Fern-feeder aphids (Hemiptera: Aphididae) in China are represented by 13 species in 10 genera, including a new genus, Vietaphisgen. nov., a new species, Vietaphis aliquantussp. nov., from Guizhou and Tibet on Plagiogyria japonicum, and a new subspecies, Amphorophora scabripes galbassp. nov., from Guizhou on Pentarhizidium intermedium. Two genera, Amphorophora Buckton and Idiopterus Davis, and four species or subspecies, Amphorophora ampullate bengalensis 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 Neomacromyzus 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 aliquantussp. nov., Amphorophora scabripes galbassp. nov., and Myzus filicis are presented.
