Photos that I've seen of the Aurita do not show horns much larger than a Cranwelli. An adult Cornuta has very tall pointed projections. Aurita does have the largest stripe down its back. From eye to eye and about and down the back. Of course some of more unknown species may have even larger horns.

I've seen a few photos and videos. From what I've seen Cornuta seems to have the largest, but may differ from frog to frog.
