Here, Phyllochaetopterus hainanensis n. sp., a new species collected from Hainan Island （China）, is reported. It is characterized by having a V-shaped peristomium, two eyespots covered by a pair of large curved peristomial notopodia （cirri located beneath the palps）, 13-14 chaetigers in the anterior body region, with three enlarged modified chaetae on the fourth notopodium, and more than five chaetigers in the middle body region. The modified chaeta has a slightly inflated head with an obliquely truncate end. The new species resembles Phyllochaetopterus socialis Clapar6de, 1869, but differs in the shape of peristomial notopodia and peristomium. Twelve species of Phyllochaetopterus have been described from the Pacific Ocean, including the new species described here. An identification key to the known Pacific species is provided together with a brief discussion of the taxonomic value of the eyespots for the genus.展开更多

S piochaetopterus koreana is distributed in the Yellow, East China and South China Seas. Sp iochaetopterus sanbanzensis is widely distributed in the muddy benthic environment of the Yellow Sea. Detailed descriptions and illustrations of each species are provided.展开更多
