This species is known only from the vicinity of Wamangu, adjacent to the Nakam River in the Sepik Basin, East Sepik Province, Papua New Guinea, at 180m asl (Richards, 2007). It is likely to occur more widely.
Habitat and Ecology
It has been found in a complex patchwork of secondary lowland rainforest, patches of bamboo, coconut plantations, cleared forest and gardens, and sago swamps (Richards, 2007). The males call predominantly on relatively cool, wet nights, and are common around pools and swamps (particularly sago swamps) in severely disturbed habitats (Richards, 20070. Several males were found calling from sago palm leaves about 3–5m high in the evening after rain; others were found in lowland rainforest near the sago swamps, calling from between 50cm–2m above ground on leaves. The species preumably deposits its eggs on leaves above water, into which the larvae fall to complete their development.
It is apparently common in suitable habitat (Richards, 2007).
It appears to be an adaptable species, and so is unlikely to be facing any significant threats.
It is not known from any protected areas. Surveys are needed to determine the geographic range of this poorly known species.
Red List Status
Data Deficient (DD)
Listed as Data Deficient because it has only recently been discovered, and is currently only known from one site. However it is common and appears to be adaptable, so discovery of additional populations will probably allow its reassignment as Least Concern.
