Abstract

The female of Argas (Persicargas) keiransi Estrada-Peña, Venzal & González-Acuña (Acari: Argasidae) is described from specimens collected in the type locality in Chile. The female has a unique combination of characters in the dorsal cuticle and in the number and pattern of ventrolateral setae in the basis capituli. Additional features on tarsus I chaetotaxy and dorsal plate are provided for the larva of the species, as observed on flat specimens derived from engorged females collected in the type locality. Keys for the larvae of the New World Persicargas are provided as well as illustrations for prominent characters in hypostome and posterolateral setae. The mitochondrial 16S rDNA sequence of A. keiransi has been obtained, and an analysis of the phylogenetic relationships with other ticks is included. Phylogenetic analysis provides support for a Persicargas grouping of species, separated from species in Argas.

摘要

基于在智利模式产地采集的标本，对基氏锐缘蜱（波斯锐缘蜱）（Argas (Persicargas) keiransi Estrada-Peña, Venzal & González-Acuña）雌蜱进行了描述（蜱螨亚纲：锐缘蜱科）。该雌蜱在背角质层以及假头基部腹侧刚毛的数量和排列方式上具有独特的特征组合。文中还给出了该物种幼虫在跗节I的毛序以及背板的其他特征，这些特征是在模式产地采集的饱血雌蜱所产扁平标本上观察到的。文中提供了新大陆波斯锐缘蜱幼虫的检索表，以及口下板和后外侧刚毛显著特征的图示。已获得基氏锐缘蜱的线粒体16S rDNA序列，并对其与其他蜱类的系统发育关系进行了分析。系统发育分析为波斯锐缘蜱物种群的划分提供了支持，该物种群与锐缘蜱属的物种相分离。
