Dictyota dolabellana De Paula, Yoneshigue-Valentin et Teixeira is a new species of Dictyotaceae from the South Atlantic Ocean and the first denticulate species in which dolabellane diterpenes have been found. The major compound found in this species is the 4-hydroxy-7,8-epoxy-2-dolabellene. Until now, all populations of thalli containing dolabellane diterpenes had smooth margins and all species with denticulate margins produced prenylated guaiane and xeniane diterpenes. In addition, Dictyota dolabellana differs from other species by the presence of an inconspicuous denticulation irregularly located in the central to upper portions of the frond. Morphological and chemical data and comparison with type materials of other species clearly indicate the presence of a new species.
