Botrytella parva (Chordariaceae, Phaeophyceae) is reported for the first time from the eastern Mediterranean Sea. The species was collected from the Dardanelles (Sea of Marmara, Turkey) in the sublittoral zone. Data concerning its habitat, morphology and worldwide distribution are presented. The justification for transfer of Polytretus reinboldii to Botrytella is discussed, and we found morphological arguments to resurrect the generic name Polytretus. A key to the species of Botrytella and Polytretus is provided.
