Neumann (1899, 1901) allegedly found Amblyomma varium in Chile and Argentina, records that were later repeated by several authors, but those countries are outside the range of this tick, as discussed in Onofrio et al. (2008) and Nava et al. (2017). Vargas (1955) included Mexico within the geographic distribution of Amblyomma varium, but its presence in that country was not supported by Guzmán-Cornejo et al. (2011).
