Two new species of Prismatolaimus are described from Orange Bay, Hoste Island, Chile. Prismatolaimus novoporus sp. n. is distinguished by its females being 1.08-1.28 mm long and monovarial with a long postvulvar sac, and having a long tail (c' = 21.5-32.2); males have 11-20 supplements confined to the posterior part of the body. Prismatolaimus chilensis sp. n. is distinguished by its amphidelphic reproductive system, short tail (c' = 9.5), V = 63.4; males have 23 supplements reaching up to the neck region. A well-developed dorsal body pore behind the cardia connected with an apparently glandular organ is reported in P. novoporus sp. n. Function of the organ is unknown, and it is not a general feature in the genus. The generic diagnosis of Prismatolaimus is emended and keys to species, both females and males, are presented. The systematic position of Prismatolaimus is discussed, and it is judged to be the only genus of Prismatolaimidae. Also, it is concluded that Prismatolaimidae and Bastianidae represent two sister taxa in Araeolaimida or Leptolaimina.
从智利霍斯特岛奥兰治湾发现了两种新的棱柱线虫。新孔棱柱线虫（Prismatolaimus novoporus sp. n.）的特征在于，雌虫体长1.08 - 1.28毫米，单卵巢，具长的阴门后囊，尾部较长（c' = 21.5 - 32.2）；雄虫有11 - 20个附器，局限于身体后部。智利棱柱线虫（Prismatolaimus chilensis sp. n.）的特征在于其双子宫生殖系统、短尾（c' = 9.5）、V值为63.4；雄虫有23个附器，延伸至颈部区域。在新孔棱柱线虫中报道了一个位于贲门后方且与一个明显的腺器官相连的发育良好的背体孔。该器官的功能未知，且并非该属的普遍特征。对棱柱线虫属的分类诊断进行了修订，并给出了雌虫和雄虫的物种检索表。讨论了棱柱线虫属的系统位置，判定其为棱柱线虫科的唯一属。此外，得出结论，棱柱线虫科和巴斯蒂安线虫科在无尾感器纲或纤尾线虫亚纲中代表两个姐妹类群。
