A new species of Phyllocomus Grube, 1878 from the Yellow Sea, China (Annelida, Ampharetidae)

Abstract

A new species of the ampharetid genus Phyllocomus, P. chinensis sp. n., is described based on material from the Yellow Sea. The new species is distinguished from the known species of this genus by having two thoracic regions, with segments of the anterior region (up to thoracic chaetiger 10) approximately half as long as those of the posterior region, neuropodia of the anterior region are large while those of the posterior region become gradually smaller, thoracic neuropodia without dorsal cirrus, and abdominal neuropodia with a papillary dorsal cirrus. A key to all species of Phyllocomus is given.
