Ceramium brevizonatum var. caraibicum H.E.Petersen & BØrgesen in BØrgesen, Dansk Botanisk Arkiv 4 (7): 29-30, fig. 11 ( BØrgesen 1924 ) . TYPE LOCALITY . — Dominican Republic . Beata Island ( Silva et al . 1996: 391 ). HOLOTYPE . — Dansk Botanisk Arkiv 4 (7): 30, fig. 11 ( BØrgesen 1924 ) . NOTES This was morphologically characterized by Schneider (2004 : figs 5-7) based on material from Bermuda , showing the nodal development and the presence of pseudoperiaxial cells. We chose a sequence (GenBank[ AF 259491]) from Yucatan , Mexico , to represent this species as it was obtained from close to the type locality, Honduras , and showed 3-4% genetic divergence ( rbc L ) from Pseudoceramium brevizonatum (H.E.Petersen) Barros-Barreto & Maggs , comb. nov. and P. oliveirarum Barros-Barreto, Maggs & M.A.Jaramillo , gen. nov., sp. nov.
