To develop molecular identification tools for Hydroides, the entire mitochondrial genomes of eight Hydroides species were sequenced by next-generation sequencing and the resultant reference sequences were used to design new taxon-specific COI primers. Analyses of mitochondrial genomes of Hydroides showed a substantial rearrangement in gene order and numerous rarely reported large intergenic regions when compared with genomes of other known polychaetes. Using the newly designed primers, a COI barcoding database including 45 species of Hydroides was established and further used to explore cryptic speciation and invasion pathways in Hydroides. In particular, COI sequence data revealed the existence of two cryptic species in the common global invader Hydroides dianthus and suggested that the native range of H. dianthus sensu stricto is the Mediterranean rather than the Atlantic coast of the USA as historically assumed.
