Populations referred to this species are found on the Vogelkop Peninsula in Papua, Indonesia, and in the Star Mountains of Papua New Guinea. It occurs up to about 1,000m asl.
Habitat and Ecology
This species inhabits small rainforest streams in the foothills. It probably breeds in rocky streams and lays unpigmented eggs, like other species of the genus.
The populations in the Star Mountains are considered to be locally abundant.
Some streams within its range have been degraded by domestic pollution, potentially constituting a threat to it.
Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring. The taxonomy of different populations also needs to be assessed.
It is possible that the reports from Indonesia refer to undescribed species (Richards and Iskandar pers. comm.).
