Аннотация

A new species of nephtyid polychaete habiting from the sublittoral to the continental slope (depth 14–500 m) of the Northwest Atlantic is described. The most significant characters of adults are: interramal parts of the preacicular lobes are wrapped around the acicular lobes; interramal parts of the neuropodial postacicular lobes and interramal parts of the postacicular rows of neurochaetae wrapped around the acicular and preacicular lobes; interramal parts of the postacicular rows of notochaetae wrapped around the acicular and preacicular lobes and covered by the bases of the notopodial cirri. Comparison with other species of the genus is provided.
