Description

Adult males measure and adult females, based on a single specimen, in snout–vent length. The head is broader than it is long. The snout is short and rounded in dorsal view, truncate in profile. The eyes are large and protuberant. The tympanum is concealed beneath skin, but the tympanic annulus is visible below skin. The supratympanic fold is faint but concealing the tympanic annulus dorsally. The fingers and toes are partially webbed and bear large discs (smaller on the toes than on the fingers). Skin is smooth. Coloration is variable. Most specimens have clear dorsolateral bands, but some have a reticulated dorsal pattern. The background color is dark brown to brown, and the bands, spots, and reticulations are white to bright yellow.
