自 1994 年首次对 Notothenioidei 亚目进行分子研究以来，许多系统发育研究已发表。其中，那些拥有足够数量类群的人都认为，目前定义的Nototheniidae是单系的，其中包括Channichthyidae、Artedidraconidae、BatHydraconidae和Harpagiferidae。最近包括更多类群的研究证实了这一点，但在这些研究中，核标记的数量或所包含的类群的数量仍然很低。我们获得了涵盖大多数nototheniid属的大样本序列，其中包含先前描述的其他样本的5个标记（COI、Rhodopsin Retrogene、Pkd1、HECW2和SSRP1）以及一个以前从未在系统发育推断中使用过的核标记（PPM1d）。核编码基因的联合分析拓扑，以及SSRP1（非编码）的拓扑和所有标记的联合分析都支持Nototheniidae的并系类群，Notothenia属（包括Paranotothenia）是Channichthyidae、Artedidraconidae、BatHydraconidae和Harpagiferidae分支的姐妹群，Gobionotothen属是两者的姐妹群。与之前的研究一样，Trematomus、Lepidonotothen 和 Patagonotothen 形成一个进化枝，其中还包括 Indonototheniacyanobrancha。 Pleuragramma antarctica、Dissostichus 种和 Aethotaxis mitopteryx 的位置仍然不稳定，并且依赖于标记和分析。因此，我们建议将南极高地分支的四个科纳入 Nototheniidae 中，并将其转化为亚科。我们将 Paranotothenia magellanica 转移到 Notothenia 属，称为 Notothenia magellanica。 (C) 2012 Elsevier B.V. 保留所有权利。
Since the first molecular study of the suborder Notothenioidei in 1994, many phylogenetic studies have been published. Among these, those with a sufficient number of taxa have all suggested that the Nototheniidae, as currently defined, is monophyletic only with the inclusion of the Channichthyidae, Artedidraconidae, Bathydraconidae and Harpagiferidae. This is corroborated by more recent studies including more taxa, but in these studies either the number of nuclear markers or the number of taxa included remained low. We obtained sequences for a large sampling covering most nototheniid genera for five markers described previously for other samplings (COI, Rhodopsin retrogene, Pkd1, HECW2, and SSRP1) and one nuclear marker never used before in phylogenetic inference (PPM1d). The topology for the combined analysis of the nuclear coding genes, as well as the topology for SSRP1 (non-coding) and the combined analysis for all markers all support the paraphyly of Nototheniidae, the genus Notothenia (including Paranotothenia) is the sister group of the clade Channichthyidae, Artedidraconidae, Bathydraconidae and Harpagiferidae, and genus Gobionotothen is a sister group to both. As in previous studies, Trematomus, Lepidonotothen and Patagonotothen form a clade that also includes Indonotothenia cyanobrancha. The position of Pleuragramma antarctica, Dissostichus species and Aethotaxis mitopteryx remains unstable and dependant on markers and analyses.We therefore propose the inclusion of the four families of the High Antarctic clade in the Nototheniidae, and their transformation into subfamilies. We transfer Paranotothenia magellanica to the genus Notothenia, as Notothenia magellanica. (C) 2012 Elsevier B.V. All rights reserved.
