A large conspicuously coloured frog. M 60-65 mm, F 90-95 mm. Dorsum yellowish in males, red-orange in females, often with many small reticulations. In both sexes often with a rhomboid dark marking. Ventrally uniform whitish. Skin smooth with two dorsolateral folds. Tympanum rather indisctinct, about 1/3 of eye diameter. Tibiotarsal articulation reaches the tympanum. Fingertips not enlarged. A large inner metatarsal tubercle. No webbing on hands, weakly expressed webbing on feet (Glaw and Vences 2007).

Similar species: Very similar to D. antongilii and only distinguishable by the relatively faint colour differences (Glaw and Vences 2007).
