[1][3] The specific name parkeri honors Fred Parker,[2] Australian naturalist and explorer[4] who collected the type series.

[2] Cornufer parkeri bukanensis has much less warty skin, relatively larger eyes, and relatively broader head than the nominotypical subspecies.

[2] Cornufer parkeri occurs in uplifted coral landscapes at elevations below 100 m (330 ft).

It is a terrestrial frog that can be found in lowland rainforest, regrowth forest, rural gardens, villages, and other anthropogenic habitats.

Cornufer parkeri is an adaptable species, but its range is very small, making it vulnerable to chance events.
