This species is known from two sites in New Guinea: 5.5 km west of Tabubil township, in Western Province, Papua New Guinea (5°17’30”S and 141°11’55”E;) at 500m asl; and adjacent to the Tiri River, Mamberamo Drainage, in Papua Province, Indonesia (3°17’30”S, 138°34’53”) at 80m asl (Dennis and Cunningham, 2006). It is expected to occur more widely, especially in suitable habitat in intervening areas (Dennis and Cunningham, 2006).
Habitat and Ecology
This species is likely to be a canopy dweller and may glide given its extensively webbed fingers and toes (Dennis and Cunningham, 2006). It has been found in lowland rainforest in areas of very high rainfall (Dennis and Cunningham, 2006). It is presumed to breed by larval development, and may lay eggs in swamps or ponds on the forest floor, and/or in small canopy ponds (those trapped in tree forks and hollows and regularly replenished by high rainfall) (Dennis and Cunningham, 2006).
There is no information on its abundance. Only two specimens have ever been found, but it might be a canopy species which is hard to detect.
There is no information on threats to this species.
There are no direct conservation measures in place for this species, and it is not known from any protected areas. Further studies are needed into the distribution, abundance, threats and general ecology of the species.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
