Tsaratanana (Antsahamanara campsite), Manongarivo (Glaw and Vences 2007), at elevations between 800 to 1000 m (Andreone and Vences 2008). Found in pristine rainforest along rainforest streams (Glaw and Vences 2007).

Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night from the vegetation along rainforest streams. So far not found in secondary vegetation (Glaw and Vences 2007).

Calls: Series of 2-6 rapidly repeated unharmonious notes (Glaw and Vences 2007).

Trends and Threats
Listed as data deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements. Locally abundant. Found in two protected areas: the Réserve Naturelle Intégrale du Tsaratanana and the Réserve Spéciale de Manongarivo. Known only from pristine forest. Habitat is receding due to subsistence agriculture, logging, charcoal manufacture, invasion and spread of eucalyptus, grazing and expanding human settlement (Andreone and Vences 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
Subtle changes to necessary specialized habitat
