In my opinion the Ceratoprhys joazeirensis is similar C.aurita to but smaller. I am South American and I've seen before me.The most important feature of the horns above the eye, very pronounced in this species.
Look at the difference between Aquaplayer picture, and the kattivo.
Aquaplay frog, it seems more a C.stolzmanni.
Maybe I'm wrong but it is my opinion.
