Type locality: “V-17-51. Latitude 55°17.5'S, longitude 66°00'W, at 205-207 meters, off the southeast end of Tierra del Fuego, Argentina.”
Depth range: 95 - 947 m

Magellania sp. Blochmann, 1912

Type locality: South Georgia, “Deutschen Station 1882-1883”.
Depth range: 275 - 970 m

Waldheimia smithii Pfeffer in Martens & Pfeffer, 1886
Aerothyris (?) smithi: Allan, 1939
Aneboconcha smithi: Zezina (1980)

* The original species name is smithii and thus must be used as it is according to the article 31.1.1. of the International code of Zoological Nomenclature (1999): it has been formed from a personal name that is Latin.

Foster (1989) pointed out that “A better understanding of this species is particularly vital in order to adequately evaluate a number of somewhat similar species that occur in the same area that may be variants of Magellania venosa. These similar specie include: Waldheimia smithi Pfeffer, 1866 (= Anecoboncha smithi Zezina, 1980); Magellania wyvillei Davidson, 1878; Anecoconcha obscura Cooper, 1973a; Syntomaria curiosa Cooper, 1982; and Dysritosia secreta Cooper, 1982.”

Type locality: Kerguelen
Depth range: 3 - 15 m

Allan (1939) attributed the specimens figured by Eichler (1911) to a new species of the genus Aerothyris Allan, 1939 under the name A. eichleri, without discussing this change and providing a diagnosis. Eichler's specimens were sampled at the station "Gauss" at less than 10 m depth, in Observatory Bay, by the “Deutsche Südpolar-expedition (1901-103). This bay was named in 1874 by the Challenger Expedition, today “baie de l'Observatoire”, Kerguelen Islands (France).
Foster (1974) pointed out that these specimens are simply an elongated form of Magellania kerguelensis. Cooper (1981) considered eichleri as synonymous of Aerothyris kerguelensis. Following Allan's statement, Zezina (1980) attributed the specimens collected in Kerguelen islands to Aneboconcha eichleri (Allan, 1939), considering that the specimens figured by Eichler (1911) are not Waldheimia kerguelensis Davidson, 1878. Nevertheless no diagnosis is provided.
Until more investigations on this species, Eichler's (1911) specimens are considered as belonging to Aerothyris kerguelensis Davidson, 1878.
Hiller (1994) indicated that A. kerguelensis is the most common of the brachiopods and is the species that extends over the greatest depth range, from less than 50 m deep to more than 500 m. It is particularly abundant in the shallow area of Marion and Prince Edward Islands (South Africa).
