From the IUCN Red List Species Account:


Range Description

This species is currently known only from Yapen Island, in Papua Province, Indonesia. There are records from Amoman Mountain (1º 45' S, 136º19' E), at 1,130m asl, and from around 1 km south of here at 1,000m asl. on (Günther and Richards, 2006). It can be expected to occur more widely.

Habitat and Ecology

This apparently largely arboreal species has been recorded along a road traversing partly logged mossy rainforest (Günther and Richards, 2006). Animals have been found on trees 1-8m above the ground, with a single specimen found on the ground in a small earth hole at the margin of a road about 6m from the adjacent forest (Günther and Richards, 2006). The calling sites suggest that the species is more arboreal than terrestrial (Günther and Richards, 2006). Animals on trees were associated with accumulations of humus formed by decomposing wood or decomposing epiphytes and which were encrusted with moss (Günther and Richards, 2006). Reproduction in this species has not been recorded, but it presumably breeds by direct development.


It seems to occur at high densities, as over 100 males were heard calling along a 500m length of road, and sometimes the frogs were only a few metres apart.

Population Trend


Major Threats

At present there are no obvious threats to this species, but more information is needed (R. Günther pers. comm.)

Conservation Actions

There are no direct conservation measures in place for this species, and it is not known from any protected areas (R. Günther pers. comm.). 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.
