Abstract

A new species of tardigrade from the genus Hypsibius Ehrenberg, 1848 is described from the bottom sediments of a small lake in the central part of Scandinavian Peninsula (Sweden), using an integrative approach, i.e. morphological techniques (light and scanning electron microscopy) combined with a molecular analysis (18S rRNA, 28S rRNA, ITS-2 and COI markers). Hypsibius repentinus sp. nov. belongs to the Hypsibius dujardini species–group and differs from the most similar species of this group in having a second macroplacoid with a definite constriction and in some other morphometric characters. Morphological diagnosis for the Hypsibius dujardini species–group is proposed, and its composition is discussed.

瑞典Hypsibius reveninus sp.nov.（Eucardigrada:Hypsibiidae）的综合描述

利用形态学技术(光镜和扫描电镜)和分子分析(18S rRNA、28S rRNA、ITS-2和COI标记)相结合的综合方法，在斯堪的纳维亚半岛(瑞典)中部一个小湖泊的底部沉积物中描述了一种新的水熊虫属Hypsibius Ehrenberg, 1848。海参属海参属(Hypsibius reusiinus sp. nov.)，与该属最相似的种群不同之处在于其有一个具有明确收缩的第二大类肌和其他一些形态特征。提出了杜氏水蚤种群的形态诊断，并对其组成进行了讨论。

期刊介绍： Zoosystematica Rossica is an international journal for publication of papers on any aspects of systematic zoology, in all groups of animals, both extant and fossil, from all over the World. The journal is published in English and focuses on the descriptions of new taxa, revisions and reviews, nomenclature, theories and methods of taxonomy and phylogeny, interesting new faunal records, catalogues and checklists, identification keys, phylogenetic relationships and zoogeography. Faunistic articles are published in a limited way and only if they contain new records for large geographical regions and are important for zoogeography or taxonomy.
