Abstract

We describe Tenuibiotus yeliseii sp. nov., a new tardigrade species from Svalbard, using morphological and morphometric analyses conducted with the use of light and scanning electron microscopy, as well as genetic analyses based on four molecular markers (three nuclear, 18S rRNA, 28S rRNA, ITS-2, and one mitochondrial, COI). A phylogenetic analysis of the genus Tenuibiotus Pilato et Lisi, 2011 is conducted using new data. In addition, the taxonomic significance of gibbosities on leg IV as a key character for species identification in Tenuibiotus is discussed. A key to the species of Tenuibiotus is proposed.

Tenuibiotus yeliseii sp.

我们利用光显微镜和扫描电子显微镜进行了形态学和形态计量学分析，并基于四个分子标记（三个核标记，18S rRNA、28S rRNA、ITS-2，以及一个线粒体标记，COI）进行了遗传学分析，从而描述了斯瓦尔巴群岛的新种--Tenuibiotus yeliseii sp.nov.。利用新数据对 Tenuibiotus 属 Pilato et Lisi（2011 年）进行了系统发育分析。此外，还讨论了作为 Tenuibiotus 物种鉴定关键特征的腿胫 IV 的分类学意义。提出了 Tenuibiotus 的物种检索表。

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.
