Abstract

A new species of amphinomid polychaete, Benthoscolexseisuiaesp. 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.seisuiaesp. n. is provided for reliable species identification in the future.
