Haemaphysalis chordeilis ( Packard, 1869 ) . Nearctic: 1) Canada , 2) USA ( Cooley 1946 , Kohls 1960 b , Lindquist et al. 2016). Guglielmone et al. (2020) stated that several records of Haemaphysalis chordeilis have been published under the name Haemaphysalis cinnabarina or Haemaphysalis cinnabarina punctata . Camicas et al. (1998) listed Haemaphysalis chordeilis as a Nearctic and Neotropical tick. There is an alleged Neotropical record of Haemaphysalis chordeilis (as chordeiles , a lapsus ) in Beatty (1944) , but in the opinion of Hoogstraal (1973b) and Keirans & Restifo (1993) , no bona fide specimens of this tick have been collected outside the Nearctic Region, a view that is endorsed here. Kolonin (2009) included Mexico within the range of Haemaphysalis chordeilis . There is a record of this tick from the Nearctic portion of Mexico in Hoffmann (1962) , but it has not been confirmed; therefore, Mexico is provisionally excluded from the geographic distribution of Haemaphysalis chordeilis .
