We discovered three soil ciliates of the class Colpodea-Colpoda henneguyi Fabre- Domergue, 1889; C. lucida Greeff, 1888; and Bursaria truncatella Müller, 1773 from Obong-ri, Ayajin-ri and Elwang-ri (Korea), respectively. Colpoda henneguyi had the following features: often wider preorally than postorally, size in vivo 60-80 μm×50-70 μm; extrusomes indistinct in vivo, cylindroid approximately 1 μm long; notches caused by deep diagonal groove; yellowish globules on the cortex of the cell; 10-12 postoral kineties; silverline system aspera-type. Colpoda lucida exhibited the following features: broadly reniform, size in vivo 70-90 μm×50-70 μm; conspicuous extrusomes, 3.5-5 μm long in vivo, cylindroid to fusiform; 13-16 postoral kineties; silverline system cucullus-type. Bursaria truncatella had the following features: bursiform, size in vivo 300-470 μm×120-260 μm; macronucleus coiled with highly variable shapes, 600-1100 μm×30-40 μm long in vivo; micronuclei 16-25 in number, approximately 4 μm in diameter; extrusomes cylindroid, 3-4 μm long in vivo. This is the first report of colpodean ciliates from Korea, and we describe these species based on observations of live and impregnated (protargol and silver nitrate impregnation) specimens.
