The morphological diagnosis of Amblyomma dissimile can be difficult, and this tick has been confused with several other species of Amblyomma , especially Amblyomma rotundatum , while some authors, such Camicas et al. (1998) , have not recognized Amblyomma dissimile as a valid name ( Guglielmone et al. 2021 ). Guglielmone & Nava (2014) listed 11 synonyms of Amblyomma dissimile , one of which, Amblyomma trinitatis , is treated as valid in Camicas et al. (1998) . Neumann (1911a) erroneously considered Amblyomma dissimile a synonym of Amblyomma cooperi , which in fact is a synonym of Amblyomma dubitatum . Capriles & Gaud (1977) stated that Amblyomma dissimile appears to be extinct in Puerto Rico . Keirans (1985b) noted that records of this tick from India in the Nuttall Collection are incorrect, and the same can be said for records of Amblyomma dissimile from the Philippines in Neumann (1899 , 1911a ). Scott & Durden (2015) allegedly found a nymph of Amblyomma dissimile on a bird in Canada , but this diagnosis is treated as doubtful in Guglielmone et al. (2020 , 2021).
