Pyxicephalus Differences

Terry - Yes, I am volunteering!

Damn. So close with the illustration, but just missed the mark. Ok, now that you have explained the interorbital bar. (but isn't 'inter' - inside? so inside the eye?) It has always looked to me, that adspersus has a very individual iris. Is there a name for that type of adspersus eye?

Thanks for volunteering. Let's take John's advice and look through all the photos of Pyxicephalus that are posted on the form. We'll need to pick the best ones for the article. I was also baffled with interorbital. I remembered that the prefix "inter" means to cross over boundaries and "orbital" refered to the eye, so the light bulb in my brain went off and realized the bar is between the eyes, not within the eye area.

John .... I hoped that that was an adult edulis. After all the pictures I have been looking at, I really had hoped. Shoot!!! Now that you say that.... I think I understand. I can try again.

IMHO(with what little I know) adspersus is kind of unique, but edulis and obbianus should look similar? The physical descriptions only work on the adults, not the babies or juveniles? We really need to lock down pictures of the 'original' described species? But on all counts ..... count me in. I can work on more graphics as needed.

Great job anyway. You have the right idea, just wrong frog. The key descriptions work for adult frogs and non-hybrids. I understand that juvenile P. edulis also has the white spot in the tympanum. That might be the only way to tell the difference between juvenile species. The frog on the left looked like edulis to me, the spot on the tympanum is either round or crescent shape, according to Carruthers. But, John is the pyxie guru
