proposes new genus names for some species of amphibians. According to it, the green toad, previously named Bufo viridis, should now be called Pseudepidalea viridis (Laurenti, 1768). Though, some authors do not agree with this conclusion, and suggest to keep the 'old' name (see
Vences M. 2007 - The Amphibian Tree of Life: Ideologie, Chaos oder biologische Realität? Zeitschrift für Feldherpetologie, 14 (2): 153-162 for example).

The green toad is a rare and threatened species in continental France. It is found in only three departments:
Moselle, Bas-Rhin and Haut-Rhin. A recent paper sumarizes the status of the species in Alsace:

Issue 14 of the monography Mertensiella, published by the German herpetological society (DGHT), deals exusively with the green toad:
