Abstract

Two euplotid ciliates collected from the estuarine littorals in Korea were identified as Euplotes vannus ($M\ddot{u}ller$, 1786) and E. parawoodruffi Song and Bradbury, 1997. These species are reported taxonomically for the first time from Korea. These two species are redescribed with illustrations, photos and biometry based on live and silver impregnated specimens. Diagnostics of each species are as follows. E. vannus: size in vivo $94-111{\times}55-75{\mu}m$ (average $103{\times}60{\mu}m)$, adoral zone of membranelles (AZM) 70% of cell length with 57-74 adoral membranelles (AM) and terminating close to hook-shape, macronucleus (Ma) C-shaped with twisted foot-like, 10 frontoventral (FVC), 5 transverse (TC), 4-7 (average 5) caudal cirri (CC), 9-10 dorsal kineties (DK), mid dorsal kinety with 15-22 cilia; silver-line system single vannus type. E. parawoodruffi: size in vivo $125-163{\times}72-100{\mu}m$, (average $141{\times}87{\mu}m$), dorsally strongly arched, body shaped reserved triangular. AZM 67-83% of cell length with 60-85 AMs, 9 FVC, 5 TC, 4 CC, 9 DK; mid-dorsal kinety with 20-30 cilia, double-eurystomus type, T-shaped Ma with equal sized right and left arms or right arm shortened slightly.
