First record of the land planarian Caenoplana bicolor (Graff, 1899) (Platyhelminthes, Tricladida, Continenticola) in Greece.
New alien species are added every year to the European fauna. Although there are a few indigenous terrestrial flatworms in Europe, only one species has been recorded so far in Greece. For the first time, an alien flatworm species, Caenoplana bicolor, is recorded on the island of Crete. This finding suggests the need for control measures to prevent impacts from this bioinvasion.
