Rhodymenia discigera J. Agardh, 1841: 13 (`Rhodomenia') (lectotype locality: Cape of Good Hope, South Africa fide J. Agardh, 1847: 13, footnote).—Krauss, 1846: 209.
Callophyllis discigera (J. Agardh) J. Agardh, 1847: 13.—Dickie, 1874b: 196.— Barton, 1893: 141.
Thamnophyllis discigera (J. Agardh) R. Norris, 1964: 110–113, figs. 27–36, pl. 6 (including Indian Ocean record).
INDIAN OCEAN DISTRIBUTION: Mauritius, South Africa.
Note: According to R. Norris (1964: 110), this species does not occur east of Cape Agulhas so that the Krauss record from Knysna, repeated by Barton, seems dubious.
