Muellera tozziana M. J. Silva (Millettieae, Leguminosae), a new species endemic to Brazil, is described and illustrated on the basis of field studies during the taxonomic revision of the genus. The species is morphologically similar to M. denudata (Benth.) M. Sousa, but it differs and can be characterized by its falcate or oblong-falcate fruits, glabrescent with upper margin discreetly thickened; the pubescent staminal tube and free portion of the filaments and anthers; subtruncate calyx, and delicate leaves.
