This species is known from three regions of New Britain, Papua New Guinea: the Whiteman, Range; the Nakanai Mountains; and the Baining Mountains (Kraus and Allison, 2007). It has been recorded from sea-level up to 865m asl.
Habitat and Ecology
It inhabits primary and advanced secondary rainforest, but has not been recorded from disturbed habitats. Animals are typically found while calling hidden in burrows under limestone rocks, crevices in such rocks, or under leaves, but they can also found wandering on the forest floor during the day (Kraus and Allison, 2007). Males call from within leaf-litter on the forest floor in lowland and foothill rainforest (Kraus and Allison, 2007). It is a species that breeds by direct development and lays its eggs on the ground.
It is abundant in suitable habitat.
It is believed to be threatened by the extensive logging currently taking place on New Britain, as the species does not adapt well to seriously modified habitats.
It is not known from any protected areas. Further research is needed to assess the population status, distribution and habitat requirements of this species.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on New Britain, Papua New Guinea.
