Free-living nematodes feed on bacteria, algae, fungi, dead organisms, and living tissues. They release nutrients for plant use and improve soil structure and water holding capacity. They are usually the most abundant type of nematodes in soil and marine environments. This study has been conducted to survey the distribution and identification of soil nematodes from rhizosphere soil of plant for investigation of indigenous species according to Convention on Biological Diversity. Three species of free-living nematodes belonging to the order of Dorylaimida were found from paddy soil and soybean fields, Miryang, Gyeongsangnam-do and one species was found from soil, Dokdo island, Gyeongsangbuk-do, Korea. Aporcelaimellus obtusicaudatus, Eudorylaimus arcus and Mesodorylaimus spengelii are newly collected from Korea. A. obtusicaudatus can be recognized by its large body, short odontostyle being much thicker than cuticle at the same level, well developed gonads, shape and length of the tail. E. arcus is distinctive because of the wide lateral field, tail form and supplement arrangement. M. spengelii is smaller species with short odontostylet, simple guiding ring. Female tail more or less uniformly attenuated, tip is not swollen, nor curved dorsally.
