45. Amblyomma geayi Neumann, 1899 .

Neotropical: 1) Brazil, 2) Colombia, 3) Costa Rica, 4) French Guiana, 5) Guyana, 6) Panama, 7) Peru, 8) Suriname, 9) Venezuela (Floch & Fauran 1958, Fairchild et al. 1966, Keirans 1985 b, Clavijo et al. 2009, Labruna et al. 2009, Miller et al. 2016, Dolz et al. 2019, Acevedo-Gutiérrez et al. 2020, Guglielmone et al. 2021).

In Brazil, adults of Amblyomma geayi and Amblyomma parkeri have sometimes been confused with those of Amblyomma longirostre, and some specimens classified as Amblyomma geayi were later identified as Amblyomma parkeri (Labruna et al. 2009) . The nymphs of these species are also morphologically similar (Martins et al. 2010, 2013); therefore, additional confusion of nymphs (and larvae) has probably occurred.
