Short-snouted Swampfrog (Dendropsophus brevifrons)
This small treefrog came out at night on the plants right along the edge of the Madre Selva camp clearing. They look a lot like a slightly more interesting version of Dendropsophus leali.

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

The most easily seen distinctive mark on this species is the pair of white marks between the eye and the upper lip. Other closely related species have only a single white mark, or no white marks.

Short-snouted Swampfrog (Dendropsophus brevifrons)
A couple of things can be said about the Short-snouted Swampfrog: they have very short snouts, and they are often found in swamps. Now you know.

This is not the only Dendropsophus species in the area to have a short snout and two light marks on the upper lip. As far as I know, there is one other: Dendropsophus bokermanni. However, D. bokermanni should be nearly patternless at night, thus clearly ruling out the first and third ones here. The middle one is iffier, but it does have a noticeable pattern, assuming the scattered spots count.
