Abstract


Gracilaria falconii from Falcón, Venezuela, is described as a new species, based mainly on phylogenetic evidence. Morphologically, G. falconii is similar to G. mammillaris, a species previously reported from the Gulf of Mexico, the Caribbean Sea, Venezuela, and Brazil. Although G. falconii is morphologically different from phylogenetically closely related species, morphological boundaries between G. falconii and other flattened Gracilaria are not so clear.
