並列摘要


The morphology and infraciliature of a new marine hypotrichous ciliate, Erniella wilberti sp. n., collected from a shrimp culturing pond near Qingdao (Tsingtao), China, are investigated using living observations and protargol silver impregnation method. The new species is characterized by: 80-180×25-70 μm in vivo with elongated body shape and thin hyaline margin encircling the whole cell; arc-shaped cortical structures arranged in 3 rows on dorsal side; bipartite adoral zone each with 8-12 and 16-20 membranelles respectively; 4-6 frontal, 1 buccal and 2-5 transverse cirri; 2 ventral cirral rows extending to posterior half of body; 3 dorsal kineties; 2 macronuclear nodules and 1-3 micronuclei.
