title: First record of Streptosyllis nunezi Faulwetter et al., 2008 (Annelida, Syllidae) from the United Kingdom, and amendment to the genus Streptosyllis Webster & Benedict, 1884.
abstract: During a benthic survey of a Marine Conservation Zone located on the Skerries Bank in the English Channel off the south-west coast of England, three specimens of Streptosyllis nunezi Faulwetter et al., 2008 were found. This is the second ever record of the species after its original description, and the first record from waters around the U.K. and a significant northerly range extension for a species previously only recorded from the Canary Islands and the Mediterranean Sea. A single simple ventral chaeta in each of the two posterior-most segments was discovered in this and two other species of Streptosyllis Webster & Benedict, 1884. The generic definition of Streptosyllis is emended to include this feature previously unknown for the genus, and an updated key to the Streptosyllis found in UK waters is provided.
