Neotropical: 1) Argentina, 2) Belize, 3) Bolivia, 4) Brazil, 5) Colombia, 6) Costa Rica, 7) Ecuador, 8) French Guiana, 9) Mexico (south), 10) Panama, 11) Paraguay, 12) Peru, 13) Suriname, 14) Trinidad and Tobago, 15) Venezuela ( Tonelli Rondelli 1931, Floch & Fauran 1958, Fairchild et al. 1966, Jones et al. 1972, Keirans 1985b, Alvarez et al. 2005, Labruna et al. 2005c, Guglielmone & Nava 2006, Guzmán-Cornejo et al. 2011, Mastropaolo et al. 2014, Ogrzewalska et al. 2014, Acevedo-Gutiérrez et al. 2020, Guglielmone et al. 2021).

Guglielmone et al. (2020, 2021) stated that authors redescribing Amblyomma calcaratum disagree about the ornamentation and shape of the female scutum. Amblyomma calcaratum and Amblyomma nodosum are morphologically close and share Neotropical territories and hosts. Fairchild et al. (1966) had previously cautioned that adults of Amblyomma calcaratum and Amblyomma nodosum can be confused with one another; consequently, uncertainty prevails concerning their precise geographic distributions.

Amblyomma calcaris was described by Nakatsudi (1942b) from a specimen collected at a Palearctic locality and is treated as a synonym of Amblyomma calcaratum in Camicas et al. (1998), a view apparently accepted by Yamauchi (2010). However, Guglielmone et al. (2021) doubted whether Amblyomma calcaris is even a member of the genus Amblyomma and followed Guglielmone & Nava (2014) in treating this name as incertae sedis.
