ṴH나ḑAEệ (ljḡ) ( Fig. 1 F-J)

Material examined. Forrest soil (pH 5) Bangeo-Dong, Ulsan Province, South Korea (35°28 ʹ N 129°25 ʹ E), collected by Kang-San Kim in February 2016 .

Diagnosis. Body size approximately 140 × 80 μm in vivo and 120 × 75 μm in impregnated specimens. Body shape broadly to narrowly reniform with a distinct postoral groove. Two postoral sacks. Contractile vacuole with distinct collecting canals extending to or near anterior body end. One macronucleus and one micronucleus. Cytoplasm colorless with oblong extrusomes. About 90 somatic and six vestibular kineties. About 55 left and 27 right polykinetids.

Remarks. Tillina minima is similar in appearance to T. magna . Tillina magna , a type species of Tillina , can be distinguished from T. minima based on the following features: body length (150-400 μm vs. 90-160 μm); number of micronucleus (more than two vs. single); and number of somatic kineties (about 133 vs. 90) ( Foissner, 1993).

Distribution. Africa, Australia, Europe, Japan, USA.

Deposition. Two voucher slides with protargol-impregnated specimens were deposited in the National Institute of Biological Resources in Korea (NIBRPR0000107257, NIBRPR0000107259).

Identifiers. Kang-San Kim and Gi-Sik Min.
