Leptodactylus petersii — Peter’s Jungle Frog
The smaller Leptodactylus frogs can be tricky to tell apart, and I'm not certain about this one. I'm calling it Leptodactylus petersii because nothing seems to rule that ID out, and it bears a very strong resemblance to the photo of L. petersii in the Bartletts's book.
Both of these little Leptodactylus frogs seem likely to be young L. petersii, though they might be some other closely related and similar-looking species such as L. leptodactyloides.
