Amblyomma parkeri Fonseca and Aragao 1952

90. Amblyomma parkeri Fonseca and Aragão, 1952a.

A Neotropical species whose adults are usually found on Rodentia: Erethizontidae; most nymphs have been collected from Erethizontidae and Primates: Atelidae, and most larvae have been taken from Passeriformes (several families). Adults and nymphs have been recovered from Primates: Atelidae; adults alone have been taken from Carnivora: Procyonidae; nymphs alone have been found on Didelphimorphia: Didelphidae, Primates: Pitheciidae, Accipitriformes: Accipitridae, and Galliformes: Cracidae; and larvae alone have been collected from Caprimulgiformes: Trochilidae. Amblyomma parkeri was listed as a very rare parasite of humans in Guglielmone and Robbins (2018), but several new cases of human parasitism by nymphs of this tick have been reported from Brazil by Reck et al. (2018) and Borsoi et al. (2019).

Note: Amblyomma parkeri is a valid species but was treated as doubtful in Kolonin (2009) and was excluded from the list of Neotropical ticks in Voltzit (2007). However, it was definitively reinstated by Labruna et al. (2009), who found Amblyomma parkeri extensively confused with Amblyomma geayi in southern Brazil. Amblyomma geayi, Amblyomma longirostre, Amblyomma parkeri and Amblyomma romarioi are morphologically similar species, and separation of adults and especially immature stages is difficult.
