[Tofuman]

That's a great description Thanks allot.

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?

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.

The frog on the right is adspersus.

Terry and everyone - I encourage you to search the forum for photos posted over the past 2 years and pick the ones that best illustrate what you're trying to show. Then post the links and I can work it all into an article and credit everyone involved as authors. What do you think?

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.

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

Well this is the thing - I don't claim to be a guru on Pyxies, just that I know when something is not a Pyxicephalus adspersus. After that, I probably know less than you Terry. Do you think the one on the left is Pyxicephalus edulis?

John, this is edulis?

What a beautiful photo.

Terrry, it is "interocular" bar. According to Channing.

You're right, Jeff

Carruthers and du Preez calls it "interorbital". I hope it's just a matter of semantics.

WOW did I miss a lot over the weekend. I agree with John that the frog pictured looks different from an edulis. In my opinion it looks physically like a hybrid between the two. Or more of an inter-grade. Something like whats happened between the 3 budgett's frog species. Edit- So the frog in the comparison is obbianus? That would make sence.

Jeff the last picture you posted is an edulis. I know it was directed to john(sorry) but I'm sure he would agree.

Nice diagrams by the way.

I have lots of pictures of chubbz I would be happy to donate to you all I'll send them to Jeff tonight. His younger pictures are very good quality(it was before my good camera broke).
I'm very excited about this project we're starting. I'm happy we're taking action to try and get to the bottom of this as a forum.

If there's anything else you all need let me know. I have a few pyxie pictures I've "collected off the internet from places. I had hundreds of different pyxies pictures on my old computer..but it broke. lol

The frog in Jeff's picture is more like what I know as edulis. Terry, do you have any of Carruthers or Passmore's books to hand? I know the book they wrote together in the late 90s has both species pictured extensively.
