INDIAN OCEAN DISTRIBUTION: South Africa.
Note: Abbott (1976b) merged Callithamniella Feldmann-Mazoyer (1938: 1120) with Grallatoria Howe (1920: 560), which she assigned to the tribe Sphondylothamnieae, but Schneider (1984: 459) retained both genera, believing that in the type species of Grallatoria (G. reptans Howe, l.c.; type locality: Great Ragged Island, Bahamas) indeterminate erect axes never arise on determinate axes, whereas they do so regularly in the type species of Callithamniella (C. tingitana (Schousboe ex Bornet) Feldmann-Mazoyer, l.c.; Callithamnion tingitanum Schousboe ex Bornet, 1892: 329–330; type locality: Tangier, Morocco). While showing that this distinction does not exist, Wynne & Ballantine (1985) cited other differences between the two genera. Grallatoria was assigned by those authors to the tribe Wrangelieae, while Callithamniella was assigned by Stegenga (1988: 378) to the tribe Heterothamnieae.
