Genus Cytherelloidea Alexander, 1929 This is an important subsidiary genus in some of the Upper Cretaceous rocks of south-east Africa. It is recorded sporadically throughout the Santonian II to Maastrichtian II of Zululand and Richards Bay BH-9 borehole where it generally constitutes 1-5 per cent of the total ostracod population, but has not been found in the following areas: the Maastrichtian III of the Agulhas Bank; the late Campanian/early Maastrichtian of Igoda and Needs Camp; Campanian- Maastrichtian of the JC-1 borehole. In the Campanian-Maastrichtian sequences of Zululand, Cytherelloidea is represented by four species: C. umzambaensis, C. contorta, C. griesbachi, and. Fig. 6.
