Pelophylax cerigensis (Beerli, Hotz, Tunner, Heppich & Uzzell, 1994)

Pelophylax cerigensis is part of the western Palearctic water frog group, which is differentiated from the Palearctic brown frog group by its extensive foot webbing, males’ external lateral vocal sacs, mottling on inner thighs, and absence of a black face mask. In contrast to the calls of Pelophylax cretensis, the calls of Pelophylax cerigensis do not have amplitude subdivision beyond pulse groups (Beerli et al. 1994).
Dorsally, Pelophylax cerigensis is light brown or olive, and may have brown spots. There is no vertebral stripe, and the venter is creamy with mottled gray. The males have gray vocal sacs (Beerli et al. 1994).

The Crete water frogs diverged from other western Palearctic frogs anywhere from five to six million years ago. Karpathos frogs diverged from Anatolian frogs around three million years ago. These dates were obtained through genetic protein electrophoresis data. Pelophylax cerigensis is sister to Pelophylax bedriagae in both genetic (allelic differences at only 2 of 31 loci) and geographic distance (Beerli et al. 1994).
The species epithet “cerigensis” comes from Cerigo, which is a Latin name for Karpathos. Pelophylax cerigensis is the only water frog on Karpathos (Beerli et al. 1994).
Pelophylax cerigensis was previously named Rana cerigensis (Beerli et al. 1994).
