The systematic positions of Cladophoropsis robusta and Willeella mexicana, both occurring along the tropical Pacific coast of America, have long been uncertain. Willeella mexicana has been generally accepted as a synonym of C. robusta, which is currently placed in the genus Struveopsis. Reinvestigation of type material and recently collected specimens from Mexico and Panama, including culture observations, along with a molecular phylogenetic analysis inferred from rDNA ITS1-5.8S-ITS2 sequences, confirm that both taxa belong to the same, morphologically variable species. Thallus architecture ranges from stipitate, Struveopsis-like blades (produced by apical cell divisions and formation of opp..
