One hundred and four species belonging to at least forty-two genera comprise 13 per cent by abundance of the total benthic ostracod fauna from the continental shelf and upper slope between the Kunene River and Cape Agulhas. The remaining 87 per cent of the fauna (comprising 18 species) have previously been described in Part I of this report.
Twenty-six new species are described herein: Cytherelloidea compuncta, Australoecia fulleri, Neocaudites lordi, Neocaudites osseus, Neocaudites punctatus, Incongruellina venusta, Parakrithella simpsoni, Cytheropteron whatleyi, Cytheropteron trinodosum, Cytheropteron cuneatum, Cytheropteron frewinae, Cytheropteron aff. C. frewinae, Cytherura siesseri, Kangarina sola, Kangarina hendeyi, Hemicytherura petheri, Austroaurila rugosa, Mutilus malloryi, Urocythereis arcana, Coquimba birchi, Buntonia namaquaensis, Buntonia rogersi, Buntonia bremneri, Buntonia gibbera, Buntonia deweti, and Munseyella eggerti.
Twenty of the species have been previously recorded from the area, and fifty-eight species are left in open nomenclature.
The largest number of species of the minor taxa occurs in water shallower than 300 m, and concentrations of upper and lower depth limits of species occur at 200-300 m (outer continental shelf: mixed layer/Antarctic Intermediate Water boundary) and 500-600 m (upper continental slope: top of AAIW salinity minimum zone). There are important latitudinal range limits (boundaries to faunal assemblages) at 19,5°S (Walvis Ridge abutment), 22,5°S (Walvis Bay), 29,5-31,soS (Namaqualand shelf), and 34°S (Cape Peninsula).
