I am going out on a limb and disagree, based on the fact that the tympanum is located about one eye diameter from the eye itself. In giants, the tympanum is about two eye diameters away from the eye. The local tribes in Mozambique believe that the dwarf frog is seen early in the season and grows into the giant later on as the season progresses and heavy rains appear. I guess they think they are the same species. Some herpetologists believe that the dwarf is just a subspecies of the giant. One important distinguishing feature is the male's call. I have recordings of both species and fairly easy to tell apart. To me, it really doesn't matter which species, they are awesome frogs
