This species occurs in a relatively wide area of mountains in western Papua New Guinea, extending almost to the Papuan (Indonesia) border. It almost certainly also occurs in suitable habitats in Papua, Indonesia but as yet has not been recorded from there. It occurs from 600-1,600m asl.
Habitat and Ecology
It occurs along small streams in rainforest. Like other species in the genus, it is presumably a species that breeds by direct development.
It seems to be abundant where it occurs, and presumably has large populations throughout its known range and elsewhere in suitable, unexplored areas. It is probably stable and secure.
There are no known threats.
None required at present. It is not known from any protected areas.
