suggested new characters of taxonomic importance in this genus. Therefore, during the examination of type material particular attention has been paid to the following characters: the chaetiger on which the first hooks arise, the number of hooks per parapodium and the number of anterior reduced parapodia. No obvious differences were observed (Table
