Ralph (1956) included  Eucopella reticulataHartlaub, 1905in the synonymy of  Silicularia bilabiata(Coughtrey, 1874); later Vervoort & Watson (2003) and Galea et al.(2009b p. 18–19) included  Silicularia bilabiata(Coughtrey, 1874)and  Eucopella reticulataHartlaub, 1905in the synonymy of  Silicularia roseaMeyen, 1834. Since it is still not clear if  S. bilabiataand  S. roseaare conspecific, here we considered these species separately and their synonymy provisional, pending more detailed study. See also remarks of  Silicularia bilabiata(Coughtrey, 1874). Distribution in SouthAmerica: polyp—Pacific Ocean, from the Strait of Magellan to 56°S (Jäderholm 1903 p. 271–272; Hartlaub 1905 p. 572–578; Galea et al.2014 p. 10); Atlantic Ocean, at 6ºS off CapeSan Roque, from 48°S to 56°S (Meyen 1834; Allman 1888; Pfeffer 1889; Marktanner-Turneretscher 1890; Hartlaub 1905; Jäderholm 1905; Blanco 1964, 1994a; Stepanjants 1979; Genzano & Zamponi 1997; Seo 2003; Cunha et al.2015). Habitat: polyp—from intertidal zone to 40mdepth on  Macrocystis pyrifera(Allman 1888; Jäderholm 1903 p. 271–272; Hartlaub 1905 p. 572–578; Stepanjants 1979; Galea et al.2014 p. 10).
