Notohymena antarctica Foissner, 1996 ( Fig. 2F ) Diagnosis: Body size 80 × 20 μm in protargol preparations; body shape ellipsoidal, flattened dorsoventrally, both body ends rounded; flexible. Nuclear apparatus composed of two macronuclear nodules at left mid­body. Cytoplasm colorless. Movement, without any peculiarities, crawling on soil surface. Eighteen frontal­ventral­transverse cirri composed of three frontal, one buccal, four frontoventral, three postoral ventral, two pretransverse ventral, and five transverse cirri.

The Korean population of N. antarctica were very rarely occurred from our samples and only two stained samples with brief observation in vivo were obtained. For precise description and identification, further investigation is necessary for the Korean population. Voucher slides: Two slides including protargol­impregnated specimens have been deposited in the National Institute of Biological Resources in Korea (NIBRPR0000 107122, NIBRPR0000107123).
