Abstract
We establish a new subgenus, Filippoviella n. subgen. (Acari: Ixodidae) based on two species formerly assigned to the subgenus Exopalpiger Schulze, 1935 in the genus Ixodes Latreille, 1795. Ixodes (Filippoviella) trianguliceps Birula, 1895 is a tick species broadly distributed throughout Europe and western Siberia, the females, nymphs and larvae of which mostly feed on small mammals such as shrews and rodents. Ixodes (Filippoviella) ghilarovi Filippova & Panova, 1988 is found in the Caucasus region on rodents and shrews. The type species of this new subgenus is Ixodes trianguliceps. The major morphological differences allowing discrimination of the two species of Filippoviella n. subgen from members of the subgenus Exopalpiger are the shape of the idiosoma, shape of the basis capituli, development of palpal segment I, the suture between palpal segments II and III, development of syncoxae and chaetotaxy. We sequenced the entire mitochondrial genome of I. trianguliceps; according to our phylogeny from 10 protein-coding mitochondrial genes of 17 of the 23 Ixodes subgenera (34 spp.), I. (Filippoviella) trianguliceps is basal to the “other Ixodes” and polyphyletic with I. (Exopalpiger) fecialis Warburton & Nuttall, 1909.
硬蜱新亚属 Filippoviella n. subgen.(Acari: Ixodidae) comprising Ixodes trianguliceps Birula, 1895 and I. ghilarovi Filippova & Panova, 1988, parasites of small mammals in Europe and Asia.
我们建立了一个新的亚属,Filippoviella n. subgen.(Acari: Ixodidae) based on two species formerly assigned to the subgenus Exopalpiger Schulze, 1935 in the genus Ixodes Latreille, 1795.Ixodes (Filippoviella) trianguliceps Birula, 1895 是一种蜱虫,广泛分布于欧洲和西伯利亚西部,其雌虫、若虫和幼虫主要以鼩鼱和啮齿动物等小型哺乳动物为食。Ixodes (Filippoviella) ghilarovi Filippova & Panova, 1988 在高加索地区发现,以啮齿动物和鼩鼱为食。这个新亚属的模式种是 Ixodes trianguliceps。Filippoviella n. subgen 的两个种与 Exopalpiger 亚属成员在形态上的主要区别在于特异体的形状、基部头状体的形状、掌节 I 的发育、掌节 II 和 III 之间的缝合、合尾的发育以及混沌体。我们对 I. trianguliceps 的整个线粒体基因组进行了测序;根据我们对 23 个 Ixodes 亚属(34 种)中 17 个属的 10 个编码蛋白质的线粒体基因进行的系统发育,I. (Filippoviella) trianguliceps 属于 "其他 Ixodes 属",与 I. (Exopalpiger) fecialis Warburton & Nuttall, 1909 属于多单系。
期刊介绍:
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
