摘要
Ciliates are highly diverse in the benthos where there are rare species to be unrevealed and described. By isolating species during successive and diversified cultivations, we discovered several new and interesting taxa from the top layer sediment of a muddy site in the Ganghwa tidal flat. These include three new species Spirodysteria ganghwaensis n. sp., Uronemella parafilificum n. sp., Zosterodasys minuta n. sp., and one poorly known form Loxophyllum chaetonotum Borror 1965. The morphology of live cells and infraciliature of these four species are described based on living observations, protargol impregnations, and morphometrics. Diagnoses and improved definitions are also provided. The newly established genus Spirodysteria n. g. differs from Dysteria mainly in its spirally twisted body shape. Spirodysteria kahli (Tucolesco 1962) n. comb. (formerly Dysteria kahli Tucolesco 1962) has been included in this new genus.
