Material examined. Terrestrial moss collected from Gyodong , Gangneung-si, Gangwon-do, Korea (37°45 ʹ 51.28 ʺ N, 128°52 ʹ 31.59 ʺ E) on September 9, 2017 .

Diagnosis. Body size 70-85 × 22-25 μm in vivo; 58-69 × 16-19 μm after protargol impregnation; body ellipsoidal shape; contractile vacuole at about left mid-body with 2 collecting canals; ellipsoidal cortical granules irregularly arranged on dorsal side, colorless; 2 ellipsoidal macronuclei, 2 spherical micronuclei; undulating membranes Gonostomum -like pattern; 28-30 adoral membranelles; 3 frontal cirri; frontoventral row 2 composed of 2 cirri; frontoventral row 3 consisted of 3-5 cirri; frontoventral row 4 composed of 12-14 cirri; frontoventral row 5 comprised of 15-16 cirri; 2 transverse cirri; 9-10 left marginal cirri; 10-14 right marginal cirri; 3 caudal cirri; 3 dorsal kineties.

Distribution. France, High Arctic, Namib Desert, Romania, Korea.

Remarks. The Korean population of W. bujoreani is different from the French and Namibian populations in the presence of contractile vacuole canals (present vs. absent vs. absent) ( Berger and Foissner, 1989; Foissner et al., 2002). Wallackia schiffmanni Foissner, 1976 is the most similar to W. bujoreani , however the former can be distinguished from the latter by the habitat (limnetic vs. terrestrial), the number of cirri in frontoventral row 2 (6 in drawing vs. 2), frontoventral row 3 (6 in drawing vs. 3-5), the posteriorly elongated dorsal bristles (present vs. absent) and the shape of cortical granules (elongated ellipsoidal vs. short ellipsoidal) ( Berger, 2011).

Voucher slides. Two slides of protargol-impregnated specimens were deposited at National Institute of Biological Resources, Korea (NIBRPR0000109417, NIBRPR0000109418).
