Neotropical: 1) Bolivia, 2) Brazil, 3) Colombia, 4) Ecuador, 5) French Guiana, 6) Guyana, 7) Peru, 8) Suriname, 9) Trinidad and Tobago, 10) Venezuela ( Keirans 1985 b, Guerrero 1996, Robbins et al. 2003, Mastropaolo et al. 2014, Acevedo-Gutiérrez et al. 2020, Binetruy et al. 2020, Guglielmone et al. 2021).

Amblyomma crassum , Amblyomma humerale and Amblyomma sabanerae are morphologically similar taxa, and their separation is sometimes difficult ( Guglielmone et al. 2021). See also Amblyomma crassum .

The Paraguayan record of Amblyomma humerale in Berlese (1888) represents, in fact, Amblyomma dissimile , as discussed in Tonelli Rondelli (1939). Neumann (1899) described Amblyomma gypsatum , a synonym of Amblyomma humerale , from specimens allegedly collected in Uruguay but cited a locality that is not found there ( Guglielmone et al. 2021). Evans (1947) recorded Amblyomma humerale (as Amblyomma humerli , a lapsus) from Panama, but Fairchild et al. (1966) treated this record as erroneous. Vargas (1955) listed Amblyomma humerale from Mexico, but its presence in that country was not confirmed by Guzmán-Cornejo et al. (2011). Consequently, Paraguay, Uruguay, Panama and Mexico are excluded from the geographic distribution of Amblyomma humerale .
