Lamispina miurai sp. nov. (Annelida: Flabelligeridae) from off Aomori, Japan

Abstract

A new species of flabelligerid polychaete, Lamispina miurai sp. nov., has been described based on material collected at a depth of 226–228 m in the Pacific Ocean, off Aomori, Japan. Lamispina miurai sp. nov. can be differentiated from other congeners by the following features: i) the body is not covered with sand or large sediment particles; ii) the lamispines are present on the chaetiger 4 and succeeding chaetigers; iii) the tip of the lamispine is curved and subdistally serrated; iv) the cephalic cage is formed by chaetigers 1–3; and v) the length of the cephalic cage is twice as long as the body width.
