“…However, it is important to note that in this case, a single haplotype (H2) concentrates most of the diversity and could be inferred as the differentiation centre, since all mentioned countries are included in this haplotype. This has been proposed for other biological systems, with some unique haplotypes from South America (Colombia and Brazil) as tip haplotypes [ 35 , 36 , 37 ]. This phenomenon could be explained by a long-distance founding event, based on the great vagility of the hosts, such as in several populations of Amblyomma maculatum within the US [ 38 ].…”

“…For all following analyses, we only used the multiple alignment of the R. sanguineus Tropical Lineage and R. sanguineus s.s. from the Nearctic and Neotropical regions, without the outgroup. To provide a more detailed account of the genetic diversity and to detect possible populations and subpopulations in the R. sanguineus Tropical Lineage and R. sanguineus s.s., an ordination PCoA of the eigenvalue scores was performed in PAST 4.04 [55], based on the Euclidean distances [37].…”

The Rhipicephalus sanguineus group encompasses at least 12 validated species of Palearctic and Afrotropical hard ticks, which are relevant in veterinary medicine and public health. The taxonomy of R. sanguineus s.s., has been particularly intensely debated, due to its wide geographic distribution, morphological variants, parasite-host associations, and its capacity and vectorial competence for the transmission of several pathogens. By sequencing mitochondrial markers, it was possible to identify the existence of multiple lineages, among which the Tropical and the Temperate lineages stand out, particularly in America. However, the northern limit between these lineages is not clear due to the lack of extensive sampling across Mexico. For this reason, the aim of the present study was to determine the genetic diversity and structure of the R. sanguineus group in Mexico and to compare it with the populations reported in the Americas, in order to propose the northern limit of the R. sanguineus Tropical lineage and the potential regions of sympatry with R. sanguineus s.s. The findings of this study now confirm the presence of R. sanguineus s.s. in Mexico, showing a subtle genetic structure and high genetic diversity throughout its distribution in the Americas. In contrast, the Tropical lineage seems to be genetically less diverse in its overall distribution in the Americas. The genetic diversity of these two independent lineages could have important epidemiological implications in the transmission of tick pathogens.
