Integrative Taxonomy of <i>Dermacentor variabilis</i> (Ixodida: Ixodidae) with Description of a New Species, <i>Dermacentor similis</i> n. sp.

Abstract Dermacentor variabilis is the most widely distributed three-host tick in North America, and transmits a variety of pathogens. Within United States, this species has discontinuous distribution, widespread east Rocky Mountains with few populations west Rockies. Phylogenetic evidence based on individual markers or relatively small data sets suggested that at both sides geographic barrier may correspond to two different species. In study, we further explore hypothesis using an integrative taxonomy framework. Both molecular (mitochondrial nuclear markers) morphological analyses specimens collected from central-eastern western states were performed delimitation taxon. Results these consistent, provide strong D. actually corresponds Herein, are described as new species, similis n. sp. The usefulness context also discussed.
