63. Ixodes cuernavacensis Kohls & Clifford, 1966 .

Neotropical: 1) Mexico (south) (Guzmán-Cornejo & Robbins 2010, Guglielmone et al. 2021).

Clifford et al. (1973) and Camicas et al. (1998) regarded Ixodes cuernavacensis as a Neotropical species, but Guglielmone et al. (2003, 2014) treated this tick as a Nearctic species. Later, Guglielmone et al. (2021) revisited this issue, finding that Clifford et al. (1973) and Camicas et al. (1998) were correct.
