A taxonomic review was performed on cestodes of the genus Spassky, 1947 that parasitize different species of shrews in different regions of the northern Palearctic and in the Nearctic (Alaska, USA). Information on Palearctic cestodes published in various articles is summarized. An overview of the geographical distribution of the species is also presented. Currently, the genus includes 17 species. In the European part of the Palearctic, four species of the genus are registered; in the Asian part, 13 species; and on the American continent (Seward Peninsula, Alaska, USA), two species. Descriptions, illustrations, and differential diagnoses are given for a new species of , i.e. n. sp., which was found in shrews Dobson and Laxmann on Sakhalin Island. A unique feature of the new species is irregularly alternating genital pores in the uterus series in the strobila. Amended new differential features (positioning of the uterus relative to osmoregulatory canals and alternation of genital pores) of genus diagnosis and an identification key for spp. are presented.
对寄生在北古北区和新北界(美国阿拉斯加)不同地区各种鼩鼱的 Spassky, 1947 属绦虫进行了分类学研究。总结了发表在各种文章中的有关北古北区绦虫的信息。还介绍了该物种的地理分布概述。目前,该属包括 17 个物种。在北古北区的欧洲部分,登记了四个属的物种;在亚洲部分,有 13 个物种;在美洲大陆(美国阿拉斯加的塞沃德半岛),有两个物种。对在萨哈林岛发现的一种新的 Spassky, 1947 属,即新种,进行了描述、说明和鉴别诊断。新种的一个独特特征是在子宫系列中不规则地交替出现生殖孔。提出了属诊断的修正新鉴别特征(子宫相对于渗透调节管的位置和生殖孔的交替)和 Spassky, 1947 种的鉴定钥匙。
