Abstract

Marine benthic ciliates were collected from four rocky intertidal pools along the eastern and southern coasts of Korea from 2012-2013. Ciliate specimens were examined by observing living and stained cells. Four ciliate species were new to Korea based on morphological characteristics as follows. (1) Aspidisca polypoda (Dujardin, 1841): small bean-shaped (ca. 30 μm), eight conspicuous dorsal ridge, polystyla-arrangement of frontoventral cirri; (2) Epiclintes auricularis auricularis (Claparède & Lachmann, 1858): tripartite and auriform body (ca. 300 μm), 46 adoral membranelles, one or two frontal and 23 transverse cirri, 12 oblique fronto-midventral rows; 59 left and 71 right marginal cirri; (3) Pseudochilodonopsis marina Song, 1991: reniform body (ca. 50 μm), two obliquely positioned contractile vacuoles, seven left and five right kineties, five fragmented preoral kineties; (4) Dysteria semilunaris (Gourret and Roeser, 1888): oval-shaped (ca. 30 μm), two longitudinally positioned contractile vacuoles, conspicuous longitudinal grooves on both plates, four or five right kineties, one short row below frontoventral kineties.
