Lepidonema magnum Morffe García, 2010 (Nematoda: Oxyuridomorpha: Hystrignathidae) is redescribed and illustrated with the aid of SEM. New features of the cephalic end and genital tract of the females were observed. New locality records are given. The phylogenetic position of the species is inferred on the basis of the D2-D3 segment of the 28S LSU rDNA and 18S SSU rDNA. L. magnum forms a monophyletic clade formed by other hystrignathids: Coynema poeyi (Coy, García Álvarez, 1993), two species of Longior Travassos Kloss, 1958 and two Hystrignathus Leidy, 1850.
大鳞细颈线虫Lepidonema magnum Morffe García,2010(线虫纲:尖尾线虫目:异唇线虫科)借助扫描电子显微镜进行了重新描述和图示。观察到了雌性头部末端和生殖道的新特征。给出了新的产地记录。基于28S LSU rDNA和18S SSU rDNA的D2-D3片段推断了该物种的系统发育位置。大鳞细颈线虫形成了一个单系类群,该类群由其他异唇线虫组成:波氏科伊线虫Coynema poeyi(Coy,García Álvarez,1993)、1958年的特拉瓦索斯长体线虫属的两个物种以及1850年的两个异唇线虫属物种。
