最近基于16 S rRNA基因的Myxinidae的系统发育分析导致Paramyxine与Eptatretus同步。这造成了Paramyxine fernholmi与Eptatretus fernholmi和Paramyxine wisneri与Eptatretus wisneri的同名。为了解决这个命名的困境，我们做了一个更广泛的Myxinidae的系统发育评估和检查的家庭的命名。我们使用了75个序列（其中37个新的本研究）的561 bp片段的16 S rRNA基因，代表33个物种，和72个序列（其中37个新的本研究）的687 bp片段的细胞色素c氧化酶亚基I（COI）基因，代表23个物种，重建Myxinidae的生殖。Myxinininae亚科的单系性，传统上的特点是有一对外部鳃开口，被拒绝（0.50贝叶斯后验概率）的16 S分析，但支持的COI和COI+16 S分析（0.99和0.81 Bpp，分别）。Eptatretinae亚科的单系性，其特征是有几对外部鳃开口，不支持的16 S分析和拒绝的COI和COI+16 S分析，由于放置Eptatretuslopheliae作为最早的分支的Myxinidae（分别为0.71和0.57 Bpp）。Eptatretus lopheliae和Eptatretus rubicundus形成一个单系群，并被分配到一个新的属，Rubicundus，其特征是存在细长的管状体和红色着色。提出了一个新的单型亚科--Rubicundinae。证实了副粘虫属和方粘虫属与粘虫属的异名。E. fernholmi被重新命名为Eptatretus luzonicus。Eptatretus wisneri改名为Eptatretus bobwisneri。Petromyzon cirrhatus Forster，1801，Homea banksii Fleming，1822和Bdellostoma forsteri M€ 1836是同义词，但没有模式标本存在。在保留现有用途的前提下，将卷须岩吸鳅（Petromyzoncirrhatus）定为粘盲鳗属的模式种。Gastrobranchus dombeyi Shaw，1804优先于其他名称的智利myxinids。斯氏蛭形吸虫（Bdellostoma stoutii）为刺孔绦虫（Polistotrema Gill）的模式种。确认了西大西洋Myxine limosa区别于东大西洋Myxine dumososa的有效性。
A recent phylogenetic analysis of the Myxinidae based on the 16S rRNA gene resulted in synonymization of Paramyxine with Eptatretus. This created homonymy of Paramyxine fernholmi with Eptatretus fernholmi and Paramyxine wisneri with Eptatretus wisneri. In order to resolve this nomenclatural dilemma, we made a more extensive phylogenetic assessment of the Myxinidae and examined the nomenclature of the family. We used 75 sequences (37 of which new for this study) of a 561 bp fragment of the 16S rRNA gene, representing 33 species, and 72 sequences (37 of which new for this study) of a 687 bp fragment of the cytochrome c oxidase subunit I (COI) gene, representing 23 species, to reconstruct the phylogeny of Myxinidae. The monophyly of the subfamily Myxininae, traditionally characterized by having a single pair of external gill openings, was rejected (0.50 Bayesian posterior probability) by the 16S analysis, but supported by the COI and combined COI+16S analyses (0.99 and 0.81 Bpp, respectively). The monophyly of the subfamily Eptatretinae, characterized by having several pairs of external gill openings, was not supported by the 16S analysis and rejected by the COI and combined COI+16S analysis due to the placement of Eptatretus lopheliae as the earliest branch of Myxinidae (0.71 and 0.57 Bpp, respectively). Eptatretus lopheliae and Eptatretus rubicundus formed a monophyletic group and were allocated to a new genus, Rubicundus, characterized by the presence of an elongated tubular nostril and reddish coloration. A new monotypic subfamily, Rubicundinae, was proposed for Rubicundus. The synonymy of the genera Paramyxine and Quadratus with Eptatretus was confirmed. E. fernholmi is renamed Eptatretus luzonicus. Eptatretus wisneri was renamed Eptatretus bobwisneri. Petromyzon cirrhatus Forster, 1801, Homea banksii Fleming, 1822, and Bdellostoma forsteri M€ 1836 are synonyms, but no type specimens are known to exist. Petromyzon cirrhatus was designated as type species of Eptatretus, conserving present usage. Gastrobranchus dombeyi Shaw, 1804 has priority over other names for Chilean myxinids. Bdellostoma stoutii was designated as type species of Polistotrema Gill. The validity of the Western Atlantic Myxine limosa as distinct from the Eastern Atlantic Myxine glutinosa was confirmed.
