60. Amblyomma inornatum (Banks, 1909) .
Nearctic: 1) Mexico (north), 2) USA; Neotropical: 1) Costa Rica, 2) Guatemala, 3) Mexico (south) (Cooley & Kohls 1944, Eads & Borom 1975, Alvarez et al. 2005, Voltzit 2007, Guzmán-Cornejo et al. 2011, Guglielmone et al. 2021).
Guglielmone et al. (2003) suggested that specimens of Amblyomma inornatum collected in Costa Rica and Guatemala may have been confused with morphologically related species, while Guglielmone et al. (2021) stated that Neotropical data concerning this tick should be considered provisional.
Kolonin (2009) and Guglielmone & Robbins (2018) included Panama within the geographic distribution of Amblyomma inornatum . It is true that Fairchild (1943) listed this tick as found in Panama, but Fairchild et al. (1966) and Bermúdez et al. (2018) did not regard Amblyomma inornatum as a Panamanian tick. French Guiana and Guyana are included within the range of Amblyomma inornatum by Delabra-Vaca et al. (1996), but this tick has yet to be collected there, while Muñoz & Casanueva (2001) misinterpreted Jones et al. (1972) when stating that Amblyomma inornatum has been found in Venezuela. Therefore, Panama, French Guiana, Guyana and Venezuela are excluded from the range of Amblyomma inornatum .
