This species is known from Bougainville Island in Papua New Guinea, and has also recently been recorded from Choiseul and Isabel Islands in the Solomon Islands (Richards pers. comm.). It has been found at 700-1,500m asl on Bougainville, and at 100-200m asl, possibly higher, on Choiseul and Isabel.
Habitat and Ecology
On Choiseul and Isabel, this species is active at night on the floor in tropical rainforest. On Bougainville, it lives on cliffs in steep mountains, and in cracks and fissures in the ground. It is a species that breeds by direct development, laying its eggs in fissures.
It is rare on Choiseul and Isabel, and very uncommon and hard to find on Bougainville.
Logging has possibly impacted some populations.
Its distribution on islands in the Solomon Islands archipelago needs to be documented, in addition to the impacts of logging needing to be assessed.
