Philautus ingeri is one of the larger species in the genus Philautus (36 mm in males; up to 50 mm snout-vent length in females). The sharp-edged nose, color pattern of the iris, and the dark band between eye and nose make this a clearly distinguishable frog. 

The species seems to be restricted to forests at higher levels of elevation, ranging from 1300 to 1500 m asl.

The call is a series of five notes. Reproduction most likely is via directly developing embryos.
