2. Arcuseries warreni (Song & Wilbert, 1997)

Huang et al., 2014 ( Fig. 2 View Fig )

Material examined. Seawater (28.8 ‰) from Incheon Port, Korea (37°26ʹ57ʺN, 126°35ʹ37ʺE), on May 2018 GoogleMaps .

Diagnosis. Cell size 65-80 × 25-30 μm in protargol preparations, oval shape, and flexible; adoral zone 32% of body length, 28-30 adoral membranelles; 43-60 macronuclear nodules; conspicuous cortical granules arranged around dorsal bristles, erythrocytes-like granules densely distributed in cytoplasm; 3 frontal and 2 frontoterminal cirri; 1 buccal cirrus; 7-9 midventral pairs; 10- 12 transverse cirri and 2 pretransverse ventral cirri; 1 left (20-25 cirri) and 1 right (20-27 cirri) marginal cirral row; 3 dorsal kineties; hair-like ejected granules present; caudal cirri lacking.

Remarks. Arcuseries warreni can be easily distinguished from other Arcuseries species by conspicuous erythrocyte-like granules and hair-like ejected granules. In the Korean population of A. warreni , cortical granules were mainly arranged along with cirri, and around dorsal bristles ( Fig 2B, C View Fig ).

Deposition. Two slides (NIBRPR0000109459, NIBRPR0000109450) have been deposited at the National Institute of Biological Resources (NIBR), South Korea.
