[2] This species was formerly included in the genus Oreophryne, but was in 2017 moved to Aphantophryne based on molecular data.

[2][3] The specific name parkeri honours Hampton Wildman Parker, an English zoologist and herpetologist.

The snout bluntly rounded, approaching truncate, in dorsal view, and vertical in profile.

The dorsum is light brown and has irregular darker small spots interrupted by a sharply defined, dark W-like mark in the scapular area.

In Sentani, males were calling from about 3–6 m above ground in banana plants and sago palms in an area of garden regrowth.
