Ambilobe, Ankarafantsika (Ampijoroa, Antsiloky, Lac Tsimaloto), Berara forest, Lokobe, Manongarivo, Nosy Be. It occurs from sea level to 1,600m asl in slow-flowing streams of rainforest, heavily degraded areas, and open swampy areas. It also inhabits agricultural land (Nussbaum and Vences 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Found along streams and in swamps. Males call from hidden positions during the day and often from more open sites on the stream border or in the stream at night. Eggs are deposited in the leaf litter or on rocks next to the water, tadpoles are flushed into the stream after hatching and develop there.

Calls: A series of 4-5 pulsed notes of low intensity.

Breeding takes place in slow-flowing streams (Nussbaum and Vences 2008).

Trends and Threats
It occurs in many protected areas (Nussbaum and Vences 2008).
