Abstract:Four hypotrich ciliate species new to China belonging to two genera were isolated from soil in Qingdao and morphologically investigated using non-flooded Petri dish method, live observation and protargol impregnation techniques. These are: Cyrtohymena australis Foissner,1995,C. quadrinucleata (Dragesco & Njine, 1971), C. candens (Kahl, 1932), and Australocirrus oscitans Blatterer & Foissner, 1988. Supplementary descriptions of the live morphology and infraciliature of these ciliates were provided in detail, and compared with original descriptions and those of related populations.
