The work was carries our from the standpoint of the morphological conception of species. Vast collections of the Zoological Institute of the Russian Academy of Science testify to the existence of hiatuses in both genera and subgenera of Palearctic ixodids at all active phases of their ontogenesis. The fact that the subgenera of Palearctic genera have been well studies is notes, and composition of the subgenera is presented. The question of a taxonomic intercalary rank "species complex" is considered in detail in the context of the coevolution between some complexes of closely related species of ixodid ticks and some closely related species (genospecies, strains) of pathogens. The question of the taxonomic rank "species complex" in ixodid ticks as a phyletic species association is postulated on the basis of comparative ontogenetic data. Nomenclature status of the intercalary association "species complex" is specified in conformity with the fourth edition of the International Code of Zoological Nomenclature. Species composition of most studied complexes is presented. Some variants of morphological differentiation between species complexes within subgenus are considered. Significance of the taxonomic concept "species complex" for zoological. parasitological, and medical aspects of the ixodid ticks study was evaluated. Prognostic significance of the rank "species complex" for the study of the relationships between ixodid ticks and pathogens is discussed.
这项工作是从物种的形态学概念角度开展的。俄罗斯科学院动物研究所的大量藏品证明，古北区硬蜱科在其个体发育的所有活跃阶段，属和亚属中都存在间断。文中指出，古北区属的亚属已得到充分研究，并列出了亚属的组成。在一些近缘硬蜱物种复合体与一些近缘病原体物种（基因种、菌株）之间的协同进化背景下，详细探讨了分类学中间等级“物种复合体”的问题。基于比较个体发育数据，假定硬蜱中“物种复合体”这一分类等级为一种系统发育物种关联。根据《国际动物命名法规》第四版，明确了中间关联“物种复合体”的命名地位。列出了大多数研究复合体的物种组成。考虑了亚属内物种复合体之间形态分化的一些变体。评估了“物种复合体”这一分类概念在硬蜱动物学、寄生虫学和医学研究方面的意义。讨论了“物种复合体”等级在研究硬蜱与病原体之间关系方面的预测意义。
