New records of 24 ciliate species (Protozoa, Ciliophora) collected in South Korea Author Kim, Ji Hye Natural Science Research Institute, Gangneung-Wonju National University, Gangneung, Republic of Korea Author Jung, Ji Hye Moon and Jae-Ho text Journal of Species Research 2018 7 4 291 314 journal article 10.12651/JSR.2018.7.4.291 2713-8615 13163147 1. Tracheloraphis dracontoides (Bullington, 1940) Borror, 1963 ( Fig. 1 ) Material examined. Marine water (salinity 29‰) collected from Anin Beach , Gangdong-myeon , Gangneung-si , Gangwon-do , Korea ( 37°44 ʹ 4.7 ʺ N , 128°59 ʹ 24.2 ʺ E ) on June 7, 2018 . Diagnosis. Extended body size 800-1000 × 30-40 μm in vivo ; body highly contractile and flexible with vermiform shape; 32-38 somatic kineties; glabrous stripe width about 15 μm; single nuclear group centrally locat- ed on main body and composed of 12-18 macronuclei and about 2 micronuclei; 2 types of cortical granules colorless: larger one disc-like shape, diameter about 1.5 μm; smaller one spherical to oval shape, size about 0.4 × 0.6 μm; cortical granules loosely arranged in middle line of glabrous zone; single circumoral kinety and obliquely arranged 2 or 3 brosse kineties. Distribution. U.S.A. , Korea . Remarks. The Korean population of T. dracontoides is different from the American population in the shape of body cross section (cylindrical vs. bean-shaped) ( Borror, 1963 ). The closest congener of T. dracontoides is T. aragoi (Dragesco, 1954) Dragesco, 1960 but they differ in the presence of macronuclear crystals (absent vs. present) and the distribution of cortical granules (regularly arranged vs. partially concentrated) ( Foissner and Dragesco, 1996 ). Voucher slides. Two slides of protargol-impregnated specimens were deposited at National Institute of Biological Resources, Korea (NIBRPR0000109426, NIBRPR0000109427) and three slides were deposited at the National Marine Biodiversity Institute of Korea (MABIK PR00043118-PR00043120).
