Pampas Giant Glass Frog (Centrolene gemmatum)  

This species was described in the year 1985.  

The Pampas Giant Glass Frog inhabited a quite small area near San Francisco de Las Pampas in the Cotopaxi Province of Ecuador. The frog was found near streams in the cloud forest, it is assumed that the females attached their eggs to vegetation hanging over water, and that the tadpoles, while hatchings, dropped into the water where they continued to develop.  

There have been intensive search operations near the type locality, but, since not even a single individual was ever found, the species may very well be extinct now.
