7. Uroleptoides magnigranulosus ( Foissner, 1988)

Berger, 2008 ( Fig. 7 )

Material examined. Soil sample taken from Wangsan-ri, Jung-gu, Incheon, South Korea (37°26 ʹ 47 ʺ N 126°23 ʹ 40 ʺ E) on February 2018 .

Diagnosis. Cell size in protargol preparations 75- 100 × 35-40 μm on average, elliptical body shaped, flexible; adoral zone about 28% of body length, 21-28 adoral membranelles; contractile vacuole at slightly ahead of mid-body near left cell margin; conspicuous cortical granules arranged near cirri, colorless; 2 macronuclear nodules with 2 micronuclei; 3 frontal cirri; 2 amphisiellid median cirral rows; 1 buccal cirrus; 3 or 5 cirri left of anterior end of amphisiellid median cirral row; 5 or 6 transverse cirri; 1 left (32-35 cirri) and 1 right (32-43 cirri) marginal cirral row; 3 dorsal kineties; caudal cirri lacking.

Remarks. The major distinguishing features of Uroleptoides magnigranulosus from its congeners are the following combination of two features: having distinct cortical granules and amphisiellid median cirral rows that are arranged in two parts. The morphological features of the Korean population are very similar to those of the type population ( Kenya), and the former only differs from the latter by the number of cirri in amphisiellid median cirral row (21-26 vs. 12-19) ( Foissner, 1988).

Deposition. Two voucher slides with protargol-impregnated specimens are deposited in the National Institute of Biological Resources in Korea (NIBRPR0000109450, NIBRPR0000109451).
