Identification

Adult

Species description based on Savage (2002). Males are much smaller than females. Males reach lengths of 45 mm, females, 74 mm.

Dorsal

Dorsal coloration varies from olive green to olive brown. Darker spots or blotches are usually present. The dorsal surface may be smooth or slightly bumpy. The upper surfaces of the arms and legs have dark bars.

Ventral

The ventral surface is smooth and yellow.

Concealed surfaces

Rear surfaces of thighs are dark brown, with many small light spots.

Eye

The upper half of the iris is golden, the lower half brown.

Ecology behavior and evolution

Ecology

This species is often found near smaller streams (Savage 2002). It jumps into the water to escape threats (Savage 2002).

Call

This species has no vocal sac and probably does not call (Savage 2002).
