本文记述了一新种，即细穗底栖蚤（Benthoscolexseisuiaesp. n.）描述于日本熊野海，水深487-596米。该物种与其同类的区别在于以下特征：i）触须是侧触角的1.8倍; ii）鳃不能达到背毛纲的顶端。这是日本首次记录的底栖动物。一个来自B正模的线粒体细胞色素c氧化酶亚基I基因的部分序列。seisuiae sp. n.为今后可靠的物种鉴定提供了依据。
A new species of amphinomid polychaete, Benthoscolex seisuiae sp. n., is described from the Sea of Kumano, Japan, from depths of 487–596 m. The species is distinguishable from its congeners by the following features: i) palps 1.8 times as long as lateral antennae; ii) branchiae do not reach to the tip of the notochaetae. This is the first record of Benthoscolex from Japan. A partial mitochondrial cytochrome c oxidase subunit I gene sequence from the holotype of B. seisuiae sp. n. is provided for reliable species identification in the future.
