It is endemic to New Guinea and found between Lorentz River in the west and Fly River in the east, thus being present in both West Papua (Indonesia) and Papua New Guinea.

[2] Common name Digul River fanged frog has been coined for it, in reference to Digul River where the type series was collected[2] in 1904 or 1905.

Colouration is brown above, with some patterning: a few darker markings on the back and legs, and some mottling in the upper lip.

The ventral surfaces are mottled with dark and light brown.

[3] There is little specific information about ecology of this species, but its natural habitat is presumably lowland rainforest where it lives on the forest floor, probably at elevations of no more than 500 m (1,600 ft).
