Its not that I havent heard of them but I more address frogs by scientific name as so many 'made up names' for frogs these days. Doing what I do for a living Nomenclature is my fav, but back to the frog in Madagascar I know 2 frogs of top of my head 'Mantella aurantiaca' and 'Dyscophus antongilii' so here we have 2 frogs that are commonly referred to red frogs and from same area hence why its always best practice to use the proper name.
