A new species of Evolvulus from the Brazilian Cerrado, a savanna biodiversity hotspot, is described here. Evolvulus aureus sp. nov. is similar to E. passerinoides, both found in Cerrado, and share erect stems (also decumbent in E. passerinoides), branched at the base, leaves spiral, flat, with acute apex and leaf base rounded, and axillary flowers. They can be distinguished by the indument type and by its color when herborized, shape of the leaf blade, visibility of secondary veins, sepal length, and anther shape. This new species is circumscribed into E. sect. Passerinoidei based on erect stem, axillary and solitary flowers, and funnelform corolla. A diagnosis, morphological description, illustrations, taxonomic notes, informal conservation status, distribution map, and an identification key are provided.
