A small brown treefrog. Males 25-30 mm, females larger (estimated size of one female 35 mm). Back brown often with more or less distinct transverse bars and numerous, very small, dispersed black spots. Flanks with numerous white spots, but without marks underneath tympanum or eye. Slightly developed white lateral folds along arm and tarsus. Skin on the back smooth. Venter creamish. Iris brown around the pupil, surrounded by red on the outer iris area. Iris periphery is blue. Nostrils are equidistant between the eye and tip of snout. Tympanum/eye ratio about 1/2. Tibiotarsal articulation reaches between nostril and tip of snout when hind limb is brought forward. Small dermal flaps or tubercles on the heel and elbow.
Webbing of the hand: a trace of webbing between 1 and 2i and 2e and 3i, 3e(1.5), 4(1); webbing of the foot 1(0.75), 2i(1), 2e(0.5), 3i(1.5), 3e(0.5), 4i/e(1.5), 5(0.5). Males with nuptial pads and a slightly distensible, single subgular vocal sac.
Specimens from Andringitra have a similar call but differ by a network of elevated ridges on the back, distinct black tubercles on the legs and a distinct white spot between eye and upper lip.
