Abstract

A detailed description and illustrations of a new terebellid species are provided, and molecular information based on partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene are included. The new species, Neoamphitrite undevigintipessp. nov., is described from the deep sea off the eastern coast of South Korea. It is similar to Neoamphitrite groenlandica (Malmgren, 1866) in that the thorax has 19 notopodial chaetigers. However, Neoamphitrite undevigintipessp. nov. is clearly distinguishable from N. groenlandica in having the uncini of the first abdominal chaetiger arranged in a single row and in having 12 ventral shields. A taxonomic key to all known Neoamphitrite species is also included.

Highlights

The genus Neoamphitrite Hessle, 1917 is a terebellid polychaete assigned to the subfamily Terebellinae Johnston, 1846 (Fauchald 1977; Londoño-Mesa 2009)
Neoamphitrite has dichotomous branchiae with a well-developed stem and nephridial papillae with a free tube distinctly projecting from the body, while Amphitrite has filiform branchiae with a reduced stem and nephridial papillae with a fused tube retracted into the body
Type material and additional material examined were deposited at the National Institute of Biological Resources (NIBR) in Incheon, Korea and the National Marine Biodiversity Institute of Korea (MABIK) in Seocheon, Chungcheongnam-do, Korea, respectively
