Mocking Bromeliad Treefrog
Also known as:
Mocking Treefrog, Quacking Bromeliad Treefrog
Santa Cruz Forest Reserve, Loreto, Peru—January 20, 2013
was described by Jungfer et al in this paper
in 2000. It's very similar to O. planiceps
overall. Dick Bartlett
told me that O. deridens
has a tympanum about half the size of the eye, whereas O. planiceps
has a larger tympanum, so I'm guessing that this one is O. deridens

Based on the smallish tympanum, overall small size, and radiating lines in the iris, I've tentatively identified this Osteocephalus
as O. deridens

Based on the radial pattern in the iris, the relatively small size, and the pattern, I believe this frog is a Osteocephalus deridens
. The etymology of this name comes from the original species description: "The specific name is the present participle of the Latin deridere
(make fun of someone) in allusion to the males' calls from the treetops that sound as if they are laughing at the collectors' vain attempts to reach them."

When I first saw this, my brain didn't quite register what it was; it looked like some sort of algae or lichens on an otherwise innocent frog. But it's just crazy coloration/patterning.
