Several records of Haemaphysalis juxtakochi have been published under the name Haemaphysalis kochi Arag ã o, 1908c, a preoccupied name, or Haemaphysalis kohlsi, a name proposed by Arag ã o & Fonseca (1951) but considered a synonym of Haemaphysalis juxtakochi .

Camicas et al. (1998) treated Haemaphysalis juxtakochi as a Neotropical tick. In fact, the great majority of records are from specimens collected in the Neotropical Region, and its presence in northern Mexico (Kohls 1960b) and the USA (Keirans & Restifo 1993) is based on a record from deer in each country. Consequently, Haemaphysalis juxtakochi is provisionally treated here as a Nearctic species.

Molecular evidence in Thompson et al. (2020) indicates that more than one species may exist under the name Haemaphysalis juxtakochi .
