2. Novistrombidium apsheronicum (Alekperov and

Asadullayeva, 1997) Agatha, 2003 ( Fig. 2)

Material examined. Brackish water (salinity 17.8‰) taken from the River Gyeongpocheon , Unjeong-dong , Gangneung-si, Gangwon-do, Korea (N37°47 ʹ 20 ʺ, E128° 54 ʹ 34 ʺ) on November 25, 2016 GoogleMaps .

Diagnosis. Body size, 70-85 × 45-50 μm in vivo; obconical with conspicuous apical protrusion located on anterior pole; hemitheca covering the posterior half of body; cytoplasm colorless, contains numerous 1-3 μm diameter spherical and transparent granules; extrusomes rodshaped in vivo; 1 J-shaped macronucleus, located anteri- or to posterior; 13-16 collar membranelles; 12-13 buccal membranelles continuous with anterior membranelles; girdle kinety composed of 49-52 dikinetids, spirally arranged; ventral kinety composed of 20-23 dikinetids, arranged longitudinally.

Distribution. Azerbaijan, Saudi Arabia, Korea (this study).

Remarks. Novistrombidium apsheronicum (Alekperov and Asadullayeva, 1997) Agatha, 2003 is separated from N. testaceum (Anigstein, 1914) by the arrangement of extrusomes (question mark-shaped in N. apsheronicum vs. C-shaped and almost horizontal in N. testaceum ) and the location of the micronucleus (close to right end vs. near the macronuclear segment junction) ( Agatha, 2003; Xu et al., 2009).

Voucher slides. Two slides, including protargol-impregnated specimens, were deposited at the National Institute of Biological Resources, Korea (NIBRPR0000107890, NIBRPR0000107891).
