In addition, the following genera are classified as members of Diaspidini with uncertain placement to subtribe (incertae sedis): Furchadaspis MacGillivray 1921 Gadaspis Borchsenius 1949 Ischnaspis Douglas 1887 Nimbaspis Balachowsky 1952 Prodiaspis Young 1984 Pygalataspis Ferris 1921 Roureaspis Takagi 1997 Trischnaspis Ben-Dov 1974
Six additional subtribes have been recognized in the past. According to research published in 2019,
Protodiaspidina and Phenacaspidina are now included in Chionaspidina. Augulaspidina and Kuwanaspidina are now included in Fioriniina. The species formerly in Sclopetaspidina and Xerophilaspidina have been classified in various subtribes, tribes, and subfamilies.
