This species is known only from several locations on Halmahera and Morotai Islands, in the Maluku Islands, Indonesia. Its elevational range is not known, but the highest point within its range is 1,200m asl.
Habitat and Ecology
There is no reliable information available, but it probably occurs in streams in tropical rainforest. As with other species in the genus, it presumably lays large eggs in torrential, clear and rocky streams and the tadpoles have large suckers.
The species was last collected on Halmahera Island in 1989.
The major threat to this species is habitat loss, following the widespread logging that has taken place on Halmahera Island in the past few years.
There are no protected areas within its range. Improved habitat protection is required at sites at which this species is known to occur. There is also a need for further survey work to determine the current population status of this species.
Red List Status
Listed as Vulnerable as its Extent of Occurrence is less than 20,000km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat due to extensive logging on Halmahera and Morotai, Indonesia.
