Abstract
Hysterothylacium sinense sp. nov. was collected from the intestine of six species of marine fishes, Astroconger myriaster (Brevoort), Trichiurus haumela (Forsskål), Saurida elongata Temminck and Schlegel, Coryphaena hippurus Linnaeus, Sillago sihama (Forsskål) 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.References
