Three unrecorded species of free-living marine nematodes, belonging to genus Enoplus Dujardin, 1845 collected from rocky intertidal seagrass on the eastern coast of Korea, are described and illustrated. Enoplus taipingensis Zhang and Zhou, 2012 is characterized by longer body size, a series of lateral setae throughout the tail in male, the presence of trumpet-shaped precloacal supplement with well-dilated proximal end, and the presence of spicules with five to eight semicircular plates. Enoplus meridionalis Steiner, 1921 is characterized by the presence of trumpetshaped precloacal supplement with slightly dilated proximal end, paired massive spicules, and tail with two pairs of stout terminal setae. Enoplus mammillatus Timm, 1959 is easily distinguished from the congeners by narrow tubular-shaped precloacal supplement. In this study, we provide detailed morphological features of three Enoplus species by differential interference contrast microscopy and scanning electron microscopy. This is the first report on the species of the genus Enoplus from the Korean waters.

문제 정의
However, the taxonomic report on the genus Enoplus of Korea in the intertidal algae is entirely unknown. The purpose of this study is to report taxonomic description of three unre-corded species belonging to genus Enoplus collected from rocky intertidal seagrass on the eastern coast of Korea.
가설 설정
Remarks: Enoplus mammillatus Timm, 1959 was firstly described from the Arabian Sea. Enoplus mammillatus is easily distinguished from the other species of the genus by narrow tubular-shaped precloacal supplement.

1993). Specimens were examined, photographed and drawn using Nomarski differential interference contrast (DIC) with an Olympus BX53 microscope equipped with a drawing tube and a DIXI 3000 camera, and quality enhanced portable photoshop software. Specimens selected for scanning electron microscopy (SEM) were fixed in 5% formalin, washed in distilled water, and critical point dried.

Marine nematodes were obtained from washing of inter tidal sediment. Samples were collected from rocky intertidal seagrass on the eastern coast of Korea. Samples were filter ed through a 67 μm mesh sieve in the field after freshwater rinsing for less than a minute for osmotic shock (Kristensen and Higgins 1989), and then fixed in 5% formalin in sea water.
