英文摘要：

One new species and 5 domestic new records of soil ciliates collected from the Scenic Spots and Historic Sites of Maijishan and Xinglongshan National Nature Reserve,Gansu were described in this paper. They are Keronopsis paradieckmanni sp. Nov.,Pseudochilodonopsis polyvacuolata, Tetrahymena pyriformis,Sterkiella cavicola, Cyrtohymena tetracirrata and Euplotes elegans. The new species is characterized as follows： Size in vivo 180-320μm×75-110μm;elongated elliptical with both ends more or less broadly rounded;dorsoventmlly flattened; usually 3-4 shortened elliptical macronudei; 4 spherical micronudei observed; 1 contractile vacuole. 6-8 frontal cirri; 5-8 buccal cirri; 3-4 rows of frontoventral cirri; 2 rows of ventral cirri, the right one reached the transverse cirri directly and the left one with 2 breaks ended above the uansverse drri; one left and one right row of marginal cirri, the right one extended on dorsal side anteriorly; 5-9 transverse cirri; no caudal cirri; 3 rows of dorsal bristles. AZM with 43-50 membranelles occupied about 1/4-1/3 of body length; paroral and endoral membrane curved with the former crossed over the latter about its anterior or posterior 1/3. Type specimens of new species were deposited in Institute of Ecology and Biodiversity, College of Life Sdence, Northwest Normal University, Lanzhou, China.
