10. Stylonychia ammermanni ammermanni View in CoL

Gupta et al., 2001 ( Fig. 10 View Fig )

Material examined. Freshwater taken from Danamdong, Incheon, Korea (37°33ʹ42ʺN 126°43ʹ37ʺE) on April 2018 GoogleMaps .

Diagnosis. Cell size 110-120 × 55-60 μm in protargol preparations, typical shape striking bulge in region of peristome, rigid; 44-48 adoral membranelles; cortical granules lacking; 2 macronuclear nodules, 2 or 3 micronuclei; 18 frontal-ventral-transverse cirri, 3 frontal, 1 buccal, 4 frontoventral, 3 postoral ventral, 2 pretransverse ventral, and 5 transverse cirri; 1 left (14-16 cirri) and 1 right (23-25 cirri) marginal cirral row; 6 dorsal kineties, 16-20 bristles in kinety 4; 3 caudal cirri.

Remarks. The subspecies called Stylonychia ammermanni koreana was established by Kumar et al. (2016). Stylonychia ammermanni koreana mainly differs from S. ammermanni ammermanni by the following two features: number of adoral membranelles (less than 44 vs. more than 44) and number of bristles in dorsal kinety 4 (less than 15 vs. more than 16) ( Kumar et al., 2016). Our Korean population resembles S. ammermanni ammermanni mainly due to the number of adoral membranelles (44-48) and number of bristles in kinety 4 (16-20).

Deposition. Two slides ( NNIBR2018113 IV1951, NNIBR2018113 IV1952) have been deposited at the Nakdonggang National Institute of Biological Resources ( NNIBR), South Korea .
