Hypsiboas geographicus? | Hypsiboas boans (Hylidae)
« on: Thu, 16 March 2017, 07:46:10 PM »
I found these frogs at night time on a rock in the river near Fred Panza's Zintete camp near Fredberg, February '17.

They were large frogs, like 8 to 10 cm or maybe even bigger.

I thought they were Hypsiboas geograhicus, but then I met Paul Ouboter at Brownsberg camp and he said they were probably something else. I did not get the chance to show him the pictures, unfortunately.

Smiles,
Klaas

Hello Klaas, and welcome at GNF! :)

I'm not sure if I'll be able to help you, but I do have two questions:
1) are these three photos of three different frogs?
2) do you have photos with a higher resolution? They don't need to be larger, but a bit less blurry would surely help with IDing them.

Cheers, Auke

Hi Auke,

Thanks for the welcome! I appreciate you running this site/forum! I have some more questions, but need time to send them in...

I have better pictures, taken by a participant in my group, Annemiek. She kindly provided me with her pictures and I have attached them. These are two different animals.

I hope this helps!
Kind regards,
Klaas

Hi Klaas,

Nice to read you like this forum! I'm not (yet?) an expert in frogology myself, but I've asked a reknown herpetologist to see if he can give some good IDs. To prevent confusion, I'd like to suggest you post different specimens as different posts, unless there is some need to compare them to eachother.

Cheers,

Auke

Hi Auke,

Thanx, but I have reason to believe that these are two animals of the same species. I mean, they were like very close to eachother on a rock in the river. I'd say that is a very good reason to compare them with eachother?

I will kepp it in mind for future posts.

Kind regards,
Klaas

So you think all photos you've posted in this thread belong to the same species? Or would the first specimen (the blurry photos) be something different?

If you think all three belong to the same species, yes, they can stay in this same thread.

Cheers, Auke

That is correct, Auke, all frogs were in the same spot at the same time. In general they look very much alike. I received another photo, which I post herewith. I hope someone will recognize this species. I was amazed by the eye of this animal!

Hi klaas!

This is a Hypsiboas boans, they look very much alike the geographicus. The Geographicus however, has whiteish spots on the elbows, this is the easiest way to keep them apart.

Greetings,
Dick

I agree that all these photos are of Hypsiboas boans. H. geographicus is much smaller than H. boans.
