M 17-22 mm, F 18-21 mm. Tympanum distinct, 1/2 of eye diameter. Tibiotarsal articulation reaches the tympanum. Toe 3 longer than toe 5. Skin smooth or slightly granular. Colour extremely variable, usually without green. Dorsally brownish, uniform or with symmetrical light and dark markings. Ventrally greyish to brown (Glaw and Vences 2007).

Similar species: Especially A. moramora and A. nigrigularis (Glaw and Vences 2007).

Variation: This species occurs over a large area of Madagascar�s east coast and may consist of several species. Populations from Masoala are genetically differentiated and are currently being described as a distinct species (Glaw and Vences 2007).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Madagascar

Species is located in Ambohimanga Atsimo, Andasibe, Ankeniheny, Fenoarivo, Italaviana, Ivoloina, Mahavelona, Manombo, Maroantsetra, Nosy Boraha, Ranomafana, Tampolo (Fenoarivo). Specimens from Masoala and Nosy Mangabe probably belong to a different species (Glaw and Vences 2007). It has been recorded from sea level up to 1300m asl (Vences and Glaw 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night from tree trunks at 1-2 m perch height. Eggs in water-filled tree holes or Ravenala leaf axils, guarded by the male. Common in low-altitude rainforest as well as in secondary or degraded vegetation (Glaw and Vences 2007).

Calls: A single short melodious note that is repeated after regular intervals. Note repetition rate 140-175/min (Glaw and Vences 2007).

Trends and Threats
Species is listed as least concern because of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category (Vences and Glaw 2008). Though it occurs in many protected areas, its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, and invasive spread of eucalyptus, livestock grazing and expanding human settlements (Vences and Glaw (2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
