Amblyomma dubitatum Neumann, 1899 . Neotropical: 1) Argentina , 2) Bolivia , 3) Brazil , 4) Paraguay , 5) Uruguay ( Nava et al. 2010 a , Martins et al. 2014, Mastropaolo et al. 2014 , Gruhn et al. 2019 , Guglielmone et al. 2021 ). Several records of Amblyomma dubitatum have been published under the name Amblyomma cooperi , as noted by Camicas et al. (1998) and Estrada-Peña et al. (2002) . Neumann (1899) described Amblyomma dubitatum from a female tick collected in Spain , but he was not convinced about the origin of this specimen. Amblyomma dubitatum was treated as an African or Oriental species by various authors until Camicas et al. (1998) listed it as a Neotropical species, a view supported by Estrada-Peña et al. (2002) , who redescribed this tick, as discussed in Guglielmone et al. (2003) .
