The taxonomic identity of Stachytarpheta confertifolia Moldenke, S. chapadensis Moldenke and S. confertifolia var. puberulenta Moldenke is revised. The protologues, herbarium collections and literature were thoroughly examined, and we re-establish S. chapadensis and consider S. confertifolia var. puberulenta as a new synonym of S. chapadensis. We provide updated descriptions of the species, distribution maps and information about habitat and conservation status.
