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 clade with P. akatsukai Tomikawa Nakano, 2018 that inhabits limestone caves in the western Honshu island, Japan.
一种新的伪钩虾科穴居性新物种——朱莱伪钩虾（Pseudocrangonyx joolaei），是从韩国一个洞穴的地下水中发现并描述的。朱莱伪钩虾新物种（Pseudocrangonyx joolaei sp. nov.）可通过其腹鳃数量以及触角窦、第一触角的副鞭、第三尾足末节的组合与同属其他物种区分开来。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，朱莱伪钩虾新物种与2018年发现的栖息于日本本州岛西部石灰岩洞穴中的赤冢伪钩虾（P. akatsukai Tomikawa Nakano）形成一个进化枝。
