Résumé :	Two colour polymorphic spittlebug species, Philaenus spumarius and Philaenus signatus were recorded for the first time in Gökçeada, Turkey. Three non-melanic – POP (populi), TYP (typicus), and VIT (vittata) – and three melanic MAR – (marginellus), FLA (flavicollis), and LCE (leucocephalus) – colour/pattern phenotypes of P. signatus were found. Philaenus spumarius was represented only by POP and TYP, which are expressed by a single pigmentation allele. The other six alleles were absent on this island, although they are found in most populations throughout the world. Stochastic events such as random genetic drift may be the reason for shaping the polymorphism of these two sympatric species in Gökçeada. Thus, the absence of pigmentation alleles possibly indicates the founder effect.
