Abstract

In September 2018, polychaeta worms of the family Sabellidae—Laonome xeprovala Bick & Bastrop, 2018—were found in the Luga Bay (Gulf of Finland, Baltic Sea). This species was previously been recorded in Europe, but the eastern most point of its discovery was the Gulf of Wislin—the southeastern region of the Baltic Sea. The article presents the main morphological description and distribution of this species in the investigated area.
