133. Ixodes loricatus Neumann, 1899 .

Neotropical: 1) Argentina, 2) Brazil. 3) Paraguay, 4) Uruguay (Guglielmone et al. 2011, 2021, Fonseca et al. 2020).

Ixodes loricatus was thought to be distributed from southern Argentina to southern Mexico (Guglielmone et al. 2003), but it was later found that this species’ geographic distribution is restricted to eastern South America (Guglielmone et al. 2011).

A record of Ixodes loricatus from southern Mexico in Onofre-Barragán (2015) was treated as a diagnostic error in Guglielmone et al. (2021), while this species’ presence in Colombia (Acevedo-Gutiérrez et al. 2020) requires confirmation; both countries are here considered outside the range of Ixodes loricatus .
