This is an appendix to a larger paper embodying a revision of some sections of the genus Tripteroides in the Oriental Region. It deals with associated changes at the subgeneric level in the Australasian members of the genus, notably the resurrection of Polylepidomyia from synonymy as a valid subgenus and the transfer to it of all Australasian species currently included in Rachionotomyia. At the same time two species (mabinii, szechwanensis) are removed from Rachisoura, rendering it purely Australasian, and two others are transferred to it from Rachionotomyia which then becomes purely Oriental. The two unornamented Australasian subgenera are thereby rendered more readily distinguishable from one another and from Rachionotomyia. Similar changes affecting the Oriental fauna are noted. Further changes may well be needed when the genus is fully revised.
