Nine species of Aulacaspis recorded from plants of the family Rosaceae or the Ericaceae and another species from a supposedly ericaceous plant are mentioned in an annotated list. Five of them and four new species associated with plants of the mentioned families are lumped together under the rosae group, and two others, associated with plants of the rosaceous genus Rubus, under the megaloba group. The rosae group is divided into two subgroups: one of them is composed of A. mali, A. ericacearum, A. sorbi, n.sp., and the broadly distributed A. rosae, the former three species being restricted in distribution to northeastern Asia; the other subgroup contains A. altiplagae, A. langtangana, n.sp., A. pieridis, n.sp., A. lyoniae, n.sp., and the broadly distributed A. rosarum, the former four species occurring in the Himalayan-Tibetan region. A. megaloba and A. amamiana represent the megaloba group, which, probably including unnamed forms, is distributed in southern areas in eastern Asia.
