Abstract

A new species of the orbiniid genus Phylo Kinberg, 1866, P. heterochaetussp. nov., is described based on material collected from the northern Yellow Sea, China. This is the thirteenth species in Phylo. The new species can be easily identified by the combination of the following characters: anterior thorax with 13 chaetigers, interramal cirri absent, anterior thoracic neuropodia with 4 or 5 rows of uncini, intermixed with a few subuluncini in the first 1 or 2 rows, and a ventral fringe of numerous stomach papillae present on chaetigers 12–24. Phylo fimbriata is recorded for the first time from China seas.
