This species is known only from the type locality near Agaun, in Milne Bay Province, Papua New Guinea, at 1,200m asl.
Habitat and Ecology
The only known population was first observed around a pool in rainforest. Males were observed calling from low vegetation. These frogs lay eggs attached to leaves overhanging the water.
There is no information regarding its population status.
The type locality was subsequently cleared for gardens, but the population appears to have persisted despite the clearance. Gardening might eventually impact on this (and other) populations. However, if this species has a wide distribution (as is likely), then gardening is unlikely to have more than a localized impact and will be of little concern in the foreseeable future.
The distribution and population status of this species needs to be better documented to aid its conservation.
