Two new species of the family Enchelidiidae Filipjev, 1918 were collected from marine sediments near Maemul Island in South Korea: a new species of Abelbolla Huang & Zhang, 2004 and a new species of Ledovitia Filipjev, 1927. Abelbolla maemulensis sp. nov. is characterized by its small size (1,493 × 38 µm, body length × maximum body diameter); the presence of a circular amphid; the gubernacular apophysis with swollen distal tip; and the complex structure of the gubernaculum. It is close to Abelbolla huanghaiensis Huang & Zhang, 2004, but differs by the structure of gubernacular apophysis and body length (1,493 vs 2,303 µm). Ledovitia brevis sp. nov. can be separated from its congeners by its small size of body, the length of gubernacular apophysis, and the length of the spicules. It is close to Ledovitia pharetrata Wieser, 1953a, but differs by the length of the body (1,699 vs 2,640 µm) and the spicules (40 vs 100 µm).
