Andohahela, Andohariana, Chaines Anosyennes, Andringitra (Cuvette Boby, Imaitso forest), Ivohibe, Maharira summit (Ranomafana). It occurs between 1,350-2,500m asl along rocky outcrops in forested zones and above tree line (Cadle and Raxworthy 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: A species restricted to high elevations, occurring among large boulders or in small caves above the tree-line or in rainforest above 1200 m elevation. At Andringitra, subadults can be found hidden under rocks at high elevations above the tree line. Males call from within caves and cavities during day and night. Very large blackish tadpoles develop in streams.

Calls: A very soft and inconspicuous sound for such a relatively large frog, reminding the dripping of water.

Breeding takes place in streams. It takes at least a year for the tadpoles to begin metamorphosis (Cadle and Raxworthy 2008).

Trends and Threats
Vulnerable: extent of occurrence is less than 20,000 km2 and its area of occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat. It occurs in Parc National de Ranomafana, Parc National d'Andringitra, Parc National d'Andohahela, and probably Parc National de Midongy du Sud (Cadle and Raxworthy 2008).

Possible reasons for amphibian decline

Intensified agriculture or grazing
