Hysterothylacium sinense sp. nov. was collected from the intestine of six species of marine fishes, Astroconger myriaster ( Brevoort), Trichiurus haumela ( Forsskal), Saurida elongata Temminck and Schlegel, Coryphaena hippurus Linnaeus, Sillago sihama ( Forsskal) and Argyrosomus argentatus ( Houttuyn) in the Yellow Sea, China. The new species differs from congeners by the presence of broad lateral alae, the length of the intestinal caecum ( 1.26-2.33mm long, 61.6 - 75.0% of oesophageal length), the number and arrangement of caudal papillae ( 22 - 27 pairs of preanal, 1 pair of paranal and 3 pairs of postanal papillae), the size of the spicules ( 1.65 - 2.67mm long, 5.1 - 9.5% of body length) and the vulval position ( 23.9 - 31.7% from anterior end). A key to the species of the genus Hysterothylacium is also given.
