A new species and new recorded species of Orbiniidae Hartman, 1942 (Annedia: Polychaeta) from China

Abstract

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