Cixiinae
Cixiinae is a planthopper subfamily in the family Cixiidae. It is one of three such subfamilies, the other two being the Bothriocerinae and the Borystheninae. While a few species had been tested in a larger study of the Fulgoroidea, neither the Cixiinae nor its tribes were analysed cladistically until 2002. Resolution of tribal relationships is incomplete and additional testing of the tribes with samples larger than one per tribe is needed.
