Santa Cruz field station, Depto Loreto, Peru. January 21, 2013.
I’ve only managed to see one of these frogs in six trips to Peru. The diagnostics for this species include a smooth, unicolored skin on head and dorsum, along with a pronounced dorsolateral fold that partially obscures the tympanum. It does not have the prominent small glands on the dorsum like other species of Trachycephalus – they are greatly reduced in size.
