87. Amblyomma ovale Koch, 1844a. A Neotropical species with a few records from the Nearctic Region whose adults are usually found on Carnivora: Canidae and Felidae, and Perissodactyla: Tapiridae; larvae and nymphs are commonly recovered from Rodentia: Cricetidae and Echimyidae. All parasitic stages have been found on Car-nivora: Canidae and Procyonidae, Rodentia: Cricetidae and Echimyidae, and Passeriformes: Thraupidae; adults and nymphs have been recovered from Carnivora: Felidae, Mustelidae and Procyonidae, and Perissodactyla: Tapiridae; adults and larvae have been found on Galliformes: Cracidae; adults alone have been taken from Mammalia (several orders), with rare records from Gruiformes: Rallidae, and tortoises (unknown family). Nymphs and larvae have been collected from Didelphimorphia: Didelphidae, Rodentia: Dasyproctidae and Muridae, and Passeriformes (several families); nymphs alone have been found on Rodentia: Heteromyidae; and larvae alone have been recovered from Coraciiformes: Momotidae (Guglielmone & Robbins 2018, Lamattina et al. 2018a). Amblyomma ovale is a frequent parasite of humans. M: Koch (1844a) F: Koch (1844a), under the name Amblyomma oblongum, a synonym of Amblyomma ovale N: Martins et al. (2010) L: Barbieri et al.

(2017) L: none Note: there are several redescriptions of Amblyomma ovale under the name Amblyomma fossum that are not included here, but Neumann (1899) and Tonelli Rondelli (1937) treat both names as separate species. The marginal groove of the male of Amblyomma ovale is usually considered complete, but Voltzit (2007) states that it is incomplete. Miller et al. (2016) present molecular evidence suggesting the presence of a cryptic taxon close to Amblyomma ovale in Panama, while Fournier et al. (2019) found molecular divergence in populations of Amblyomma ovale from northern and southern Brazil, indicating that these may represent sibling species. See also Amblyomma aureolatum.
