My herp count did not include amphibians or reptiles that I wasn’t completely certain on their identification (or at least, fairly certain), like this Leptodactylid (rain frog). It’s certainly a different species from those that were included in the count, but I can’t provide a definite identification, and therefore I cannot enter it in my herp database.
The perch this frog is using in a small leaf’s petiole, just to give some scale.
It appears that the name of the Neotropical Rattlesnake was updated from Crotalus durissus to simus.
A tiny, common Leptodactylid, Physalaemus pustulosus (the Pustuled thin-toed frog) could easily be mistaken for a toad (Bufonidae) because of its warty skin. It lacks obvious paratid glands, but the adult is so small (probably a maximum of 4-g) that it’s difficult to identify. The first ones I saw had fallen in a bucket-trap during the day and had dried out, so I mistakenly identified them as toadlets.
The males are easily identified by their blotchy, dark chin.
