sp. nov. is described for the seamounts near Desventuradas Islands, in the intersection of the Salas & Gómez and Nazca Ridges, Chile. Specimens of the new species were collected in the summit (∼200 m depth) of one seamount and observed by ROV at two nearby ones. This species is characterized by the presence of distinct carinae on the thoracic sternites 6 and 7. Furthermore, it is not related with any species from the continental shelf nor the slope of America, while it is closely related to species of from French Polynesia and the West-Pacific Ocean (i.e., and ). In situ observations indicate that the species lives among the tentacles of ceriantarid anemones and preys on small crustaceans. The discovery of this new species adds to the knowledge of the highly endemic benthic fauna of seamounts of the newly created Nazca-Desventuradas Marine Park, emphasizing the relevance of this area for marine conservation.
新物种被描述于智利萨拉与戈麦斯海岭和纳斯卡海岭交汇处的德斯温图拉达斯群岛附近的海山。新物种的标本是在一座海山的山顶（约200米深度）采集的，并通过遥控潜水器在附近的两座海山上进行了观察。该物种的特征是在胸节腹板6和7上有明显的隆线。此外，它与美洲大陆架或陆坡的任何物种都没有关系，而与法属波利尼西亚和西太平洋的物种（即 和 ）关系密切。现场观察表明，该物种生活在角海葵的触手之间，以小型甲壳类动物为食。这一新物种的发现增加了对新创建的纳斯卡 - 德斯温图拉达斯海洋公园海山高度特有底栖动物群的了解，强调了该地区对海洋保护的重要性。
