Abstract

A neotype specimen is designated for the coralline alga Sporolithon mediterraneum Heydrich (Sporolithales, Corallinophycidae, Rhodophyta) and critically examined here, since the original holotype specimen apparently has been destroyed. The neotype specimen was collected in a mesophotic rhodolith bed near Gorgona Island (Tyrrhenian Sea, Mediterranean). Additional specimens were collected in a rhodolith bed in the Menorca Channel (Western Mediterranean) and were used to confirm the identification of the neotype. Molecular analyses of psbA and rbcL with all Sporolithon species for which there are currently sequence data, including S. ptychoides and S. molle supported the designation of this neotype and the circumscription of this Mediterranean species. Additional specimens from Menorca Channel were resolved as conspecific based on psbA sequences. The morpho-anatomical data presented indicated that S. mediterraneum can be also distinguished from the type species Sporolithon ptychoides Heydrich and Sporolithon molle (Heydrich) Heydrich, the only two other species previously reported from the Mediterranean Sea, by the occurrence of 5–6 cell paraphyses and larger stalk cells. A consideration of the status of Sporolithon in the Mediterranean region is also discussed.

期刊介绍： Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
