Abstract

A new species of amphinomid polychaete, , 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 from Japan. A partial mitochondrial cytochrome oxidase subunit I gene sequence from the holotype of is provided for reliable species identification in the future.

摘要

一种新的矶沙蚕科多毛纲动物，从日本熊野海487 - 596米深处被描述。该物种与其同属物种的区别在于以下特征：i）触须长度是侧触角的1.8倍；ii）鳃未延伸到背刚毛尖端。这是该物种在日本的首次记录。提供了该物种模式标本的部分线粒体细胞色素氧化酶亚基I基因序列，以便未来进行可靠的物种鉴定。
