2012 ( Figs. 3C, D ) ẖNjḇùöAEệ (ṵÿ) Pseudourostyla franzi Foissner, 1987

Material examined. Goesan-gun (36°48′38.21″N, 127° 57′37.11″E), Chungcheongbuk-do, South Korea; 1 September 2015.

Deposition. NIBRPR0000107159, NIBRPR0000107160.

Distribution. China, Costa Rica, Australia, Kenya, Namibia, and South Korea.

Diagnosis. Cell size 160 - 230 μm × 40 - 55 μm in vivo; body highly flexible with elliptical shape. Exactly, 232 - 323 macronuclear nodules with more than 10 micronuclei. Contractile vacuole at left mid-body. Cortical granules arranged around cirri and dorsal bristles. Exactly, 60 - 75 adoral membranelles, bicoronal frontal cirri rows, 3 or 4 buccal cirrus and 1 - 3 parabuccal cirri present, invariably 2 frontoterminal cirri, 7 - 11 transverse cirri present. midventral cirral pairs present. Exactly, 7 or 8 left and 7 or 8 marginal cirral rows. Invariable 4 bipolar dorsal kineties, caudal cirri lacking.

Remarks. Hemicycliostyla sphagni differs from H. franzi in the following features: body color (green vs. brown) and transverse cirri (lacking vs. invariably present) ( Paiva et al., 2012).
