3. Blepharisma hyalinum Perty, 1849 ( Fig. 1C )

Diagnosis: Body size 50­75 × 10­25 μm in protargol preparations; body shape roughly elliptical to fusiform; anterior end bluntly pointed and slightly curved. Nuclear apparatus composed of broadly elliptical macronuclear nodule and several micronuclei. Contractile vacuole at posterior body end. Cytoplasm colorless. Adoral zone composed of 19­25 membranelles and linear paroral membrane; buccal field about 50% of cell in length. Somatic kineties consisted of 11­15 rows which curved at anterior half body.

Remark: Of the species belonging to the genus Blepharisma , three species were reported from Korea ( Lee and Shin, 2009; Shazib et al., 2014). They are usually reddish or bluish. However, depending on the culture condition, their color could be changed ( Foissner et al., 2002). Blepharisma hyalinum is colorless and can be distinguished from the congeners by the color, and number of adoral membranelles and somatic kineties ( Aescht and Foissner, 1998).

Voucher slides: Two slides including protargol­impregnated specimens have been deposited in the National Institute of Biological Resources in Korea (NIBRPR0000 107126, NIBRPR0000107127).
