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。
