The Phylogeny of the Genera in the Tribes Deltocephalini, Paralimnini , and Their Allies (Homoptera, Cicadellidae, Deltocephalinae)

The phylogenetic relationship among the genera of the subfamily Deltocephalinae and its allies occurring in Japan is studied, and the tribes Deltocephalini and Paralimnini are redefined. The phylogenetic analyses were based upon the maximum-parsimony method by the manual and computer-aided reconstruction with the Fitch characters and Wagner characters (non-weighted or weighted). Sixty-four characters were used for the phylogenetic analyses. Deltocephalini s. str. was concluded to be paraphyletic and includes 2 lineages. The Deltocephalus clade consists of Alobaldia, Deltocephalus, Endria, Recilia, and Paramesodes. Contrary, Futasujinus, Hengchunia, Takagiella, and Yanocephalus belong to the Paralimnus lineage with Paralimnus, Paralaevicephalus, Psammotettix, Metalimnus, Diplocolenus, Jassus, Sorhoanus, Doratura, and Aconurella. The Deltocephalus clade was referred to the tribe Deltocephalini and the Paralimnus clade to the tribe Paralimnini.
