M 32-36 mm, F 35-44 mm. Tympanum indistinct but typically visible. Tibiotarsal articulation reaches at the most between insertion of forelimb and tympanum. Tips of fingers and toes strongly enlarged. Skin relatively smooth with a number of large granules. Typically there are two symmetrical pairs of larger tubercles, a pair of elongated tubercles in the shoulder region and one of smaller tubercles on the posterior back. Dorsally green with symmetrical darker markings. Ventral pattern often with contrasted dark-white marbling, the dark colour extending onto the posterior belly (Glaw and Vences 2007).
Similar species: Morphologically closest to S. menabensis which, however, is distributed in western Madagascar. S. spinosa is larger and has tubercles of more spiny appearance, especially above forelimb insertion. S. boribory is much larger, lacks the two pairs of symmetrical tubercles on the dorsum and often has reddish colour on the terminal discs of fingers and toes (Glaw and Vences 2007).
