69. Rhipicephalus sanguineus (Latreille, 1806): Nearctic: 1) Mexico (north), 2) USA; Neotropical: 1) Argentina, 2) Brazil, 3) Chile, 4) Uruguay; Palearctic: 1) Croatia, 2) France, 3) Italy, 4) Portugal, 5) Spain, 6) Switzerland (Nava et al. 2018, Sánchez-Montes et al. 2021 b, Krčmar et al. 2022). Rhipicephalus sanguineus sensu stricto was redescribed morphologically and molecularly by Nava et al. (2018), who also selected a neotype from a French population, thus providing the only bona fide description of this species. Rhipicephalus sanguineus is the type species of a group of morphologically very close ticks that constitute the Rhipicephalus sanguineus species group. Additionally, there are many populations of Rhipicephalus sanguineus sensu lato worldwide, some of which surely belong to Rhipicephalus sanguineus sensu stricto, and molecular data provided by Nava et al. (2018) will be vital to the specific diagnosis of these populations. In any event, the geographic range of Rhipicephalus sanguineus sensu stricto is broader than the 12 countries listed above would appear to indicate, although there is no evidence that the Rhipicephalus sanguineus reported from Belize by Polsomboon et al. (2017) are sensu stricto because those collections have not been compared with the data in Nava et al. (2018).
