13. Paragastrostyla terricola (Foissner, 1988) Berger,

2006 ( Fig. 2G)

Diagnosis. Body size approximate 80 × 15 μm in protargol preparations; body shape ellipsoidal with narrow posterior body end, flattened dorsoventrally. Nuclear apparatus composed of approximate 15 macronuclear nodules with several spherical micronuclei at left mid-body. Cortical granules present; cytoplasm colourless. Movement, without any peculiarities, crawling on soil surface. Cirri composed of 3 frontal, 3 frontoterminal cirri, 3 midventral cirral pairs, and a longitudinal row composed of 6 cirri. 1 left and 1 right cirral row. 2 dorsal kineties; caudal cirri present.

Remarks. This is the first record of the genus Paragastrostyla in Korea. Paragastrostyla includes two species, which can be separated based on the cortical granules (presence in P. terricola vs. absence in P. lanceolata ; Berger, 2006).

Voucher slides. Two slides, including protargol-impregnated specimens (TB1), were deposited at the National Institute of Biological Resources in Korea (NIBR PR0000107197, NIBRPR0000107198).
