12. Ixodes angustus Neumann, 1899 .

Nearctic: 1) Canada, 2) USA; Palearctic: 1) Japan (except the Ryukyu Islands), 2) Russia ( Yamaguti et al. 1971, Filippova 1977, Keirans & Clifford 1978, Robbins & Keirans 1992, Kolonin 2009, Takano et al. 2014, Lindquist et al. 2016, Tsapko 2020).

Early Neotropical records of Ixodes angustus in Neumann (1901) and Lahille (1905) are misidentifications of Ixodes loricatus , an error amended in Neumann (1910a) , but overlooked by Yamaguti et al. (1971), who treated Ixodes angustus as present in Argentina. Uncritical reviews, as in Muñoz & Casasnueva (2001), continue to claim that Ixodes angustus occurs in the southern Neotropics. Estébanes-González & Cervantes (2005) allegedly found Ixodes angustus in the Neotropical part of Mexico, but Guzmán-Cornejo et al. (2007) reexamined the specimens classified as Ixodes angustus by Estébanes-González & Cervantes (2005), finding that they do not represent this species. Nevertheless, the erroneous records of Ixodes angustus in Estébanes-González & Cervantes (2005) were considered valid in Rivas & Guzmán-Cornejo (2016) due to a typographical error (C. Guzmán-Cornejo personal communication to A.A. Guglielmone). Kim et al. (2020) listed Ixodes angustus as found in South Korea, but its presence in that country requires confirmation, and South Korea is excluded from the range of this tick.
