本文报道了多形环节动物一新种，Bathykermadeca thanatos sp. nov.根据从菲律宾海南海-松涛海沟4974米深处的沉没鲸骨中采集的标本描述。该地点的鲸目动物尸体群落超过了迄今报告的最深记录。该新种与该属其他成员的区别在于：1）只有一种脉毛类; 2）齿无锯齿，向内生长; 3）中触角伸出额丝顶端; 4）第12-15节有肾乳头; 5）每个副足节内约有50个背毛类。
A new species of polynoid annelids, Bathykermadeca thanatos sp. nov., is described based on specimens collected from sunken whale bones in the Nansei-Shoto Trench in the Philippine Sea at a depth of 4974 m. The cetacean-carcass community at the site exceeds the deepest record reported to date. This new species can be distinguished from other members of the genus by the following features: i) there is only one type of neurochaetae, ii) the teeth lack serration and grow inwardly, iii) median antenna extends beyond the tip of frontal filament, iv) nephridial papillae are present in segments 12–15, and v) there are about 50 notochaetae in each parapodium.
