Abstract

An integrative description of a newly discovered Spitsbergen population of Diphascon tenue Thulin, 1928 was undertaken using high quality light microscopy, scanning electron microscopy and methods of molecular taxonomy. Phylogenetic analyses indicated the relationships of this species within the subfamily Itaquasconinae Bartoš in Rudescu, 1964 (the family Hypsibiidae Pilato, 1969). Arctodiphascon gen. nov. is erected with two species, A. tenue, comb. nov. and A. wuyingensis (Sun et al., 2020), comb. nov. Following the results of the phylogenetic molecular and morphological analysis, Adropion greveni (Dastych, 1984) and A. mauccii (Dastych et McInnes, 1996) are transferred to the genus Diphascon Plate, 1888 as D. greveni Dastych, 1984, stat. resurr. and D. mauccii Dastych et McInnes, 1996, stat. resurr. Following the results of the phylogenetic molecular and morphological analyses, the generic name Meplitumen Lisi et al., 2019, syn. nov. is recognised as synonymous to Platicrista Pilato, 1987. An emended diagnosis for the genus Astatumen Pilato, 1997 is given. The distribution of morphological characters within the superfamily Hypsibioidea is analysed and their taxonomic significance is discussed. A new phylogenetic tree of Hypsibioidea based on molecular data is presented. The subfamilies Itaquasconinae and Pilatobiinae Bertolani et al., 2014 are raised to family rank, as Itaquasconidae and Pilatobiidae (status promotus). The subfamily Diphasconinae Dastych, 1992 is transferred to the Hypsibiidae, as a sister group to the subfamily Hypsibiinae Pilato, 1969.

有些有下降，有些没有，但我们能相信吗?缓步动物(缓步动物:真缓步动物)的再调查与超科系统发育和分类的讨论

利用高质量光学显微镜、扫描电镜和分子分类学方法对新发现的Spitsbergen Diphascon tenue Thulin, 1928种群进行了综合描述。系统发育分析表明，该物种属于1964年在鲁德斯库发现的Itaquasconinae Bartoš i亚科(Pilato hysibiidae, 1969)。双翅蚁属11 .有两种直立，蜂尾，梳状。11 . and A. wuyingensis (Sun et, 2020)，梳子。11 .根据系统发育分子和形态分析的结果，Adropion greveni (Dastych, 1984)和A. mauccii (Dastych et McInnes, 1996)被转移到Diphascon Plate属，1888，作为D. greveni Dastych, 1984, statr . resurr。D. mauccii Dastych et McInnes, 1996, stat. resurrection。根据系统发育分子和形态分析结果，属名Meplitumen Lisi et al.， 2019, syn. 11 .被认为与Platicrista Pilato, 1987同义。一个修正诊断属Astatumen Pilato, 1997年给出。分析了该超科的形态特征分布，并讨论了其分类学意义。提出了一种新的基于分子数据的假说生物的系统发育树。将Itaquasconinae亚科和Pilatobiinae Bertolani et al.， 2014提升为Itaquasconidae和Pilatobiidae(地位提升)。1992年的Diphasconinae Dastych亚科被转移到Hypsibiidae，作为1969年的Hypsibiinae Pilato亚科的姐妹群。

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.
