|Scientific classification Pelophylax|
They are also known as water frogs, as they spend much of the summer living in aquatic habitat; the pond frogs can be found more often, by comparison, on dry land, as long as there is sufficient humidity.
Systematics and taxonomy
Most authors throughout the 19th and 20th century disagreed with Fitzinger's assessment.
That genus, in the loose circumscription, eventually became a sort of "wastebin taxon".
Around 2000, with molecular phylogenetic studies becoming commonplace, it was discovered that Fitzinger's assessment was correct after all – not only is Pelophylax an independent genus, but it does in fact belong to a lineage of Raninae not particularly close to Rana.
But it also turned out that these Eurasian green frogs might not form a monophyletic lineage.
The sheer number of species involved in the group of Pelophylax and its closest relatives means that it will probably be some time until the definite circumscription of this genus is resolved.
The Pelophylax frogs belong to a group of moderately advanced Raninae – possibly a clade – that also includes such genera as Babina, Glandirana, Hylarana, Pulchrana, Sanguirana, Sylvirana, as well as Hydrophylax which like Pelophylax is suspected of being not monophyletic.
These genera were formerly also included in Rana by most authors, and several of them have only been established in the 1990s.
And as regards the possible paraphyly of Pelophylax, it seems that some species assigned there are very close to Hylarana, and thus it might simply be a matter of moving them to that genus.

In addition, one species has been described that is sometimes assigned to Pelophylax, but must be considered a nomen oblitum:
- "Hyla" ranaeformis Laurenti, 1768 (= "Hyla gibbosa" Lacépède, 1788 (unavailable: published in non-binomial work) )
