No tympanum is externally visible. The supratympanic fold is evident and extends from the back of the eye to the shoulder. Digital tips are not expanded and webbing is absent. Skin is mostly smooth but becomes slightly granular along flanks and in the vicinity of the head; the eyelids have small tubercles. The dorsum is uniformly red brown and has irregular white spots, primarily along the flanks and the dorsal surfaces of thighs. The belly is also uniformly red brown and has irregular white spots. There are light stripes at tip of fingers and toes when viewed from above. Some specimens are lighter (especially juveniles) and have a light bar between the eyelids. Males have conspicuous, rounded, and flattened inguinal gland.
