This species is known only from Manus and Los Negros Islands, Manus Province, Papua New Guinea. It is widespread on both islands. It is found from 5 up to at least 296m asl, and is generally a lowland species (S. Richards, pers. comm.).
Habitat and Ecology
This species occurs in lowland rainforest, but also in degraded habitats and rural gardens. Males called from exposed or semi-exposed positions in forest litter, or from the base of grass tussocks in disturbed garden habitats, after heavy rain (Richards et al. 2007). This species seems to be at least as abundant in gardens where canopy cover is severely reduced, as it is in closed-canopy forest. This species occurred in micro-sympatry with P. latro, and calling males of the two species were frequently spaced less than 50 cm apart. It presumably breeds by direct development without dependence on water.
It is an abundant species.
It is an adaptable species that is not facing any significant threats.
It is not known from any protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
