Range Description This species is known from the vicinity of the type locality at 1,500-1,700m asl in the central Nakanai Mountains, West New Britain Province, Papua New Guinea. It is presumed to occur in suitable habitat above 1,200m asl throughout this mountain range, and might possibly also occur in the Whiteman and Baining Mountains.
Habitat and Ecology It occurs in primary rainforest characterized by epiphyte-covered Nothofagus stands with a relatively open canopy and dense climbing bamboo thickets covering tree fall gaps. At higher altitudes, this species is found in forest with a thick (5-10cm deep) humus and leaf-litter layer, and lots of decaying branches and fallen logs, all covered with thick moss. It is able to climb and prefers perches less than 1m above the ground. It is most often found on shoots and leaves in bamboo thickets in treefall gaps, indicating at least some tolerance to habitat degradation.There is no standing surface water in the known habitat of this species, and it is presumed to breed by direct development.
Population Within its range, it appears to be very common, although it is difficult to locate.
Population Trend unknown
Major Threats The most likely threats to it are habitat loss coupled with the effects of invasive species, particularly chytrid fungus and other pathogens. Habitat loss, and opening of the habitat to invasive species, are most likely to occur if high altitudes in the Nakanai Mountains are opened up to logging.
Conservation Actions This species does not occur in any protected areas.
Red List Status Data Deficient (DD)
Rationale Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements.
