starts withAdult males measure 40–52 mm (1.6–2.0 in) and adult females 58–60 mm (2.3–2.4 in) in snout–vent length. The head is wider than it is long, almost semi-circular when viewed from above. The tympanum is visible as a depression in skin (hence the specific name concavitympanum, from Latin concavum for concave). The fingers have no webbing whereas the toes are basally webbed. The upper eyelids have large, irregular warts laterally, becoming less prominent medially. Symmetric crests of warts run from the behind the eyelids to the sacral area. Dorsal coloration is cryptic and resembles a dead leaf. The base color is pale yellow; the crests of warts are gray and bordered with gray lacework. The head has two gray mottled areas. The underside is pale pink, possibly with gray reticulations.
Tadpoles in Gosner stage 36 measure 50 mm (2.0 in) in snout–vent length.
