Gephyromantis zavona (Vences, Andreone, Glaw & Randrianirina 2003)

M 35-41 mm, F 41-44 mm. Very similar to G. granulatus but slightly smaller, with a shorter snout, and less distinct femoral glands. Most specimens without a continuous light stripe along the upper lip (Glaw and Vences 2007).Taken with permission from Glaw and Vences (2007).

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).

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).

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).
