108. Amblyomma rotundatum Koch, 1844a . Nearctic: 1) USA;

Neotropical: 1) Argentina, 2) Bolivia, 3) Brazil, 4) Colombia, 5) Costa Rica, 6) Dominica, 7) French Guiana, 8) Grenada, 9) Guadeloupe, 10) Guatemala, 11) Jamaica, 12) Martinique, 13) Mexico (south), 14) Montserrat, 15) Panama, 16) Paraguay, 17) Peru, 18) Suriname, 19) Trinidad and Tobago, 20) Venezuela; remote islands: 1) Pacific Ocean Islands (north) ( Bequaert 1938, Morel 1967, Kohls 1969c, Jones et al. 1972, Keirans 1985 b, Need et al. 1991, Oliver et al. 1993, Nava et al. 2007, Guglielmone & Nava 2010, Guzmán-Cornejo et al. 2011, Durden et al. 2015, Kelehear et al. 2017 b, Benavides-Montaño et al. 2018, Binetruy et al. 2019, Ogrzewalska & Bermúdez 2019, Guglielmone et al. 2021).

Several records of Amblyomma rotundatum have been published under the synonym Amblyomma agamum ( Guglielmone & Nava 2014) .

Pietzsch et al. (2006) recorded 25 males, nine females and four nymphs of Amblyomma rotundatum from Honduran toads (the only record found for this tick in that country). However, because Amblyomma rotundatum is a parthenogenetic species, the number of male ticks collected is difficult to justify, and the diagnosis of Pietzsch et al. (2006) is treated here as a misidentification. We therefore exclude Honduras from the geographic distribution of Amblyomma rotundatum . The record of Amblyomma rotundatum , under the name Amblyomma agamum , in Uruguay by Vogelsang (1928) has not been confirmed; therefore, Venzal et al. (2003) excluded Amblyomma rotundatum from their list of Uruguayan ticks.
