In this research, the taxonomic status of the genus Dictyota in southern coastlines of Iran was studied. Taxonomy of the genus at species levels is complicated and difficult due to the high morphological plasticity in response to environmental conditions and overlapping of diagnostic characters. In this study, we combined morphological information with cytoplasmic barcoding data from DNA rbcL and psbA. We identified Dictyota acutiloba as new record and also confirmed the presence of Dictyota ciliolata in the Persian Gulf and Gulf of Oman. Our studies showed D. ciliolata species has high inter-specific morphological diversity.
