A brownish line from the nostrils to the eye, the supratympanic fold is also brown. Ventral surface light. Skin smooth. Nostrils slightly nearer to tip of snout than to eye. Tympanum distinct, about 1/2 of eye size, smaller in specimens from Tolagnaro. Tibiotarsal articulation reaches the eye. Lateral metatarsalia connected. Webbing of the hand rudimentary; webbing of the foot 1(1), 2i(2), 2e(1), 3i(2.5), 3e(1), 4i/e(3), 5(1). Males with distinct, sometimes blackish, oblong femoral glands.

Life History, Abundance, Activity, and Special Behaviors
Habits: Lives in Pandanus leaf axils.

Call: Unknown.

Eggs and tadpoles (from the terra typica): Eggs unknown. Tadpoles live in water-filled leaf axils of Pandanus. They are mainly brownish, with the anterior part of the body appearing reddish. The body is extremely depressed, eyes are situated dorsally, and the mouth is small and directed downwards. At midlength of the tail, the caudal musculature represents about 1/2 of total tail height. Total length in stage 25: 19-25 mm; in stages 26-30: 27-40 mm. Metamorphosing young measure 12-14 mm and resemble the adults.

Trends and Threats
It occurs in Parc National de Marojejy and the Réserve Spéciale d’Anjanaharibe-Sud (Nussbaum et al. 2008).
