It is endemic to Papua New Guinea and only known from the vicinity of its type locality on the western slope of Mount Obree, Central Province.

A pair of angular dermal ridges runs in the scapular region.

The dorsum is tan, light yellow-brown, or pink brown stippled with black.

[1] The type series was collected from lower montane rainforest at 1,640–1,840 m (5,380–6,040 ft) above sea level.

The species was relatively common, but difficult to collect because of its cryptic habits; a few animals were active on the forest floor at night.
