction of Bufo melanostictus. It is spreading on Sulawesi.
The main threat to this species is habitat loss. Populations outside forested areas might be decreasing where Bufo melanostictus has been introduced. On Java the species is decreasing generally.
It occurs in several protected areas in Java and Sumatra.
Records of this species from mainland Southeast Asia are probably Ingerophrynus quadriporcatus.
