Synonyms in the area:? Campanularia volubilis var. antarctica Ritchie, 1913 —Blanco 1964 [polyp].
Remarks: according to Calder et al. (2003), the record given by Fraser (1938a) may be a misidentification because the specimens are infertile and C. volubilis (Linnaeus, 1758) is a species of high latitudes and cold waters. Peña-Cantero et al. (2004) assigned the record given by Blanco (1964), with doubt, to the species Campanularia antarctica Stechow, 1922.
Distribution in South America: polyp—Pacific Ocean, Ecuador, from 1°S to 1.5°S in Isla Floreana (Fraser 1938a; Calder et al. 2003); Atlantic Ocean, Argentina, at Punta Peñas, San Julián coast (Blanco 1964; Genzano & Zamponi 1997).
Habitat: polyp—low tide, on hydroids of the family Sertulariidae (Fraser 1938a; Blanco 1964; Calder et al. 2003).
