Herpetofauna
As Herpetofauna the totality of all is amphibians - and reptile species referred to a region. The term goes back to the Greek ἕρπειν herpein “crawl, creep” and the derived ἕρπετον herpeton “reptile” - originally all cold- blooded terrestrial vertebrates , i.e. both reptiles and amphibians, were referred to with this term.
