We describe sp. nov. (Ostracoda: Podocopida: Paradoxostomatidae) obtained from the body surface of the feather star A. H. Clark, 1908 (Crinoidea: Comatulida: Antedonidae). This is the first report of Ostracoda associated with Crinoidea. None of the highly specialized appendages and/or carapace that are related to a commensal lifestyle were observed in . sp. nov. Therefore, the relationship between . sp. nov. and must be transient rather than obligatory. However, . sp. nov. has a more developed hook-like distal claw on the antenna in comparison with four previously known species. The relatively well-developed distal claw of the antenna in . sp. nov. should indicate its intimate association with feather stars, though the feeding habit is still unknown.
我们描述了一种新种（介形纲：豆形目： paradoxostomatidae），它是从 1908 年的羽毛星 A. H. 克拉克（crinoidea：comatulida：antedonidae）的体表获得的。这是首次报道与海百合目相关的介形纲动物。在新种中没有观察到与共生生活方式相关的高度专业化的附肢和/或甲壳。因此，新种与的关系必须是暂时的，而不是强制性的。然而，与以前已知的四个物种相比，新种的触角上有一个更发达的钩状远端爪。尽管其摄食习性尚不清楚，但新种触角上相对发达的远端爪表明它与羽毛星有密切的联系。
