A new species, Ornithodoros microlophi (Acari: Argasidae), belonging to the subgenus Alectorobius is described from larvae collected on the lizards Microlophus atacamensis (Donoso-Barros, 1966) and Microlophus quadrivittatus (Tschudi, 1845) (Squamata: Tropiduridae) in continental and insular localities from northern Chile. Larvae of O. microlophi can be distinguished from other Neotropical species of the genus Ornithodoros by a combination of the following characters, namely 10 pairs of ventral setae, venter with 6 pairs of sternal setae, dorsal plate pyriform, 19-21 pairs of dorsal setae (typically 20), 13 pairs are dorsolateral and 7 pairs are central, and hypostome with dental formula 4/4 in medial portion and apex pointed. Phylogenetic analysis of 16S rDNA sequences suggests that O. microlophi represents an independent lineage within Neotropical species of the Argasidae.
一种新的物种，即 Ornithodoros microlophi（蜱螨目：软蜱科），隶属于 Alectorobius 亚属，是从智利北部大陆和岛屿地区采集的 Microlophus atacamensis（Donoso-Barros，1966）和 Microlophus quadrivittatus（Tschudi，1845）（有鳞目：鬣蜥科）蜥蜴幼虫中分离出来的。Ornithodoros microlophi 的幼虫可通过以下特征组合与其他新世界的 Ornithodoros 属物种区分开来，即 10 对腹侧刚毛、腹板有 6 对胸侧板刚毛、背板梨形、19-21 对背侧板刚毛（通常为 20 对）、13 对为背侧板和 7 对为中央侧板，以及口下片在中部和尖端具有 4/4 的齿式。16S rDNA 序列的系统发育分析表明，Ornithodoros microlophi 代表 Argasidae 属的新世界种中的一个独立谱系。
