This species is known only from Mount Dayman in Milne Bay Province, south-eastern Papua New Guinea, at 2,230m asl.
Habitat and Ecology
It occurs in tropical rainforest and breeds by direct development.
The original collection contained 78 specimens. There have been recent surveys of the species' known range but results of these surveys are not yet available (Allison pers. comm.). Apart from this, there is no recent information on this species' population status.
Part of the type series was collected in a patch of forest in grassland suggesting that habitat fragmentation might be a threat to this species. However, insufficient data are available at this stage to state this with certainty.
Its type locality is not within a protected area.
Red List Status
Data Deficient (DD)
