    Soft ticks (Argasidae) of the subgenus Pavlovskyella Pospelova-Shtrom are worldwide distributed parasites of medical importance. However, the systematics of the subgenus are currently under debate because genetic data shows that the group is paraphyletic. Meanwhile, species of Pavlovskyella continue to be discovered. In this study a novel species of the subgenus is described from specimens collected on a fox in central Chile. The larva of this new species ... ...点击完成人机验证后继续浏览

    软蜱(Argasidae)亚属Pavlovskyella Pospelova-Shtrom是具有医学重要性的全球分布寄生虫。然而,由于基因数据表明该群体为旁系群,因此亚属的分类目前存在争议。与此同时,Pavlovskyella物种仍在不断被发现。在这项研究中,描述了一个从智利中部狐狸身上采集到的新种软蜱。这种新物种的幼虫与其他Pavlovskyella物种的区别在于以下特征组合:近梨形背板;15对刚毛(7对前侧、3对中央和5对后侧),以及下唇远端三分之一处有齿状结构。该物种的若虫和成虫缺乏颊部、眼睛或侧面隆起结构,但具有背腹沟,并且在第I至III足节跗段上出现小丘状突起。此外,在股骨褶皱的远端部分出现了无毛体壁斑块。基于线粒体基因组进行的系统发育分析表明,Ornithodoros (Pavlovskyella) brasiliensis Aragão、Ornithodoros (Pavlovskyella) furcosus Neumann、Ornithodoros (Pavlovskyella) improvisus Muñoz-Leal & Venzal 和 Ornithodoros (Pavlovskyella) rostratus Aragão 形成一个单系群。有趣的是,基于18S-28S rDNA序列的系统发育分析显示南美地区的Pavlovskyella物种是旁系群,正如之前的研究所展示的一样。将新热带地区亚属中的物种添加到系统发育分析中可能有助于解决这种旁系现象。此外,这是在南美洲描述的第五个Pavlovskyella物种,并且是在智利发现的第二个物种。
