Jeju Island of South Korea is a volcanic island formed from eruption approximately two million years ago. Considering its origin and location closer to the subtropical waters, the difference in make-up of biodiversity has always been topic of interest to many experts. Five most naturally maintained beaches were selected from pre-examination and sediments were sampled using filter method. Results indicated nematodes belonging to families Chromadoridae, Desmodoridae, Xyalidae and Thoracostomopsidae were most abundant. For this study, five species belonging to the family Thornmjacostomopsidae Filipjev, 1927 discovered from the survey are redescribed. Of the five species, two belong to the genus Enoploides Saveljev, 1912, rest belong to Enoplolaimus de Man, 1893, Mesacanthion Filipjev, 1927 and Paramesacanthion Wieser, 1953 respectively. seventIMCO Posters presentations T1 82 New morphological details missed from the original descriptions are described from scanning electron micrographs. Description of the five species, diagnosis of its respective genera, and emended pictorial key to valid species are provided.
