The Catholic hierarchy of South Africa is entirely Latin, composed of five ecclesiastical provinces, each under a Metropolitan Archbishop, with a total of 20 suffragan South African dioceses and an exempt pre-diocesan apostolic vicariate, as well as three suffragans (two dioceses, one apostolic vicariate) from below-mentioned neighbor states (fellow former British colonies).
Botswana has only one diocese and one apostolic vicariate, both suffragan of the South African Metropolitan Archbishop of Pretoria.
Swaziland only has a single diocese, suffragan of the South African Metropolitan of Johannesburg.
Neither of those warranting a nation Episcopal conference, their tiny episcopates partakes in the transnational Episcopal Conference of South[ern] Africa, despite its one-nation name.
None of them has an Eastern Catholic jurisdiction, only South Africa has an exempt Military ordinariate.
There are no titular sees. All defunct jurisdictions have current Latin successor sees.
There also is an Apostolic Nunciature to South Africa as papal diplomatic representation at embassy-level in the national capital Pretoria. There formally are an Apostolic Nunciature to Botswana and an Apostolic Nunciature to Swaziland, but both are vested in the Apostolic Nunciature to South Africa (as are the Apostolic Nunciature to Namibia and to the kingdom of Lesotho, which have their own Episcopal conferences).
