M 22-26 mm, F 26-32 mm. Tibiotarsal articulation reaches at most the nostril. Fifth toe shorter than third toe. Femoral glands in males often small and not very prominent. Frenal stripe mostly rather distinct and well defined but usually fading before reaching the nostril. Ventrally often with a dark throat with a thin light median line (Glaw and Vences 2007).
Variation: As currently understood this species contains various cryptic species, among them a form from the Ranomafana area (Glaw and Vences 2007).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Ambatobe, Ambolokopatrika corridor, Ampokafo, Anjanaharibe, Besariaka, Fizoana, Foulpointe, Maroantsetra, Marojejy, Navana, Nosy Boraha, Nosy Mangabe, Rantabe, Sahafary, Voloina (Glaw and Vences 2007). It occurs from sea level up to 600 m asl, in pristine or slightly disturbed rainforest (Glaw and Vences 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: A locally very common species in low-altitude rainforests along the east coast. Males call during the day from dense vegetation along streams (Glaw and Vences 2007).
Calls: From Foulpointe. Slow series of 16-21 relatively long pulsed notes (Glaw and Vences 2007).
Trends and Threats
Abundant but decreasing. This species is found within several protected areas. Can tolerate slightly disturbed forest. The main threat is habitat loss due to subsistence agriculture, logging, charcoal manufacture, invasion and spread of eucalyptus, grazing and expanding human settlement (Glaw 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
