It is endemic to Papua New Guinea and only known from its type locality, Mount Michael in the Eastern Highlands Province.

The tympanum is visible but not prominent, and it is partially hidden by a weak supratympanic fold.

The body is dorsally slightly rugose and ventrally granular.

[2] The type series was collected from montane rainforest and alpine grassland on a cloud-swept ridge of Mount Michael at an elevation of 3,100 m (10,200 ft) above sea level.

The forests at higher elevations of Mount Michael experience pressure from the high human population density in the adjacent lowlands, constituting a threat.
