Only a few aspects of the biology of Amblyomma parvitarsum Neumann are known. Adults of this hard tick species are parasites of South American camelids in the Andean plateau of Argentina, Bolivia, Peru and Chile and also in the Argentine Patagonia, but they have been also rarely found on other artyodactils and two species of birds. The larva has been collected from reptiles in northern Chile, whereas the hosts for the nymph remain unknown. On nine localities included within Altitude Tropical and Perarid Mediterranean ecoregions in northern Chile, we analyzed 237 reptiles, 285 birds, 624 rodents and 52 camelids for infestation with A. parvitarsum to calculate seasonal prevalence of this tick. We also reviewed the literature of this tick and three entomological collections for obtaining and summarizing all the information to date about this tick. None of the analyzed birds and rodents were parasitized with A. parvitarsum; however, seven over a total of ten reptile species that we caught were infested with the larva. In the camelid species Lama glama and Vicugna pacos we collected adult specimens of this tick. Larval prevalence was higher during fall (75 %) in Liolaemus pleopholis in the Altitude Tropical ecoregion. We also collected adult specimens of A. parvitarsum from camelid manure heaps during summer in Salar de Surire and Llullaillaco localities. Additionally, we also reviewed the literature of this tick and examined specimens in three entomological collections for obtaining and summarizing all the information to date about this tick. By this study, nine localities and seven new hosts are added for A. parvitarsum and we confirm reptiles as specific hosts of this tick larva.
仅有少数关于 Amblyomma parvitarsum Neumann 的生物学方面的知识为人所知。这种硬蜱的成蜱是安第斯高原上阿根廷、玻利维亚、秘鲁和智利的南美驼马的寄生虫，也存在于阿根廷巴塔哥尼亚地区，还偶尔出现在其他偶蹄目动物和两种鸟类身上。幼虫在智利北部的爬行动物身上被采集到，而若虫的宿主尚不清楚。在智利北部的热带高地和地中海边缘地区的九个地点，我们分析了 237 只爬行动物、285 只鸟类、624 只啮齿动物和 52 只骆驼，以计算这种蜱的季节性流行率。我们还查阅了有关这种蜱的文献和三个昆虫学收藏，以获取并总结迄今为止有关这种蜱的所有信息。我们分析的鸟类和啮齿动物均未寄生 A. parvitarsum；然而，我们捕获的十种爬行动物中，有七种被幼虫寄生。在骆驼科的羊驼属和小羊驼属中，我们采集到了这种蜱的成虫标本。在热带高地生态区的 Liolaemus pleopholis 中，秋末（75%）幼虫的流行率更高。我们还在 Salar de Surire 和 Llullaillaco 两地的骆驼粪便堆中采集到 A. parvitarsum 的成虫标本。此外，我们还查阅了有关这种蜱的文献，并在三个昆虫学收藏中检查了标本，以获取并总结迄今为止有关这种蜱的所有信息。通过这项研究，为 A. parvitarsum 增加了九个地点和七个新的宿主，并确认爬行动物是这种蜱幼虫的特定宿主。
