Abstract
The evolution and phylogenetic relationships of the ticks at both the family and genus levels are contested. The genus Amblyomma and its subgenera are in a state of flux; moreover, the relationships among the three tick families are controversial due to conflicting phylogenetic support for different arrangements of the three families of living ticks. With 18 newly sequenced mitochondrial (mt) genomes of ticks included, we executed the largest mt genome phylogenetic study of ticks so far. Phylogenetic trees were inferred from seven mite mitochondrial genomes that were set as the outgroups and 146 tick mt genomes from 120 species: 153 mt genomes in total. Sixteen phylogenetic trees were inferred from 10 datasets using both maximum likelihood and Bayesian inference methods. We describe the first novel mt gene-arrangement for the metastriate Ixodidae in Amblyomma (Africaniella) transversale. Also, three unusual partial 16S rRNA gene inserts were found in the mt genome of Haemaphysalis (Alloceraea) kitaokai: we consider the possible role of past genome translocation events in the formation of these inserts. Our phylogenies revealed evidence that: (i) the genus Amblyomma is polyphyletic with respect to Amblyomma (Africaniella) transversale; (ii) the subgenus Aponomma is apparently embedded in the genus Amblyomma; (iii) Haemaphysalis (Segalia) parva and Haemaphysalis (Alloceraea) kitaokai form a clade to the exclusion of other Haemaphysalis species; and (iv) the phylogenetic position of the family Nuttalliellidae is unstable among phylogenies from different datasets.
