M 21-24 mm. Tympanum distinct, 3/5 of eye diameter. Tibiotarsal articulation reaches the tympanum. Toe 3 longer than toe 5. Skin smooth or slightly granular. Dorsally variable, brown with symmetrical dark and light markings. Ventrally uniform grey with a dark throat (Glaw and Vences 2007).
Similar species: A. boulengeri (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Species is located in Andohahela, Malahelo, Nahampoana, Tolagnaro (Glaw and Vences 2007). It ranges from sea level to 1500m asl (Nussbaum and Vallan 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Calls from tree trunks or rocks at perch heights of 1 m. Eggs and tadpoles in water-filled tree holes, guarded by the male (Glaw and Vences 2007).
Calls: A single short melodious note that is repeated after regular intervals. Note repetition rate 85/min (Glaw and Vences 2007).
Trends and Threats
Species is listed as data deficient because of continuing uncertainties as to its extent of occurrence, status and ecological requirements. Its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, fires and expanding human settlements. It occurs in the Rï¿½serve Spï¿½ciale dï¿½Ambohitantely, which is poorly managed, and Parc National d'Andohahela, which is well managed (Nussbaum and Vallan 2008).
Possible reasons for amphibian decline
General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Subtle changes to necessary specialized habitat
