| Resumo: |
The coast of Espirito Santo State is located in a biogeographic transition zone presenting high diversity. A renewed interest in this region occurred in the 1990s, resulting in various new records and new species descriptions added to the Brazilian marine flora. The study of the infralitoral of this region is just beginning, and a detailed exploration with use of Scuba diving is revealing a flora containing many little-known taxa, particularly of red algae. As a first result, Predaea feldmannii Børgesen is being described for the Brazilian coast. The occurrence of the genus Predaea in Brazil has been considered with restriction since representatives of this genus had been referred only once by Howe & Taylor in 1931, being first considered as Platoma. The occurrence of Predaea in Brazil is now confirmed, and its vegetative and reproductive structures are described in detail. Predaea feldmannii can be recognized by having gonimoblast initial formed on a bulge of the connecting filament, cortical filaments of nearly equal lengths, lack of gland cells, dense clusters of nutritive cells borne only on cells immediatelly contiguous to the auxiliary cell, and a three-celled carpogonial branch.
