Molecular analysis confirms Laurenciella marilzae (Rhodophyta, Rhodomelaceae) in the Mediterranean Sea, a species often misidentified as Laurencia dendroidea

It was noted that Mediterranean specimens collected at different stations from around Sicily, Italy and referred to as Laurencia dendroidea (as Laurencia majuscula) were similar to the recently described species Laurenciella marilzae. Presented in this study are the results of an integrative approach using both morphology and molecular data (COI-5P + rbcL) to establish which taxon these specimens should be referred to. Molecular analyses show these specimens belong to Laurenciella, and strongly suggest they are within the species L. marilzae. Morphological examinations of these Mediterranean specimens were also detailed and found to support the conclusion that they belong to L. marilzae.
