Leathery Milk Frog

Trachycephalus coriaceus
(Peters, 1867)
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.

My Flickr album for this species is here.
