Amblyomma testudinarium Koch 1844

122. Amblyomma testudinarium Koch, 1844a.

An Oriental species with some records from the Palearctic Region and even a few from the Australasian Region, whose adults are usually found on Artiodactyla: Suidae. All parasitic stages of Amblyomma testudinarium have been collected from Mammalia (several orders), and Squamata: Varanidae; adult ticks alone have been recovered from Testudines: Emydidae and Testudinidae, and Squamata: Pythonidae; immature stages have been found on Charadriiformes: Scolopacidae, Galliformes: Phasianidae, Passeriformes: Corvidae, Anura: Microhylidae, and Squamata: Colubridae and Viperidae. Amblyomma testudinarium is a very frequent parasite of humans.

Note: Yamaguti et al. (1971) questioned reports of larvae of Amblyomma testudinarium collected from anuran hosts in Sugimoto (1937a, b); however, the larval description of this species in Sugimoto (1937c) was based on specimens hatched from eggs laid by a female Amblyomma testudinarium collected on a buffalo, and this description is therefore treated here as valid. The larva of Amblyomma sp. 1 in Kadarsan (1971) is most probably Amblyomma testudinarium, but that author believes that comparison with laboratory-reared material is needed in order to confirm the specific diagnosis. Chao et al. (2017) found molecular differences between Taiwan and Japanese specimens of Amblyomma testudinarium and those from Thailand, indicating that such samples may represent different taxa, a hypothesis supported by Guglielmone et al. (2017).
