副关节总目一新科-副关节总目。11月-日的建立是为了容纳两个没有科分类的属（Paratanaoidea incertae sedis），即Armatognathia Kudinova-Pasternak， 1987和paratarrurella Lang， 1971。从大西洋和太平洋不同深海地区采集的材料中描述了7个新种和2个新种。副arthrorella的模式种- P. caudata (Kudinova-Pasternak, 1965) -基于该模式进行了重新描述。Cheliasetosatanais Larsen和Araujo-Silva， 2014最初归类于Colletteidae的属与parararthrurella同义，而Arthrura shiinoi Kudinova-Pasternak， 1973被转移到Armatognathia。给出了Armatognathia和副关节炎属的修正诊断。在主成分分析的支持下，选择性状来区分和定义两个属。COI和18S数据集的分子系统发育分析支持了新家族的命名。对目前包括在新科中的所有物种的分布进行了可视化，并分析了它们的水深分布。
A new family of paratanaoidean Tanaidacea - Paranarthrurellidae fam. nov. - is erected to accommodate two genera without family classification (Paratanaoidea incertae sedis), namely Armatognathia Kudinova-Pasternak, 1987 and Paranarthrurella Lang, 1971. Seven new species of Paranarthrurella and two of Armatognathia are described from material taken in different deep-sea areas of the Atlantic and Pacific oceans. The type species of Paranarthrurella - P. caudata (Kudinova-Pasternak, 1965) - is redescribed based on the paratype. The genus Cheliasetosatanais Larsen and Araujo-Silva, 2014 originally classified within Colletteidae is synonymised with Paranarthrurella, and Arthrura shiinoi Kudinova-Pasternak, 1973 is transferred to Armatognathia. Amended diagnoses of Armatognathia and Paranarthrurella genera are given. Choosing characters for distinguishing and defining both genera was supported by Principal Component Analysis. Designation of the new family is supported by molecular phylogenetic analysis of COI and 18S datasets. The distribution of all species currently included in the new family was visualised and their bathymetric distribution analysed.
