Specimens were collected at Yap seamount and Caroline seamount in the Northwest Pacific Ocean. Poliopogon distortus sp. nov. contains oval macramphidiscs, three categories of amphidiscs, clavate monaxons and sceptres, making it distinguished from the eight known congeners easily. This is the fourth record of genus Poliopogon from the Northwest Pacific Ocean. We also used a partial sequence of 16S rDNA gene to confirm the family assignment of the new specimen.展开更多

It has been misidentified as Asychis gangeticus Fauvel, 1932 since Uschakov and Wu （1962）. Here, we recognized it as a new species based on combination of the following characters： dark-brown pigmentation spots on nuchal grooves and first three chaetigers; glandular pattern on chaetigers 4-6; preanal achaetigerous segments absent; anal plaque trumpet- shaped with a disc-shaped dorsal lobe; notochaetae consisting of geniculate capillaries and fine capillaries with or without spinose spiral bands; neurochaetae presented as a single row of rostrate uncini. Asychis gangeticus differ from the new species in having no pigmentations on body and a triangular dorsal lobe of anal plaque. Distribution region of this species have moved northward significantly from sea area south of Changjiang Estuary since the 1950s.展开更多

This is also the first report of the genus Willenstenhelia from the China seas. The new species differs from congeners by the combined characters： all somites without spinules on surface except anal somite; third segment of female P4 exopod with two inner setae; female P5 baseoendopodal lobe with four elements and P5 exopod with sharp apical spine; caudal ramus about six times as long as broad.展开更多
