This species from New Guinea is currently known only from the eastern slope of the Wondiwoi Mountains at the base of the Wandammen Peninsula (Cenderawasih Bay), in Papua Province, Indonesia, at 350-850m asl (Günther, 2006). It can be expected to occur more widely.
Habitat and Ecology
It is found in a primary rainforest at altitudes above 350m asl, and animals prefer slopes with exposed stones and small rocks (Günther, 2006). Some specimens were found a few metres away from rocks on leaf litter covering humus or clay soil (Günther, 2006). Nearly all calling males maintained a position at a crevice or an overhanging rock or stone (Günther, 2006). This is direct developing species in which the males exhibit parental care by guarding the terrestrial eggs and transporting the hatched froglets on their backs (Günther, 2006). It can probably tolerate a certain level of habitat disturbance, but is unlikely to be able to survive in opened-up habitats (R. Günther pers. comm.).
It is a common species with more than 100 calling males counted during a walk of 4 km (Günther, 2006).
There are no obvious threats to this species at present, but more information is needed (R. Günther pers. comm.).
It occurs in the protected area on the Wandammen Peninsula (R. Günther pers. comm.). Additional studies are needed into the distribution, abundance, breeding biology, threats and general ecology of this species.
