The African species of the moss genus Schwetschkea are revised based on morphological features of the gametophye and sporophyte. The genus is placed in the Brachytheciaceae. Three species are recognized, S. fabronioides (S. schweinfurthii, S. monbuttoviae, S. brotheri, syn. nov.), S. usambarica, and S. grateloupii. A key to these species is provided. Schwetschkea fabronioides is reported for the first time from South America from a Brazilian collection. Les auteurs révisent les espèces de mousses africaines du genre Schwetschkea sur la base des caractéristiques morphologiques de leurs gamétophytes et de leurs sporophytes. Le genre se situe dans les Brachytheciaceae. On reconnaît trois espèces, les S. fabronioides (S. schweinfurthii, S. monbuttoviae, S. brotheri, syn. nov.), S. usambarica et S. grateloupii. On propose une clé pour l'identification de ces espèces. Le Schwetschkea fabronioides fait l'objet d'une première mention pour l'Amérique du Sud, à partir d'une collection du Brésil.
