M 27-30 mm, F 25-34 mm. A relatively small species with a very short snout and extended foot webbing: 1(0.25), 2i(0.75), 2e(0), 3i(1), 3e(0.25), 4i(1.5), 4e(1.25), 5(0). Distinguished by its partly paired subarticular tubercles from M. pauliani. Both M. madecassus and M. pauliani have a particular iris colour with a central darker part and an increasing number of small golden spots towards the edges.
Similar species: All other species of Brygoomantis are more or less similar, but the lack of vomerine teeth in M. madecassus is diagnostic.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Madagascar
Andringitra (Cuvette Boby and other sites). It occurs between 1,500-2,500m asl in rocky streams in forest or above the tree line and in rocky landscapes (Vences and Glaw 2008).
Life History, Abundance, Activity, and Special Behaviors
Habits: Exclusively in high-altitude streams above the tree line in the Andringitra massif.
Breeding takes place in slow-moving streams (Vences and Glaw 2008).
