This does not look like a comfortable leaf upon which to perch. But I guess Amazonian frogs are tough.

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

The seemingly ungrammatical "striped-throated" phrase refers to a broad median white stripe on the throat, which is vaguely visible in the second photo here.

The lanthanites epithet is Greek for "hidden one", which refers to the idea of John D. Lynch (the biologist who described this species) that these frogs were actually just one variation of Pristimantis conspicillatus. But then he did his field work and concluded that they were in fact a different species.
