2000) Berger, 2008 ( Fig. 2 View Fig )

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 GoogleMaps .

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).
