On the basis of morphological and molecular studies, we identified the Australian endemic green alga known as  Caulerpa distichophylla  along the coasts of Sicily (Italy, Mediterranean Sea). The slender  Caulerpa  previously reported as  C. taxifolia  from southeastern Turkey (Gulf of Iskenderun) also belongs to  C. distichophylla . Morphologically,  C. distichophylla  clearly differs from  C. taxifolia  in its slender thallus and the lack of large rhizoidal pillars. However, genetic data do not provide undisputed evidence that the species are distinct. Sequences of the  tuf A cpDNA gene and of the cp 16S rDNA intron-2 sequences separated the two taxa by only one single nucleotide mutation, whereas ITS rDNA sequences did not clearly distinguish them. The new combination  Caulerpa taxifolia  var.  distichophylla  is therefore proposed. Western and eastern Mediterranean populations of  C. taxifolia  var.  distichophylla  are probably the result of introduction events from southwestern Australia. Although the vector of primary introductions remains unknown (aquarium trade or shipping), maritime traffic appears to be the most likely vector of secondary dispersal.  C. taxifolia  var.  distichophylla  is closely related to  C. taxifolia , hence interbreeding with the other  C. taxifolia  strains in the Mediterranean Sea might be expected to occur.
