terribilis vs bicolor

Observing both species there are definately size differences when comparing adults. The terribilis morphs (yellow, orange, and mint ) are larger than yellow and orange bicolors. THe coloration seems to be differant especially when comparing the belly or underside of the frogs. The terribilis are solid colored while the bicolor have black ventrums. I cannot hear any difference in calls, we keep them all side by side and adibly they are all the same to my ears.

We do have a "gold terribilis" that is questionable. THis frog was imported as terribilis. These frogs are larger than bicolors but smaller than terribilis, yet they have solid undersides like terribilis. We have sent some frogs for DNA testing and are awaiting the results, so hopefully this will shed some light on the species.
