In this manuscript three taxonomic changes are proposed based on multivariate and univariate analyses of morphological characters from collections of Terminalia in the Neotropics. Sixty-six morphological characters were examined from Terminalia reitzii, T. triflora, and T. uleana, of which only 12 were considered informative for morphometric evaluation and analyzed by the Kruskal-Wallis test and principal components analysis. As a result, T. reitzii and T. uleana are synonymized under T. triflora, and we propose a new circumscription for T. sect. Diptera. In addition, morphological, distribution and conservation aspects of T. triflora are discussed. A key to the South American species of T. sect. Diptera is presented.
