This species is currently known only from Moran in the Kikori Integrated Conservation and Development Project (KICDP) Area in the Southern Highlands Province of Papua New Guinea (6°14.363'S, 143°07.660'E) at an altitude of 1,800m asl (Richards et al., 2007). This species was not detected at numerous sites at lower elevations in the KICDP area, and was also absent from higher sites on Mount Sisa (Richards et al., 2007). It is possible that this species is restricted to a relatively narrow altitudinal range within the KICDP.
Habitat and Ecology
This species is found in lower-montane rainforest on steep limestone in dangerous terrain that included deep hidden sink-holes (Richards et al., 2007). The frogs call from elevated positions between 0.2-0.5m above ground in dense mossy montane forest after heavy rain at night (Richards et al., 2007). No calling was heard on dry nights (Richards et al., 2007). Males called from within curled leaves in dense low foliage and are extremely difficult to detect (Richards et al., 2007). It presumably breeds by direct development without dependence on water.
Many individuals were heard calling at its only known site (Richards et al., 2007).
There is no information on threats to this species.
It is known only from a restricted area within the Kikori Integrated Conservation and Development Project Area. Surveys are needed to determine its geographic distribution, ecological requirements, threats and conservation needs.
