Background: The genus Tuponia Reuter, 1875 belongs to the subfamily Phylinae and comprises 91 species worldwide. Before this study, only T.koreana Kim & Jung had been recorded from the Korean Peninsula.
New information: Two species of Tuponia Reuter, 1910 are recognised from the Korean Peninsula including the first record of T.mongolica Drapolyuk, 1980. T.koreana Kim & Jung, 2021 is proposed as a junior synonym of T.chinensis Zheng & Li, 1992. The species is identified, based on the dorsal habitus and male and female genitalic structures. A brief discussion of the distribution of Korean Tuponia species also is presented.
