New records of the genus Micromyzodium (Hemiptera: Aphididae) from Korea

- The genus Micromyzodium David is newly recognized in the Korean Peninsula.
- Two Micromyzodium species were collected on Fatoua villosa and Perilla frutescens.
- These species are Micromyzodium kuwakusae Uye and M. nipponicum Moritsu.
- We redescribed, illustrated, and measured characteristics for apterous viviparae.

The aphid genus Micromyzodium David, 1958 is newly recognized in the Korean Peninsula. This genus is characterized by very long dorsal abdominal hairs, almost 3 to 4 times as long as the basal diameter of antennal segment III. Colonies of two Micromyzodium species, Micromyzodium kuwakusae Uye, 1924 and Micromyzodium nipponicum Moritsu, 1949, were collected on Fatoua villosa Nakai (Urticales: Moraceae) and Perilla frutescens Britton (Lamiales: Lamiaceae), respectively. In this study, important characteristics are redescribed, illustrated, and measured for the apterous viviparous females of these species.
