Ciliates are a speciose protozoan group and their diversity is still not well investigated in Korea. From our field surveys, 18 unrecorded ciliate species were collected from a total of nine localities in Korea. The field surveys were conducted in 2018 and 2019, and the unrecorded ciliates were found from terrestrial (moss and soil samples) and inland water (river and lagoon samples) habitats. The morphology of these ciliates was studied using the observation of living and silver impregnated (protargol) specimens. The present species belong to five classes as follows: 1) class Spirotrichea - Gonostomum kuehnelti, Quadristicha setigera, Lamtostyla decorata, L. islandica, L. longa, Anteholosticha brachysticha, Pseudobirojimia muscorum; 2) class Litostomatea - Apocoriplites lajacola, Epispathidium amphoriforme, Protospathidium muscicola, Phialinides australis, Paraenchelys wenzeli, Rimaleptus similis; 3) class Nassophorea - Drepanomonas revoluta; 4) class Colpodea - Bryometopus triquetrus; and 5) class Oligohymenophorea - Cyclidium glaucoma, Epistylis pygmaeum, Pseudovorticella vestita. The globular macronuclear nodules of P. vestita were observed for the first time in the Korean population.
