Western chorus frogs are small , smooth skinned, and greenish-grey, reddish, olive, or brown in color. Differences in color can occur locally and should not be confused for range-specific populations. Typically, these frogs have three dark-brown or grey stripes which extend down the entire dorsal side. The dorsal stripes can be broken up, reduced, or even absent in certain specimens. The white or cream-colored underside or ventral side of the frog typically has dark, scattered flecks. A single white stripe runs along the upper lip, and a heavy dark stripe runs across the eye and along each side from the snout to the leg. A dark triangular spot on the head may also be seen in some individuals. These frogs have small, round toes without pads and very little webbing between each toe.
