Dusky Pygmy Sheep Frog (Syncope antenori)
This was the tiniest of all the many, many frogs I saw in Peru. It was perhaps a quarter of an inch long. I originally thought it was a teeny tiny baby Syncope bassleri, but reading up on the other small sheep frogs led me into thinking that it's probably Syncope antenori instead.

Here is a complete list of the herps I saw in the wild on my 2014 MT Amazon Expeditions trip.
