Let me start by saying a big THANK YOU to Dick Lock, who was kind enough to help me on a few frogs I posted earlier!

I have some more mystery herpetofauna...

This frog was at Cola Creek camp in February '17.

I would be grateful for an ID.

Kind regards,
Klaas

Hi Klaas,

No probs with the frogs! It is a nice pauze between the studying :P

This frog could be one of two. The Leptodactylus rhodomystax or L. mystaceus. For me, the easiest way to tell them apart is the belly. The mystaceus had creme or yellow belly, where the rhodomystax has a pale white belly.

I don't know if you have photo's from that?

Gr.
Dick

Thanx, Dick, yes I have one photo with some more belly on it. I wonder if this is enough to determine the species!

Kind regards,

This seems to be Leptodfactylus mystaceus, although the back has a very strange colour (greenish-grey), whereas all mystaceus I have seen are brown to reddish on the back. The best way to separatye L. mystaceus and L. rhiodomystax id looking at the back of the thighs. In L. rhodomystax there are numerous light blue points on a dark background. In L. mystaceus there are no such light blçue points.

The last picture posted on March 27, 2017 seems to be of a different species than L. mystaceus. Look at the upper lip, which is immaculte white in L. mystaceus, but in this specimen has black spots near the tip of the snout. This seems to be a Leptodactylus longirosris. Marinus Hoogmoed

Hi,
Could the 2 first pictures be Leptodactylus guianensis instead?
I agree the the last one seems to be a L. longirostris
