This study analyses species in the family Eunicidae obtained in the intertidal zones of Veracruz, Mexico. The specimens collected were associated with a sabellariid Phragmatopoma caudata Morch, 1863, and collected directly by scuba diving from some coral reefs in Veracruz. Twelve species were found, six of whish are reported for the first time in the area: Eunice mutilata Webster, 1884, Eunice panamena (Chamberlin, 1919), Eunice pellucida Kinberg, 1865, Eunice unifrons (Verrill, 1900), Marphysa aransensis Treadwell, 1939 and Nematonereis unicornis (Grube, 1840). Furthermore, the descriptions of two new species of the genera Eunice and Marphysa are included.
