Aporcelaimellus donghwaens n. sp. is 2.8~2.9mm long, c=40.0~4.5, odontostyle 19~20$\mu\textrm{m}$ long and is characterized by possessing shorter odontophore, presence of cardiac disc and conoid tail. Labronema korandus n. sp. is 2.2~2.3 mm long, c=68~81, odontostyle 27~28$\mu\textrm{m}$, spicule 61$\mu\textrm{m}$ long and is characterized by having continuous lip region, circular vulva and cylindrical tail. Zalophidera longus n. sp. is 4.1~4.4mm long, c=107~130, spear 80~93$\mu\textrm{m}$ long and is characterized by large sized body, spear and spear extension. Discolaimoides bulbiferous and Diphtherophora communis were reported here for the first time in Korea.
