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.[1] While a few species had been tested in a larger study of the Fulgoroidea,[2] neither the Cixiinae nor its tribes were analysed cladistically until 2002.[1][3] Resolution of tribal relationships is incomplete and additional testing of the tribes with samples larger than one per tribe is needed.[4]
