본 연구에서는 국내에서 처음 발견된 Aulacophoroides hoffmanni (Takahashi, 1937)를 최초로 보고한다. 2024년 야외조사에서 한국의 서부 2개 지역의 등나무(Wisteria floribunda (Willdenow))에서 심각한 피해를 주고 있는 A. hoffmanni를 확인하였다. 무시성충의 상세한 형태 기재와 계측값을 제시하였으며, 생체 및 슬라이드 표본 사진을 포함하였다. 이 종은 등나무에 심각한 피해를 주고 있어 관상용 등나무의 주요 해충이 될 것으로 예상된다.

The Genus Greenidea includes 66 species worldwide. Only two species have been recorded in Korea: G.kuwanai and G.nipponica. We collected Greenidea nigra Maki, 1917 on Quercus glauca in Jeju. This species has been recorded in Japan and Taiwan. In this study, we report this species for the first time in South Korea, and describe morphological features of apterous viviparous females.

The aphid genus Macromyzus Takahashi is a small East-Asia genus of the tribe Macrosiphini (Hemiptera: Aphidinae). Globally, there are five recognized species: Macromyzus (Anthracosiphoniella) maculatus (Basu), Macromyzus (Macromyzus) indicus David & Narayanan, M. (M.) manoji Raha & Raychaudhuri, M. (M.) spinosus Su & Qiao, and M. (M.) woodwardiae (Takahashi). In this study, we report the first record of the aphid genus Macromyzus Takahashi in Laos. We present a decription of a new species of this genus associated with Diplazium esculentum (Retz.) Sw. (Athyriaceae). Additionally, for the first time, we conducted scanning electron microscopy research on the morphology and sensilla of representative of this genus.

The aphid genus Tuberaphis Takahashi belongs to the tribe Cerataphdini (Hemiptera: Hormaphidinae) and comprises 17 valid species. Generally, its species are distributed in East and South East Asia, where they primarily feed on Styrax spp. (Styracaceae) and utilize species within the Loranthaceae family as their secondary hosts. They form various shapes of galls on Styrax, looking coral and broccoli etc. Currently, the only aphid species reported to exclusively produce gall forms resembling broccoli head-shaped is Tuberaphis takeouchii (Takahashi). For the first time in Korea, an aphid species forming gall structures with a broccoli-head-like appearance has been discovered. We confirmed that the species discovered in Korea is a new species through morphological and molecular comparisons with T. takenouchii (Takahashi). To comprehend the life cycle of this new species, we conducted a year-long study investigating how the gall forms change and examined aphid polymorphism across different seasons. The results of this study additionally include as followings: 1) Species identification, 2) DNA barcoding, 3) population genetic analyses, and 4) morphological comparison using SEM
