4. Litonotus alpestris Foissner, 1978 View in CoL ( Fig. 4 View Fig )

Material examined. Brackish water (salinity 7.9‰) collected from the River Gyeongpochen , Unjeong­dong , Gangneung­si, Gangwon­do, Korea (37°47 ʹ 20 ʺ N, 128° 54 ʹ 34 ʺ E) on August 24, 2017 GoogleMaps .

Diagnosis. Body size 25­35 × 10­20 μm in vivo; body lanceolate shape, colorless; cortical granules colorless, 0.5­0.7 μm in diameter, irregularly arranged between somatic kineties; 1 contractile vacuole subterminally locat­ ed; 1 globular macronucleus size about 7 × 6 μm; 1 micronucleus size about 1.6 × 1.7 μm; 3 right side somatic kineties; 3 left side somatic kineties; perioral kinety (PK) 1­3, PK1 on left side, PK2, 3 on right side.

Distribution. Austria, Germany, Korea.

Remarks. The Korean population of L. alpestris is slightly different from the Austrian population in the body length (25­35 μm vs. 30­50 μm), the macronucleus length (7 μm vs. 10 μm), the number of right somatic kineties (3 vs. 3 or 4) and number of left somatic kineties (3 vs. 3 or 4) ( Foissner et al., 1995). Litonotus alpestris differs from L. bonnensis Song and Wilbert, 1989 in the number of right somatic kineties (3 vs. 6) and the number of left somatic kineties (3 vs. 6) (Song and Wilbert, 1989). Litonotus alpestris differs from L. uninucleatus (Kahl, 1931) in the body length (25­35 μm vs. 30­60 μm) and the anterior and posterior ends (broadly rounded vs. sharply rounded) (Song and Wilbert, 1989). Litonotus alpestris is distinguished from L. crystallinus Vuxanovici, 1960 in the number of macronuclear nodules (1 vs. 2) ( Foissner et al., 1995).

Voucher slides. Two slides of protargol impregnated specimens were deposited at National Institute of Biological Resources, Korea (NIBRPR0000107965, NIBRPR00001 07966).
