Preliminary Studies on Species of Hesionidae(Polychaeta)From Yellow Sea

Out of the 30 genera of the family Hesionidae,3 are considered typically interstitial poly- chaetes:Micophthalmus Mecznikov,1865,Hesionides Friedrich,1963 and Heteropodarke Hart- mann-Schr(?)der,1962.None of the species in the three genera was reported previously in China. In a study of polychaetes from the Yellow sea in 1987,three species belonging to the above genera respectively were first recorded in China. 1.Microphthalmus hartmanae pacificus Yamanishi,1984 Locality and habitat:3 spcimens from intertidal zone of median and coarse sand beaches of Dalian and Penglai. The present specimens correspond to Micophthalmus Yamanishi,1984 in the shape and arrangement of notochaetae,arrangement of neurochaetae,the number of teeth on Pectinate chaeta,the shape of anal of neurochaetae,the number of teeth on pectinate chaeta,the shape of anal lappet,length of anal cirri and other characters,but the simple neurochaetae and the blades of compound neurochaetae being smooth are different from Japanese species. 2.Hesionides arenaria Fricdrich,1937 Locality and habitat:40 specimens from intertidal zone of sand beach of Yantai. The present specimens correspond to Hesioanides arenaria Friedrich,1937 well. 3.Hderopodarke heteromorpha africana Hartmann-Schr(?)der,1974 Locality and habitat:3 specimens from intertidal zone of sand beach of Yantai. The present speimens correspond to Hetetppdarke heteromorpha africana Hartmann-Schr(?)der, 1974 well except for having fewer tentacular cirri.In the genus Heteropodarke,the number of ten- tacular cirri can vary depending on the body size of the individual.
