Silicularia rosea Meyen, 1834

Synonyms in the area: Hypanthea hemispherica Allman, 1888 [polyp]; Hypanthea georgiana Pfeffer, 1889 [polyp]; Hypanthea atlantica Marktanner-Turneretscher, 1890 [polyp]; Hypanthea repens —Marktanner-Turneretscher 1890; Jäderholm 1903 p. 271–272 [polyp]; Eucopella reticulata Hartlaub, 1905 [polyp]; Silicularia hemispherica —Hartlaub 1905 p. 576–578; Jäderholm 1905 [polyp]; Silicularia hemipherica —Genzano & Zamponi 1997 [incorrect subsequent spelling] [polyp]; Silicularia reticulata —Genzano & Zamponi 1997 [polyp].

Remarks: the female gonotheca of the species Eucopella reticulata Hartlaub, 1905 presents the typical shape of an immature gonotheca, according to the description provided by Ralph (1956) and Blanco (1967e) on the variation in the shape of the female gonothecae of Silicularia bilabiata (Coughtrey, 1874) . Ralph (1956) included Eucopella reticulata Hartlaub, 1905 in 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 reticulata Hartlaub, 1905 in the synonymy of Silicularia rosea Meyen, 1834 . Since it is still not clear if S. bilabiata and S. rosea are 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 South America: 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 Cape San 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 40m depth on Macrocystis pyrifera (Allman 1888; Jäderholm 1903 p. 271–272; Hartlaub 1905 p. 572–578; Stepanjants 1979; Galea et al. 2014 p. 10).
