Table 2 Mean genetic distances among genetic lineages and suggested species of Aurelia. Distances derive from GTR+G (mtDNA, upper half) and HKY+G substitution model (ncDNA, lower half). The diagonale shows ncDNA variability within lineages (except for MCA which is represented by only one individual). The widespread UBI lineage (California/Pacific, France/Atlantic and Mediterranean Sea, Australia/Indian Ocean and Japan/Pacific) is best regarded as A. aurita since the locus typicus (Linne) has been described from the Mediterranean. The LIM and LAB lineages represent A. limbata and A. labiata, respectively. Lineage BOR is designated A. borealis due to its exclusive occurrence in boreal climates. MKL lineage is absent in mtDNA due to introgressive hybridization (see details in text).
