2000) Berger, 2008 ( Fig. 2 )

Material examined. Soil sample taken from Wangsan-ri, Jung-gu, Incheon, South Korea (37°26 ʹ 47 ʺ N 126°23 ʹ 40 ʺ E) on February 2018 .

Diagnosis. Cell size 60-70 × 15-20 μm in protargol preparations, elongated ellipsoidal, flexible; adoral zone 27% of body length; contractile vacuole at left mid-body; conspicuous cortical granules, colorless, arranged around dorsal bristles; 11-14 macronuclear nodules with 2 or 3 micronuclei; 3 frontal and 2 frontoterminal cirri; 1 buccal cirrus; 8-10 cirri in midventral complex slightly zigzagging; 3 or 4 transverse cirri; 1 left (14-16 cirri) and 1 right (15-18 cirri) marginal cirral row; 4 dorsal kineties (including dorsal marginal kineties) with 2 basal bodies in kinety 4; caudal cirri lacking.

Remarks. The Korean population is highly similar to the populations in Tenerife (type) and Berlin based on the number and the disposition of cirri and macronuclear nodules, though it differs from other populations based on the pretransverse ventral cirrus (absent vs. present) ( Berger, 2008).

Deposition. Two voucher slides with protargol-impregnated specimens are deposited in the National Institute of Biological Resources in Korea (NIBRPR000010445, NIBRPR000010446).
