The newly discovered Pseudophilautus hypomelas were found in elevations of in lower montane rain forests, not far from the Adam's Peak in the Peak Wilderness. They were commonly observed in bushes close (<1 m) to the ground. The species seems to prefer grassy habitats without full canopy cover, such as those in disturbed areas. Günther's specimens were from a different location, from Nuwara Eliya District (to the extent that the location is known).
