Taxonomy of trichodinids from the gills of marine fishes in coastal regions of the Yellow Sea, with descriptions of two new species of Trichodina Ehrenberg, 1830 (Protozoa: Ciliophora: Peritrichia)

Two new species of free-living marine nematodes, Daptonema longiapophysis sp. nov. and Cobbia sinica sp. nov. from the Yellow Sea, China are described and illustrated. Daptonema longiapophysis sp. nov. is characterized by spicules with a projection on the ventral and dorsal side respectively and the length of the gubernacular apophysis longer than the length of spicules. Cobbia sinica sp. nov. is characterized by one big dorsal tooth, long conico-cylindrical tail and gubernaculum with a small dorsal apophysis.

A New Species

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.

The Right

Two new species of ciliates parasitizing marine molluscs in the Yellow Sea were described using live observation, protargol and wet silver impregnation: Sphenophrya solinis sp. nov. from the gills of Solen grandis and Planeticovorticella paradoxa sp. nov. from the gills as well as the mantle cavity of Meretrix meretrix. Sphenophrya solinis is elongate boat-shaped, and characterized by having the right system of 5–6 kineties more or less distinctly longer than the left system of 3–5 kineties and the bud formed on the dorsal left of body during budding. Planeticovorticella paradoxa is a second member of the genus Planeticovorticella, and characterized by the free-swimming, cylindroidal trophonts usually with no stalk or with a very short and non-contractile stalk, the C-shaped macronucleus longitudinally oriented in mid-body, and the apically located contractile vacuole. The morphology, infraciliature and morphometry of the two new species were studied in detail and compared with those of their most similar congeners.
