摘要:
We describe here a new species of Amphictene (Annelida, Polychaeta, Pectinariidae) from a depth of 1160 m off Kushiro, East Hokkaido, Japan. Amphictene hokkaido sp. nov. is characterized by the presence of following characters: a pair of ventral lappets in segment 1; ventro-median lobes in segments 2-4; anterior conical or rounded lappets on ventro-lateral lobe of segment 2; dorso-lateral pads in segments 3 and 4; 17 segments with chaetae on notopodia, 13 segments with uncini on neuropodia; notopodia in segment 21 with notopodial lappets beneath chaetal tuft; neuropodial uncini with 4-5 main teeth and subrostral process on basal prow; 7-9 pairs of scaphal hooks; scaphe with anterior median lobe and four pairs of lateral lobes; anal lobe with an anal cirrus and a row of postero-ventral minute cirri. We provide a diagnostic key to species of the genus.
