Painted Antnest Frog (Lithodytes lineatus)
Youngsters of this ant-eating specialist look very similar to some of the poison frog species such as Ameerega hahneli. But full-grown adults like this one are easy to recognize; they are significantly larger than the poison frogs in this area, and they are somewhat rounder and less angular.

Here is a complete list of the herps I saw in the wild on my 2013 MT Amazon Expeditions trip.

Painted Antnest Frog (Lithodytes lineatus)
This was a particularly gigantic adult, nearly three inches long. It didn't really look like a poison frog at all. Maybe one of these years I'll actually get a photo of a youngster to illustrate the claim that they look like poison frogs.
