Fern-feeder aphids (Hemiptera: Aphididae) in China are represented by 13 species in 10 genera, including a new genus, Vietaphis gen nov., a new species, Vietaphis aliquantus sp nov., from Guizhou and Tibet on Plagiogyria japonicum, and a new subspecies, Amphorophora scabripes galba ssp nov., from Guizhou on Pentarhizidium intermedium. Two genera, Amphorophora Buckton and Idiopterus Davis, and four species or subspecies, Amphorophora ampullate ben-galensis Hille Ris Lambers and Basu, Idiopterus nephrelepidis Davis, Micromyzodium polypodii Takahashi, and Myzus filicis Basu, are reported for the first time in China. Apterae and alatae of Myzus filicis are redescribed herein, and with host plant notes. The fern-feeder aphid genus Ne-omacromyzus Lee is considered a junior synonym of Idiopterus. Furthermore, Neomacromyzus cyrtomicola Lee is transferred to the genus Idiopterus, as Idiopterus cyrtomicola (Lee), comb nov., which is herein considered a junior synonym of Idiopterus nephrelepidis Davis. Keys to Chinese fern-feeder species are provided. Morphological figures and biometrical data of Vietaphis aliquantus sp nov., Amphorophora scabripes galba ssp nov., and Myzus filicis are presented.
