They were Thalassiosira oceanica Hasle, Navicula britannica Hustedt et Aleem, Nitzschia leehyi Fryxell and Synedra indica Taylor. Detailed description of the taxonomic characteristics with TEM photographs of the four species and their ecological behavior and distribution is given in this paper.展开更多

Nematodes from the two areas were identified consistently, and were characterized by a heavy cephalic sclerotization, extending posteriorly up to two body annuli, stylet 11-13 p.m long, elongating conoid tail, and becoming thinner from vulva. Males were not found. Pratylenchus ekrami is close to Pratylenchus vulnus, but the most critical characteristics between the two species were the number of lip annuli, stylet size, and shape of stylet knobs.

S. commune was characterized by rounded scutella, which was varied from two annules anterior to the anus and five annules posterior. The lateral field was not areolated at the level of scutella. S. magniphasma was characterized by varying scutellum, about 7.0 μm in diameter, in position from four annules posterior to four annules anterior to the anus, and areolated at the level of the scutellum.展开更多

Two new species, Eucheilota carinata sp. nov. and Halopsis nanhaiensis sp. nov., are described and illustrated. One genus, Staurostorna, and two species, Staurostorna sp. and Octophialueiurn aphrodite （Bigelow, 1928）, are first recorded in China seas. The key to all medusa genera and species of Lovenellidae and Malagazziidae are presented. Other data are briefly summarized to the list and distribution of species presented on the family Laodiceidae, Lovenellidae, Malagazziidae and Mitrocomidae in the South China Sea. The type specimens are deposited in the Third Institute of Oceanography, State Oceanic Administration, China.展开更多
