Pristimantis malkini — Malkin’s Rain Frog
Some other names for this species:
Rio Ampiyacu Robber Frog
I had no good guess what frog this might be, but Dick Bartlett helpfully pointed out that it looks like Pristimantis malkini, and indeed it does look just like photos of that species that I found subsequently.
