Nearctic: 1) USA; Neotropical: 1) Argentina, 2) Belize, 3) Colombia, 4) Costa Rica, 5) Ecuador, 6) Guatemala, 7) Mexico (south), 8) Panama, 9) Peru ( Cooley & Kohls 1945, Fairchild et al. 1966, Keirans & Clifford 1978, Guzmán-Cornejo & Robbins 2010, Nadolny & Gaff 2018, Saracho-Bottero et al. 2020, Guglielmone et al. 2021).

The name Ixodes affinis most probably represents a complex of species distributed in the Nearctic and Neotropical Regions ( Saracho-Bottero et al. 2020).

The Japanese record of Ixodes affinis by Kishida (1930) is considered a diagnostic error ( Yamaguti et al. 1971, Guglielmone et al. 2021).
