- Аннотация: In the context of exploration of meiofauna in a sandy intertidal zone of Jeju Island (South Korea), over 70 nematode species were identified, some of them are proved to be new for science. Two new free-living marine nematode species of the family Selachinematidae (Chromadorida, Selachinematidae, Choniolaiminae) are described from the intertidal sandy sediments of Jeju Island (South Korea). Gammanema okhlopkovi sp. n. is most close to G. anthostoma Okhlopkov, 2002 and differs by longer cephalic setae (8.5‒19 μm in G. okhlopkovi versus 6‒7.5 μm in G. anthostoma) and by presence of precloacal supplementary organs. Genus diagnosis of Gammanema is updated. The genus includes fourteen valid species, while three species are considered species inquirendae due to incomplete diagnoses and illustrations impeding their correct recognition. An annotated list of valid and invalid Gammanema species is provided. A pictorial key for valid Gammanema species is constructed; it consists of two components, (1) simplified images of heads and (2) a table summarizing most significant measured and numeric characters between species. Latronema obscuramphis sp. n. differs from its related species L. aberrans (Allgén 1934), L. annulatum Gerlach, 1953 and L. spinosum Andrássy, 1973 by body size, number of supplementary organs, tail shape, length of spicules and cuticle ornamentation.
