Collected from seawater at Bongpo Port , Bongpo-ri , Toseong-myeon , Goseong-gun , Gangwon-do , Korea ( 38°15 ʹ N , 128°34 ʹ E ), October 22, 2017 . Diagnosis . Size approximately 95-110 × 45-60 μm after protargol impregnation; ellipsoidal body outline, anterior and posterior ends slightly narrow, body length to width ratio of 1.6-2.5: 1; spindle-shaped extrusomes densely arranged beneath pellicle; buccal field approximately 19% of body length; approximately 88 somatic kineties; 3 or 4 vestibular and 5 postoral kineties; peniculi 1-3 each with 4 kinety rows; 1 ellipsoidal macronucleus; one contractile vacuole. Voucher slide . A slide of protargol-impregnated specimens has been deposited at the National Institute of Biological Resources, Korea (NIBRPR0000109476). Remarks . Frontonia canadensis was originally describ- ed by Roque and Puytorac (1972) and re-described by Pan et al. (2013) . The Korean population of F. canadensis closely resembles the description of the Chinese population in terms of the body shape, the number of somatic, postoral, and vestibular kineties, and the number of peniculi 1-3 kinety rows ( Pan et al. , 2013 ).
