A ricanid planthopper, sometimes so called Ricania shantungensis, has been regarded as a serious invasive pest in Korean peninsula. It belongs to family Ricaniidae comprised of 40 genus and more than 400 species worldwide, and only 6 species recognized in Korea. The invasive planthopper has a wide host range including economic agricultural crops such as apple, peach and pear. In the meantime to investigate natural enemies for biological control, we have found an egg parasitoid. In this study, we report a new species of genus Phanuromyia, an egg parasitoid of the ricanid planthopper. Morphological characteristics of male and female are described in detail with high resolution images.
