4. Cultellothrix coemeterii (Kahl, 1943) Foissner and Xu, 2007 (Fig. 1D) Diagnosis: Body size 55 × 18 μm in protargol preparations; body narrowly spatulate with oblong oral bulge. Macronuclear nodule reniform. Contractile vacuole at posterior body end. Cytoplasm colorless. Usually 12 ciliary rows; dorsal brush positioned distinctly lateral side; anterior cilia moderately reduced. Extrusomes cylindrical, colorless. Circumoral kinety closed. Remark: It is first record of member belonging to the family Arcuospathidiidae from Korea. Other spathidiids were frequently occurred from our moss samples and they seem to be very diverse (Foissner and Xu, 2007). The other spathidiids occurred in our samples will be reported later with further investigation. Voucher slides: Two slides including protargol­impregnated specimens have been deposited in the National Institute of Biological Resources in Korea (NIBRPR0000 107140, NIBRPR0000107141).
