This species is known from the vicinity of the type locality, the Baliem River Valley, and from Wanena, in Papua, Indonesia, at around 1,600m asl. It is presumably more widespread but additional data are lacking.
Habitat and Ecology
It was recorded in grassland and rural gardens, and was observed breeding in permanent pools.
Its population status is unknown, but the first collection contained hundreds of specimens.
No threats to this species are known, but it appears able to withstand a degree of habitat modification.
Its distribution, habitat requirements, and population status need to be properly documented. It is not known from any protected areas.
