REMARKS: Until recently the only species of Terebellides reported for the Mediterranean Sea was T. stroemii. However, recent research in the NA (Parapar et al. 2013) revealed two more species to be present, T. gracilis (Malm, 1874) and a newly described species T. mediterranea Parapar, Mikac & Fiege, 2013. All former records of T. stroemii in the Adriatic need to be reviewed as some of them may belong to other species of Terebellides. Parapar & Hutchings (2014) described a neotype of T. stroemii from Norway; they performed a comparative study of the morphological characteristics of T. stroemii from several recent descriptions in the north-east Atlantic (including the one from the Adriatic Sea by Parapar et al. 2013) and observed slight differences among them, suggesting that several cryptic species are present. These species are difficult to be identified using only a traditional morphological study of external characters, thus molecular methodologies will have to be performed.
