The following six species are newly recorded from Vietnam: Eulachnus thunbergii (Wilson, 1919); Sarucallis kahawaluokala- ni (Kirkaldy, 1907); Neophyllaphis podocarpi Takahashi, 1920; Cavariella araliae Takahashi, 1921; Aleurodaphis blumeae van der Goot, 1917; Astegopteryx styracophila Karsh, 1890.
