Resumen:
The genus Chrysolaena H. Rob. (Vernonieae, Asteraceae) is redefined to include two taxa previously placed in Lessingianthus subgen. Oligocephalus H.Rob. Additionally, a new species of the genus endemic to eastern Paraguay is described and illustrated. The new species differs from its closest relative, C. simplex (Less.) Dematteis, in its inflorescence of a single head, 3--4-seriate involucre, pilose corolla lobes and discolorous leaves, with silvery-greyish hairs on the abaxial surface.
