In adult males the SVL measures 60.5-64.2 mm, and the adult female holotype was measured to be 58.6 mm SVL. The snout is rounded in dorsal view, and obtuse in profile view. Nostrils are directed laterally. The loreal region is concave. A weak supratympanic fold runs above the tympanum and continues posterior to the tympanum. Fingers are extensively webbed, with relative lengths I< II< IV< III. Finger discs are broadly expanded with rounded covers. In breeding males, the prepollex bears small nuptial excrescences. Toe discs are broadly expanded, only slightly smaller than those of fingers. Skin is smooth to weakly granular dorsally, while ventral surfaces are coarsely areolate, except for the granular skin surrounding the vent. Pupil is vertically elliptical. Males have paired vocal slits and a single subgular vocal sac (McCranie and Wilson 2002).

Dorsal surfaces range from dark to light green (Lee 1996). Flanks, inner surfaces of the appendages, and the webbing between the first three fingers and first four toes are orange (Lee 1996). Ventral surfaces are light yellow or white (Lee 1996). The iris is dark red to deep purple (McCranie and Wilson 2002). The palpebral membrane has gold reticulations (Duellman 1970).

Tadpoles have a robust body that is deeper than it is broad. The tail is about twice the length of the body and is acuminate. Tail musculature is well developed. The spiracle is ventrolateral and sinistral. The vent tube opens to the right of the caudal fin. Papillae border the mouth parts, except on the dorsal surface of the upper lip. There are two upper and three lower rows of denticles. Tadpoles are purplish brown in coloration (Lee 1996).

The specific name moreletii is derived from Pierre-Marie Arthur Morelet, who was the collector of the syntypes (McCranie and Wilson 2002).
