Silicularia bilabiata (Coughtrey, 1875)

Synonyms in the area:? Silicularia rosea —Galea et al. 2009b [non Silicularia rosea Meyen, 1834 ] [polyp].

Remarks: Vervoort & Watson (2003 p. 442–446) and Galea et al. (2009b p. 18–19) considered S. bilabiata a synonym of S. rosea Meyen, 1834 . Recently, Galea et al. (2014 p. 8–10) showed that the position of the hydrothecal rim and size of gonothecae could differentiate this species from the typical S. rosea , although this conclusion is provisional and needs further confirmation.

Distribution in South America: polyp—Pacific Ocean, Chile, at 39.95°S 73.62°W, at 43.40°S 74.08°W, in Corral and south of Chiloé (Galea et al. 2009b p. 18–19, 2014 p. 8–10); Atlantic Ocean, Argentina, no specific record (Genzano & Zamponi 1997).

Habitat: polyp—from 8m to 10m depth, on seaweed (Galea et al. 2009b p. 18–19, 2014 p. 8–10).
