The genus Meleonoma comprises 93 species. Wang et al. (2020) divided these into eight species groups. In Japan, nineteen species of this genus have been recorded and they are divided into six species groups, including two new species groups. The revision is divided into three parts. In this part, eight species are reported, of which three species, Meleonoma milichopis sp. nov., M. persimilis sp. nov., M. ryukyuensis sp. nov., are described as new to science, and one species, M. facialis Li & Wang, 2002, is redescribed as new to Japan. The adult specimens, wing venations, male and female genitalia are illustrated in detail.
