• Ticks are blood-sucking ectoparasites with significant medical and veterinary importance, capable of transmitting bacteria, protozoa, fungi, and viruses that cause a variety of human and animal diseases worldwide. In the present study, we sequenced the complete mitochondrial (mt) genomes of five hard tick species and analyzed features of their gene contents and genome organizations. The complete mt genomes of Haemaphysalis verticalis , H. flava , H. longicornis , Rhipicephalus sanguineus and Hyalomma asiaticum were 14855 bp, 14689 bp, 14693 bp, 14715 bp and 14722 bp in size, respectively. Their gene contents and arrangements are the same as those of most species of metastriate Ixodida, but distinct from species of genus Ixodes . Phylogenetic analyses using concatenated amino acid sequences of 13 protein-coding genes with two different computational algorithms (Bayesian inference and maximum likelihood) revealed the monophylies of the genera Rhipicephalus , Ixodes and Amblyomma , however, rejected the monophyly of the genus Haemaphysalis . To our knowledge, this is the first report of the complete mt genome of H. verticalis . These datasets provide useful mtDNA markers for further studies of the identification and classification of hard ticks.
