Two often indistinct and longitudinal interocular tubercles. Colouration very variable. Males with blackish paired subgular vocal sacs (Glaw and Vences 2007).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Madagascar

Manongarivo, Montagne d’Ambre (Glaw and Vences 2007). This species has been observed at an elevational range between 500-1200 m asl in pristine rainforest only (Raxworthy and Vences 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night from bushes, 0.5-1.5 m above the ground, in or near rainforest, usually close to streams. Generalized free swimming tadpoles in small streams (Glaw and Vences 2007).

Calls: A slow series of about 15 unharmonious notes (Glaw and Vences 2007).

Trends and Threats
This species is listed as vulnerable because its Extent of Occurrence is less than 20,000 km², its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in northern Madagascar. It has a very fragmented distribution but occurs within several protected areas: the Parc National de Montagne d'Ambre, the Réserve Naturelle Intégrale du Tsaratanana, and the Réserve Spéciale de Manongarivo. A major threat is habitat loss, due to expanding subsistence agriculture, logging, charcoal manufacture, increased grazing, invasion and spread of eucalyptus, and expanding human settlement (Raxworthy 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
Habitat fragmentation
