67. Rhipicephalus sanguineus (Latreille, 1806). A Nearctic, Neotropical and Palearctic species, all of whose parasitic stages are usually found on Carnivora: Canidae, mainly on the domestic dog, with many unconfirmed records from other hosts, including humans, but see note below. M: Nava et al. (2018), but see note below F: Nava et al. (2018), but see note below N: Nava et al. (2018), but see note below L: Nava et al. (2018), but see note below Note: this species was originally named Ixodes sanguineus by Latreille (1806) for a specimen whose sex is impossible to determine and was given its current status – Rhipicephalus sanguineus – by Koch (1844a), this being a name that was supported by its usage. Nava et al. (2018) reinstated the species and designated a neotype. These authors also state that Rhipicephalus sanguineus sensu stricto has been found in the USA (Nearctic), Argentina, Brazil, Chile and Uruguay (Neotropical) and France, Italy, Portugal, Spain and Switzerland (Palearctic), but this geographic distribution is certain to expand in the near future. The morphological separation of this species from related taxa has proved difficult, and bona fide diagnosis should therefore include molecular evidence.
