In a recent study on ixodid bat ticks from Eurasia, a high genetic difference was found between Ixodes vespertilionis from Europe and Vietnam. Accordingly, it was proposed that I. vespertilionis is a species complex, with at least one additional, hitherto undescribed species. The aim of the present study was to investigate the morphology of bat ticks from Vietnam and to assess their taxonomic status in comparison with those collected in Europe.
Ixodid bat ticks (two females and two nymphs) collected from the pomona leaf-nosed bat (Hipposideros pomona) (Hipposideridae) and intermediate horseshoe bat (Rhinolophus affinis) (Rhinolophidae) in Vietnam showed major morphological differences from European isolates of I. vespertilionis, including the shape of the scutum, the enclosure and shape of porose areas, the presence of a caudo-lateral collar-like ridge ventrally on the basis capituli, polytrich coxae with short setae, and grouped (non-linear) arrangement of anterior pit sensillae in Haller's organ.
In this study the female and the nymph of an ixodid bat tick species from Vietnam are described for the first time. The genetic and morphological differences between I. vespertilionis Koch, 1844 and these bat ticks from Vietnam justify the status of the latter as a distinct species, Ixodes collaris Hornok n. sp.
在最近一项关于欧亚大陆硬蜱科蝙蝠蜱的研究中，发现欧洲和越南的食虫蝙蝠硬蜱（Ixodes vespertilionis）之间存在高度遗传差异。因此，有人提出食虫蝙蝠硬蜱是一个物种复合体，至少还存在一个迄今未被描述的物种。本研究的目的是调查越南蝙蝠蜱的形态，并与在欧洲采集的蝙蝠蜱进行比较，以评估它们的分类地位。
从越南的棕果蝠（Hipposideros pomona）（菊头蝠科）和中蹄蝠（Rhinolophus affinis）（蹄蝠科）采集到的硬蜱科蝙蝠蜱（两只雌性和两只若虫）与欧洲的食虫蝙蝠硬蜱分离株在形态上存在主要差异，包括盾板形状、多孔区的包围和形状、假头基部腹侧有一条尾侧领状脊、具短刚毛的多毛基节以及哈勒氏器中前坑感受器的成组（非线性）排列。
在本研究中，首次描述了来自越南的一种硬蜱科蝙蝠蜱的雌性和若虫。1844年的食虫蝙蝠硬蜱（Ixodes vespertilionis Koch）与这些来自越南的蝙蝠蜱在遗传和形态上的差异证明了后者作为一个独特物种——领状硬蜱（Ixodes collaris Hornok）新种的地位。
