Tillandsia bonita is described as a new species and is illustrated. It is compared with Tillandsia didisticha, which we assume is the morphologically most similar species. The new species is the ninth taxon of this genus recorded for the flora of the state of Mato Grosso do Sul, central-western Brazil. Illustrations and a brief discussion on the leaf anatomy of the species are provided. Two additional species that have been overlooked by previous authors are included in the list of Bromeliaceae of Mato Grosso do Sul and an updated key for Tillandsia from that state is presented.
