The genus Lygdamis (Family Sabellariidae) currently contains 20 species (Hutchings et al. 2012; Capa et al. 2015). Lygdamis wirtzi Nishi and Núñez, 1999, was originally described from Madeira Island and the Canary Islands and has also been found at the Cape Verde Islands and at São Tomé Island (Wirtz 2001, 2003). New observations of this species were made while SCUBA diving at the coasts of Ascension and St Helena Islands in 2013 and 2015.
