Bougainvillia macloviana Lesson, 1830

Synonyms in the area: Hippocrene macloviana —Browne 1902; Vanhöffen 1910 [medusa]; Perigonimus repens —?Ritchie 1909; Jäderholm 1910 [polyp]; Bougainvillia platygaster —Zamponi 1983a [medusa] [non Bougainvillia platygaster (Haeckel, 1879) ]; Perigonimus octonus —Blanco 1994a [polyp]; Perigonimus setamus —Genzano & Zamponi 1997 [polyp].

Remarks: polyp—there are no clear morphological characters to distinguish the colonies of B. macloviana from other species of Bougainvillia and, therefore, records of the polypoid stage are dubious. The polyp was recorded as Perigonimus repens (Ritchie 1909; Jäderholm 1910) and Perigonimus octonus (Blanco 1994) in Tierra del Fuego and Malvinas (Falkland) Islands;

medusa—recorded for the Malvinas (Falkland) Islands as Hippocrene macloviana by Browne (1902) and Vanhöffen (1910). The three specimens deposited in the collections of the Museo de La Plata (Vannucci & Tundisi 1962) for off Buenos Aires were lost and their identification might be considered doubtful.

Distribution in South America: polyp—Atlantic Ocean, Argentina, from 38°S to 40.80°S, at Malvinas (Falkland) Islands, and at Tierra del Fuego islands (Hartlaub 1905; Ritchie 1909; Jäderholm 1910, 1917; Blanco 1994a; Genzano & Zamponi 1997; Genzano et al. 2009a);

medusa—Pacific Ocean, Chile, from 41.5°S to 55.84°S (Pages & Orejas 1999: Bravo et al. 2011; Palma et al. 2014a); Atlantic Ocean, Argentina, from 41°S to 55°S, and at Strait of Magellan (Browne 1902; Browne & Kramp 1939; Zamponi 1983a; Pagès & Orejas 1999; Genzano et al. 2008a).

Habitat: polyp—in the intertidal fringe, on calcareous rhodophyte Corallina officinalis and Ectopleura crocea colonies;

Medusa—commonly found in subantarctic waters (Vannucci & Rees 1961).
