Synonyms in the area: Eucopella crenata —Hartlaub 1905 [non Orthopyxis crenata (Hartlaub, 1901) ] [polyp];? Campanularia tincta var. eurycalyx —Hartlaub 1905 [polyp];? Campanularia lennoxensis —Nutting 1915 p. 52–53 [non Orthopyxis lennoxensis —Vannucci Mendes 1946 = Orthopyxis sargassicola (Nutting, 1915) ] [polyp]; Orthopyxis everta —Blanco 1967a [polyp]; Campanularia (Orthopyxis) everta —Vervoort 1972 p. 87–89 [polyp] [non Campanularia everta Clark, 1876a ];?

Remarks: Millard (1971 p. 403–404) described Campanularia subantarctica and considered the species similar to Campanularia lennoxensis Jäderholm, 1903 , which has thicker perisarc than that of Millard’s species. Galea et al. (2009b p. 16–17) did not consider this difference as a valid character to distinguish both species and designated Campanularia subantarctica Millard, 1971 as a junior synonym of Campanularia lennoxensis Jäderholm, 1903 . However, Cunha et al. (2015) found that perisarc thickness is informative for delimiting species in Orthopyxis , in spite of its intraspecific variation. Even though this was not tested for C. subantarctica , here we conservatively consider these species as separate, and the names included in the synonym of C. lennoxensis provisional, pending more detailed study.

Distribution in South America: polyp—Pacific Ocean, Chile, from 43.37°S to 55.28°S (Jäderholm 1903 p. 268–269; Nutting 1915 p. 52–53; Galea et al. 2009b p. 16–17); Atlantic Ocean, Colombia, at Santa Marta coast, Argentina, from 42.75°S to 53°S, at Malvinas (Falkland) Islands (Hartlaub 1905; Blanco 1967a; Vervoort 1972; Wedler 1975; Bandel & Wedler 1987; Genzano & Zamponi 1997).

Habitat: polyp—from 12 to 119m depth, on algae and epizoic on several species of hydroids (Jäderholm 1903; Blanco 1967a; Vervoort 1972 p. 87–89; Bandel & Wedler 1987; Galea et al. 2009b p. 16–17).
