Abstract There are different ways in which black women in the Diaspora have given expression to their erotic fascination with other women. In this article two idealtypical expressions of black female homosexuality and the outlines of their underlying cosmologies are sketched: mati-ism and black lesbianism. Mati (or matisma) is the Sranan Tongo word for women who have sexual relations with other women, but who typically also will have had or still have relationships with men, simultaneously. More often than not they will also have children. While both types can only be understood via a constructionist view of homosexuality, the institution of mati-ism will be shown to have retained more Afrocentric, working class elements, while black lesbianism has more middle class, Eurocentric features.
