This frog was observed during the day in the forested area in Mantadia National Park (Perinet), in central-eastern Madagascar.
Not sure about this ID, but these medium to large sized Mantidactylus spp. were fairly common on the road leading to Ankaratra, in and near irrigation and rice paddies around a small village. It looks different than M. curtus on the massif.
Probably not really M. curtus but some yet to be described species
