3. Amblyomma americanum (Linnaeus, 1758). Nearctic: 1) USA (Lado et al. 2020). Although Camicas et al. (1998) treated Amblyomma americanum as a Nearctic and Neotropical species, Guglielmone et al. (2003, 2014, 2021) listed and discussed several records of this tick from Neotropical countries and a few from other zoogeographic regions, including Russia (Palearctic), arguing that Amblyomma americanum is a Nearctic species. However, Lindquist et al. (2016) analyzed the several records of Amblyomma americanum from Canada, concluding that there are no stable populations of this tick in that country. There are also several records of Amblyomma americanum from northern Mexico, but there is no evidence that natural, permanent populations exist in that country. García-Rejón et al. (2021) reported specimens from Mexico (south) but this species’ presence there needs verification. Consequently, Canada, Mexico (north) and Mexico (south) are not included within the range of Amblyomma americanum.
