Korean populations match Kahl’ s (1930) description and Foissner’ s (1984) re-description in their narrowly spatulate body, prominent oral bulge papillae armoured by batteries of rod-shaped extrusomes, several scattered macronuclear nodules, and inconspicuous dorsal brush. However, Korean specimens are smaller than Kahl’ s individuals (150– 190 µm vs 170–260 µm), but their size falls well within the range (100–200 µm) reported by

that the difference in number of macronuclear nodules can be attributed to life-cycle stage. The length of extrusomes is very similar among all populations: about 13 µm in both Kahl’ s and Korean specimens and 10–12 µm in Foissner’ s individuals. Likewise, the number of ciliary rows seems to be similar between Korean and

The second scenario is favoured by molecular analyses (see below). However, the matter is more complex, because Korean populations are not monophyletic and none of them group with the Austrian isolates investigated by
