The Korean population of the sword-tailed cricket subfamily Trigonidiinae is reviewed for the first time. Four members of the crickets are confirmed based on the examined material, those are Metioche japonica (Ichikawa, 2001), Svistella bifasciata (Shiraki, 1911), Homoeoxipha obliterata (Caudell, 1927) and Natula matsuurai Sugimoto, 2001, each of them belonging to a different genera. Among them, the former two are reconfirmed since earlier records, and latter two are newly recognized genera and species from the far southern provinces Jeollanam-do and Jeju-do Island in Korea. The type locality of both crickets is Japan, and are also only previously referred to in Japan, but their distributional ranges include neighboring South Korea. A key to the species, descriptions, photographs, figures, and oscillograms of male's calling sounds are provided to aid their identification.
