从韩国一个洞穴的地下水中描述了一种新的地下伪角脚类双足动物--伪角脚亚目。Jolaei sp.11月其区别在于胸鳃的数量以及触角窦、触角1的副鞭毛和尾足3的末端物品的组合。基于核28S rRNA和组蛋白H3以及线粒体细胞色素C氧化酶亚基I和16S rRNA基因的分子系统发育分析表明，P joolaei sp.11月2018年与P.akatsukai Tomikawa&Nakano组成的林地居住在日本本州岛西部的石灰岩洞穴中。
A new subterranean species of pseudocrangonyctid amphipod, Pseudocrangonyx joolaei, is described from the groundwater of a cave in South Korea. Pseudocrangonyx joolaei sp. nov. can be distinguished from its congeners by the number of sternal gills as well as a combination of the antennal sinus, the accessory flagellum of antenna 1, and the terminal article of uropod 3. Molecular phylogenetic analyses based on nuclear 28S rRNA and histone H3, and mitochondrial cytochrome c oxidase subunit I and 16S rRNA genes revealed that P joolaei sp. nov. formed a Glade with P. akatsukai Tomikawa & Nakano, 2018 that inhabits limestone caves in the western Honshu island, Japan.
