9. Pseudourostyla dimorpha Foissner, 2016 ( Fig. 2D)

Diagnosis. Body size approximate 180 × 30 μm in protargol preparations; body shape elongated ellipsoidal, flattened dorsoventrally, both body ends rounded; flexible. Nuclear apparatus composed of ca. 100 macronuclear nodules and several micronuclei throughout cytoplasm. Cytoplasm colourless. Movement, without any peculiarities, crawling on soil surface. Cirri pattern, on average, composed of 9 cirri forming bicorona, 1 buccal, 2 frontoterminal cirri, 8 cirral pairs, and 8 transverse cirri; 7 left and 5 right marginal rows.

Remarks. Pseudourostyla dimorpha includes two morphological types, broad and slender ( Foissner, 2016). In the moss-covered soil sample, we found only the slender type, which corresponded well with the original description.

Voucher slides. Two slides, including protargol-impregnated specimens (HG), were deposited at the National Institute of Biological Resources in Korea (NIBR

PR0000107201, NIBRPR0000107202).
