19. Amblyomma cajennense ( Fabricius, 1787) .

A Neotropical species previously thought to have a vast geographical distribution extending from northern Argentina to the southern USA ( Nava et al. 2014a). Adults and nymphs have chiefly been found on Mammalia (several orders); adults alone have rarely been collected from Testudines : Testudinidae ; nymphs and larvae have been taken from Carnivora : Procyonidae and Galliformes : Cracidae ; nymphs alone have been found on Carnivora : Mustelidae ( Nava et al. 2014 a, Soares et al. 2015, Martins et al. 2016, Witter et al. 2016, Binetruy et al. 2019). Amblyomma cajennense is a frequent parasite of humans.

Note: there are many redescriptions under the name Amblyomma cajennense , but several of them are problematic because this name is known to include at least another five species ( Amblyomma interandinum , Amblyomma mixtum , Amblyomma patinoi , Amblyomma sculptum and Amblyomma tonelliae ), as explained in detail in Nava et al. (2014a). The morphological separation of these species is difficult in areas of sympatry, but molecular taxonomy has proved to be a useful tool in reaching specific diagnoses. Dantas-Torres et al. (2019b) stressed the difficulties involved in morphologically separating the males and females of Amblyomma sculptum and Amblyomma cajennense sensu stricto. The redescriptions included above, apart from those of Nava et al. (2014), are from specimens collected at sites where Amblyomma cajennense sensu stricto is known to occur, but not related species.
