3. Bistichella variabilis He and Xu, 2011 ( Fig. 3 View Fig )
Material examined. Terrestrial soil sample collected from a footpath behind Gangneung-Wonju National University, Gangneung, Korea (37°46 ʹ 30.4 ʺ N, 128°51 ʹ 46.2 ʺ E) on 3 January 2020 GoogleMaps .
Diagnosis. Body size about 155 × 40 μm after protargol impregnation (n = 5); body elongate; 4 macronuclear nodules and 4 or 5 micronuclei; adoral zone of membranelles covered about 25% of cell length with about 36 membranelles; 1 right and 1 left marginal row with 48 cirri each on average, right marginal row commences on dorsal side; 3 frontal, about 6 buccal, frontoventral rows III- VI composed of 1-3, 5 or 6, 33-41, 6-10 cirri each, and 5 transverse cirri; 3 dorsal kineties.
Distribution. China and Korea.
Remarks. The Korean population of Bistichella variabilis agrees with the type population described by He and Xu (2011), but has a smaller body size and less number of cirri. This species was missed by Foissner (2016), who improved the generic diagnosis of the genus Parabistichella Jiang et al., 2013 . This species is awaiting to be transferred to the genus Parabistichella because of the presence of the transverse cirri, which is a characteristic of the genus Parabistichella .
Voucher slides. Two slides with protargol-impregnated specimens were deposited at the Nakdonggang National Institute of Biological Resources (NNIBRPR20107, NNI- BRPR20108).
