1. Pelagostrobilidium conicum (Kahl, 1932) Liu, Yi,

Lin, Warren, and Song, 2012 ( Fig. 1)

Material examined. Marine water (salinity 31‰) taken from Songji Lake , Oho-ri , Jugwang-myeon , Goseonggun, Gangwon-do, Korea (N38°20 ʹ 11 ʺ, E128°30 ʹ 58 ʺ) on April 28, 2017 .

Diagnosis. Body size 29-35 × 14-17 μm in preparations; obconical to inverted pyriform; six somatic kineties commencing at same level; somatic kinety 1 posteriorly extending near posterior end, somatic kineties 2 and 3 converging posteriorly; single macronucleus, horizontal, C-shaped; 23-28 adoral membranelles.

Distribution. Czech Republic, Germany, Korea (this study).

Remarks. Pelagostrobilidium conicum is closely related to P. kimae Agatha and Strüder-kypke, 2004, but has a different somatic kinety 1 length (extended vs. shortened) and the position of somatic kinety 2 is different (anteriad vs. posteriad) (Agatha and Strüder-kypke, 2004).

Voucher slides. Two slides, including protargol-impregnated specimens, were deposited at the National Institute of Biological Resources, Korea (NIBRPR0000107952, NIBRPR0000107953)
