Similar religious movements exist in Africa claiming Jewish ancestry. Massimo Introvigne reviews a new book by Edith Bruder, The Black Jews of Africa. History, Religion, Identity (Oxford University Press, New York 2008). Here are a few interest excerpts from his review:
Black Jewish movements in Africa ... claim to descend either from the Lost Tribes or from an early immigration of Jewish tribes from Arabia or North Africa chased southwards by Islam.
The Lembas, a tribe of some 70,000 members in South Africa, also largely covered in literature about Jewish identity since DNA research published in reputable journals lent some credibility to the claim that they do indeed descend from Jewish tribes from Arabia.
Local prophets started comparing the sufferings of Israel with the sufferings of Africa
Bruder concludes that some claims of African groups to have Jews among their ancestors are not absurd.

The House of Israel in Ghana, a movement with some 800 member headquartered in Sefwi Wiaso [have] origins [that] lie in a vision by Aaron Ahotre Toakiyarafa.
In South Africa, Jewish ancestors are claimed by the members of several "Zionist" African-initiated churches who are, however, Christian. Some regard themselves as Jewish.
Other groups claiming Jewish decent are listed. The entire review can be read here.
