A New Freshwater Hypotrichous Ciliate, Trichototaxis songi sp. n. from Hangzhou, China (Ciliophora: Stichotrichina)
並列摘要
The morphology and infraciliature of a new hypotrichous ciliate, Trichototaxis songi sp. n., isolated from a freshwater pond in Hangzhou, China, were investigated using live observation and protargol silver impregnation method. Based on the current and previous data, the genus Trichototaxis is characterized by a combination of the following features, viz., one to more rows of left marginal cirri and one row of right marginal cirri; many frontal cirri in a bicorona, posteriorly continuous with midventral rows; transverse cirri present. The diagnosis for T. songi sp. n.: Freshwater Trichototaxis, long elliptical in outline, 160-280×60-110 μm in vivo and slight brick-reddish in colour; pellicle highly flexible, with underlying brick-red pigments, mainly grouped around cirri and dorsal cilia; single contractile vacuole located in posterior third to fourth of the cell; ciliature comprising about 60 adoral membranelles, bicorona of ca 10 cirri, 1 buccal, 2 frontoterminal and 2-4 transverse cirri, midventral rows of about 40 pairs/rows of cirri extending to transverse cirri; one to five rows of left marginal cirri and about 80 right marginal cirri; numerous macronuclear segments and usually 4 dorsal kineties.
