A New Species, Lamispina ammophila sp. nov. (Annelida: Flabelligeridae), from Shimoda, Japan

Abstract

A new species of flabelligerid polychaete, Lamispina ammophila sp. nov., is described from off the coast of Shimoda, Japan. The species can be discriminated from the other congeners by the following features: i) dorsal region of body being adhered to by sediment particles, ii) lamispines without accessory tooth, present from chaetiger 4 and succeeding chaetigers, and iii) cephalic cage 1.5–2.0 times as long as body width. A partial mitochondrial cytochrome c oxidase subunit I (COI) gene sequence from the paratype is provided as a DNA barcode for the new species.
