180. Ixodes pararicinus Keirans & Clifford, 1985

in Keirans et al. (1985).

Neotropical: 1) Argentina ( Saracho-Bottero et al. 2020, Guglielmone et al. 2021).

Guglielmone et al. (2003) included Argentina, Uruguay and Peru within the geographic distribution of Ixodes pararicinus , while Nava et al. (2017), Guglielmone & Robbins (2018), Acevedo-Gutiérrez et al. (2020) and Quintero et al. (2021a) added Colombia to the range of this tick. However, populations of Ixodes pararicinus from Uruguay were re-identified first as Ixodes aragaoi and later as Ixodes fuscipes ( Labruna et al. 2020b) . Additionally, Saracho-Bottero et al. (2020) found that bona fide populations of Ixodes pararicinus are restricted to northwestern Argentina because populations of this tick from northeastern Argentina are Ixodes affinis or a species close to it. Therefore, the presence of Ixodes pararicinus in Colombia and Peru requires confirmation, and both countries are provisionally excluded from the range of this tick.
