( Fig. 5 )

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 about 80 × 15 μm in protargol preparations, elongated ellipsoidal body shaped, flexible; adoral zone about 25% of body length; contractile vacuole at left mid-body; 4 macronuclear nodules with 2 or 3 micronuclei; 3 frontal and 2 frontoterminal cirri; 1 buccal cirrus; 4 cirri in left of anterior end of amphisiellid median cirral row; 1 pretransverse ventral cirrus and 3 transverse cirri; 1 left (about 26 cirri) and 1 right (about 25 cirri) marginal cirral row; 4 dorsal kineties (including dorsal marginal kineties); caudal cirri lacking.

Remarks. The Korean population only differs from the type population ( Japan) in pretransverse ventral cirri (present vs. absent) ( Berger and Foissner, 1989). This species can be separated from Hemisincirra quadrinucleata , by the adoral zone pattern of membranelles (continuous vs. discontinuous) and the number of dorsal kineties (4 vs. 3) ( Berger, 2008).

Deposition. One voucher slide with protargol-impregnated specimens is deposited in the National Institute of Biological Resources in Korea (NIBRPR0000109448).
